Abstract. Edge architectures have emerged as a solution for the development of Internet of Things (IoT) applications, especially in scenarios with ultra-low system latency requirements and a huge amount of data transmitted in the network. This architecture aims to decentralize systems and extend cloud resources to devices located at the edge of networks. Various benefits regarding local processing, lower latency, and better communication bandwidth can be highlighted. This study proposes an edge architecture which uses computer vision to detect people in agglomerations. To evaluate the performance of the proposed architecture, an use-case for agglomeration detection in the Covid-19 scenarios is presented. A comparative analysis of the detection is performed through videos from a public database. The obtained results demonstrate a gain in terms of computational performance with a video analysis in comparison to the best solutions available in the literature. The proposed solution can be a powerful edge tool to support the combat against Covid-19 Pandemic. Keywords: Edge architecture · Internet of Things · Computer vision · Covid-19
1 Introduction Internet of Things (IoT) has gained great attention due to the proliferation of a huge quantity of data generated from connected devices which allows the monitoring and processing of sensors data anywhere and at any time. The internet has revolutionized the world through the offering of global connectivity [1] and IoT is set to sustain significant change on the evolution known as the next generation of the internet. Moreover, the combination among IoT and different technologies has contributed to raise the Quality of Services (QoS) in several applications in modern days, such as smart home, connected cars, smart cities, IoT in agriculture, energy management and IoT health care.

IoT-based projects is taking us on the journey where the main goal is for transforming an essentially [2]. The concept of edge architecture was introduced in order to mitigate this issue. Processing of data is realized at the edge of network employing the existent resources locally and just the result of processing is sent to the cloud. Therefore, it reduces the network resource occupancy drastically, because only a small fraction of all existent data is transmitted [3]. For example: a hypothetical application where a smartphone records a video to detect an object is present to highlight the benefits of the edge processing. This device uses its own local camera to make a video, applies filters on the image, performs a detection algorithm and only then report the result to the cloud [4]. In this example, it is possible to save energy resources through reducing the amount of data and computing power and get the result much faster in comparison to the cloud architecture. Due to a massive production of IoT devices, the world just arrived in the post-Cloud era [5], in which the devices localized on the edge of networks consumes these data and report only status to the cloud servers. Some applications allow your information to be transmitted and processed by a server on the cloud, but other applications, such as video processing, produce a large amount of data and require very short response time. Also, these applications may contain private data that need to be processed before the transmission to the cloud. Cloud architectures are not recommended for applications in which uploading and processing a huge quantity of data could lead to long time operations due to the transmission latency. The year 2020 has been an atypical year because the world is facing a new and huge threat, the Covid-19 Pandemic, as named by the World Health Organization (WHO). In September 2020, numbers have risen over 27 million confirmed cases, and the number of deaths has exceeded 900 thousand. The America Continent is leading in number of confirmed and death cases, which is concerning. Brazil is the third most affected country after the United States and India [6], because of that, many cities have been locked down due to this rapidly spreading virus [7, 8]. The technology has taken an important role in the mission of combating this virus by the creation of new mechanisms to control Covid-19 spread. Significant efforts are being made on the available healthcare facilities, treatment systems and many advanced solutions are appearing in order to reduce the problems related to the pandemic [9, 10]. In this context, the main objective of this work is to carry out performance evaluation of a computer vision algorithm to detect agglomeration using edge architecture responsible for send alert messages to the authorities about people proximity with the objective to avoid Covid-19 spread. The proposed approach aims to minimize the necessary network resources usage to process the images on the cloud due to the huge quantity of data from surveillance cameras. This can be achieved by shifting the resources hosted on the servers for near the edge of the network. Moreover, a motivation for deploying the new computer vision algorithm comes from the need of achieving high accuracy by the usage of an equipment with low computational power to detect people. Then, the most important contributions of this study are shown below: • The benefits of reducing the amount of data transmitted because of the processing in the edge of networks in contrast to sending all data to cloud server to be processed;

• Deployment of a new computer vision algorithm for detecting people in real-time applications employing a low computational power equipment; • A comparative analysis among the state-of-the-art computer vision algorithms to detect objects with the proposed scheme; • Performance assessment of the proposed solution, which can serve a basis for the development of other systems in Covid-19 Scenarios. The remainder of this paper is as follows. The most relevant works on the topic are discussed in Sect. 2. Section 3 presents the edge scheme used to deploy the proposed system and its benefits. Section 4 describes the proposed algorithm, explaining the motivation for its usage and providing details of its deployment. Section 5 shows the middleware communication, demonstrates how data will be exchanged (end-to-end). In Sect. 6 the experimental results are presented and, then, the work is concluded in Sect. 7, including suggestions for further works.
2 Related Work 2.1 IoT and Egde Applications Weisong Shi et al. introduce the concept of Edge Computing in [11], in which the main applications according to the metrics of computing power, latency, battery life of mobile devices, bandwidth costs, security, and privacy are shown. According to Shi, Cloud Computing is a centralized architecture which receives data of all the devices connected and processes the information. In the opposite way, Edge Computing is a decentralized architecture which makes use of the resources locally, consequently the computing happens nearer the data sources, and transmit only the results to the Cloud. Shi also describes two examples optimized by Edge Computing implementation. The first one is an example of an online shopping and the second one is an example of searching the missing child through the surveillance cameras. In [12], Zhao et al. also propose a IoT based system which contains heterogeneous interconnected devices on the Edge Server, but the main goal of this work is the routing of data packets. Zhao et al. utilize traffic metrics of diversity and wireless diversity to increase the network throughput to deploy a three-phases approach: (i) Discretization of the whole IoT network into small network and the definition of the candidate route; (ii) The analysis of each candidate route by utilizing metrics of performance gain, link quality and link correlation; (iii) The deployment algorithm focuses on optimizing the utility metric. The experiments results show a greatly improvement on the routing packets and, consequently, on the throughput. Ksentini and Brik in [13] propose a new edge scheme to detect social distancing, which consists to send the geolocation coordinates from user’s smartphone to an application sitting at the edge. The distance euclidean among everyone located under the edge coverage is calculated and the users that are breaking the social limit are warned by an app at their smartphones. A case study utilizing the European Telecommunications Standards Institute (ETSI) multi-access edge computing (MEC) ecosystem is presented. Important parameters for edge scheme as low latency, near-real-time reaction, privacy and anonymity are highlighted. The obtained results show that proposed scheme is an efficiency option to inform people about the distance each other.

2.2 Algorithm of Computer Vision to Detect Objects Several algorithms for detect object have been proposed in the literature in order to improve the performance of the used device and minimize human interaction in this process, among which it could be mentioned R-CNN, Yolo and SSD. In [14], an algorithm called Regions with Convolutional Neural Network (R-CNN) is presented. It considers segmentation of each frame in 2000 regions and applying into a convolutional neural network (CNN) to identify the target through selective search. However, it was identified a low performance due to the processing of multiple regions [15, 16] and an improvement was made using the full frame in CNN instead of segmentation. The result is a map of characteristics to make the target prediction and it was called Fast R-CNN [16]. In order to increase more efficiency to this algorithm, a new improvement was performed and selective search was replaced by another CNN [17]. This new algorithm received the name of Faster R-CNN. Yolo (You Only Look Once) was developed by Joseph Redmon et al. [15, 18], in 2015. Yolo analyzes a full image to make object detection. The task of object detection, determines the location of the target into the image and classifies it according to a class. Yolo “only looks once” on the image in the sense that it requires only one forward propagation pass through the CNN to make the detection. A stage of non-max suppression is executed and the objects detected are showed together with bounding boxes on the output of the process. Redmon et al. [19] enhanced Yolo Algorithm with the detection of over 9000 object classes by jointly optimizing the detection and classification stages. Another enhancement in Yolo is shown in [20], called YoloV3. Redmon and Farhadi propose a new network for performing feature extraction through a CNN of 53 layers. Yolov3-Tiny is a variant of YoloV3, which takes less time to run, but its results have less accuracy. In [21], Wei Liu et al. propose the Single Shot Multibox Detector (SSD) Algorithm to detect the target using a full frame. Its operation is based on the extraction of features through several CNN in order to identify the content of the images. Its accuracy and processing rate are higher than Yolo and lower than Faster R-CNN. The SSD Algorithm will be further explained in Sect. 4.2. The present work considers the SSD Algorithm as it requires a lower processing in comparison to R-CNN and Yolo, in consequence of that, it can be used in embedded hardware equipment with low computation power. It is seen that there are relevant contributions in the literature related to edge/cloud architecture, computer vision algorithm, and Technology for Covid-19 scenarios. These works are considered in the proposal of an Edge Architecture to detect agglomeration presented in this study.
3 Proposed Edge Architecture This section presents the proposed Edge Architecture to detect agglomerations on Covid19 Scenario through the use of a computer vision algorithm. The Fig. 1 illustrates the whole architecture composed by devices on the edge of networks, cloud and user application. The largest computational effort is localized on the edge, where the videos are captured from surveillance cameras, the images are processed, and the people contained on

each image are checking. Then, the SSD Algorithm is started up to detect the localization and the reliability of the data generated from these people previously checked. Finally, the quantity of individuals, the distance among them are calculated. The information are sent to cloud server, and then to the monitoring center. The data are exchanged through the well- known Message Queuing Telemetry Transport (MQTT) Protocol [22].
Fig. 1 Overview of the proposed edge architecture to detect agglomeration
When any distance is less than one meter, a warning event is sent to indicate agglomeration with information about geolocation and the number of people. These information allow the responsible person to monitor locations in order to mitigate the risk of contamination. The main advantages of the proposed Edge Architecture are local processing of videos [23], energy consumption, latency and bandwidth [24].
4 Computer Vision Based on Difference of Frame in Single Shot Detection Algorithm In this section, an enhancement on the SSD Algorithm is proposed and named Computer Vision based on Difference of Frame in Single Shot Detection Algorithm (CVDF-SSD). Firstly, the images are captured from surveillance cameras in RGB color domain and a pre-processing is realized to evaluate if there are people in the current frame. Based on this analysis, the employment of a detection algorithm on every frame could be eliminated. This step is very important, as it allows an increased processing rate on the Raspberry PI without losing accuracy. Then, SSD Algorithm is applied to analyze the frame, to detect people and count the amount of people in the images. When this detection is concluded, a rectangle is drawn around each person and its central coordinate (x,y) is identified. Finally, the distance among people are calculated. When there is a proximity of less than one meter, the respective distance is highlighted, which may indicate a potential risk of Covid-19 contamination. The structure of CVDF-SSD is discussed, in detail, as follows. The Fig. 2 describes the flow of whole system. 4.1 Evaluation of Frames Based on Difference of Frame This stage has the objective of enhancing the processing rate through a selective application of SSD Algorithm.

detection through deep learning. It is an important requirement for IoT equipment with limited computational power. Initially, the video is analyzed and the frames are captured in the RGB (Red, Green and Blue) color domain. For example, the black color is the RGB (0,0,0), the white color is the RGB (255,255,255), the yellow color is the RGB (0,180,180) and the violet color is the RBG (180,0,180). Another option is using the gray color domain, where the three colors of the RGB domain have the same intensity and they are processed by an array of a single dimension. The scale of gray color starts with black color, represented by RGB (0,0,0), goes through several shades of gray and reaches the saturation in white color, represented by RGB (255,255,255). The equation to convert RGB domain to the Gray domain is shown by (1), where Gray, B, G and R are matrices of the same dimensions. Gray = 0.299R + 0.587G + 0.114B.
(1)
Despite the benefit of gray color domain, a domain conversion from RGB to Gray domain and some time is spent in this task. So, for reducing the processing time at this task, it is used the RGB domain frames and it performs mathematical operation of the absolute difference between current and previous frame. As a result, a predominantly black frame which has colors only in the variations areas is obtained. This behavior occurs because the operation of the absolute difference is simpler than the operation for converting to Gray domain, resulting in the hardware processing it quicker. Equation (2) shows the operation of the difference of the frames: D = |C − P|.

where D, C and P represent the difference of frame matrix, current frame matrix and previous frame matrix, respectively. Noise cancellation is executed to mitigate false detection of people and avoid an unnecessary processing time. It is initiated by background subtraction [25], which eliminates the background static parts and leaves only the foreground mobile parts. Then, the colored remained are converted to black and white image through an operation called binarization. It consists of defining a reference color threshold, in which the brightest

colors are changed to white color and the darkest colors are changed to black color. The threshold used is RGB (100,100,100). Finally, the operation of morphology of the binarized frame cancels the remaining noise, which reduces white points of black background, black points within the target detected and exhibits the people well defined in the frame. 4.2 SSD Algorithm The Single Shot Detection (SSD) Algorithm [21, 26] divides the task of people detection in two distinct stages: classify the image on classes and detecting the object on image. Classify stage [27]: The image is classified among one thousand pre defined classes, where one class is defined as background to represent the image which does not contain the other 999 classes. Each image creates a vector of 1000 elements and each one contains the probability of the classes on the image. This classifying stage is quick because it divides the convolution operation in two layers: depthwise and pointwise convolutions. Depthwise convolutions apply a single filter per each input channel (input depth) to split into smaller channels. For example, the result of a Depthwise convolutions applied in the input of M channels will be M outputs of single channel. Pointwise convolution is a 1 × 1 convolution used to create a linear combination with the M outputs of depthwise layer. Detect stage [21]: This stage is responsible to detect the object on the image through its reliability and location. It is based on a feed-forward CNN which produces bounding boxes and object scores contained in the boxes according to the pre-trained classes. After that, the operation of non-maximum suppression is applied to produce the final detection. During the classification time, SSD Algorithm uses 8,732 boxes to find the box that most overlaps with the bounding box, which contains the objects according to the aspect ratio, location and scale. Then, a non-maximum suppression layer is used to remove other overlapping boxes in order to keep only one bounding box per object contained in the image. Non-maximum suppression layer uses the Intersection over Union (IoU) as a parameter to decrease the quantity of boxes.
5 Middleware Connectivity The use of a middleware connectivity is important to warn public authorities when a place is identified with people agglomeration. This warning event minimizes the probability of contamination by Covid-19 and increases the health security for these places because the monitoring is made remotely, which avoids the employment of people to surveillance these locations. In.IoT is an middleware which performs the tasks for receiving, storing, and publishing information to subscribers [28]. The communication protocol chosen to access In.IoT is the MQTT [22] because it requires low complexity deployment and low computational power. Figure 3 shows a case study of the proposed Edge Architecture which utilizes the CVDF-SSD Algorithm. The agglomeration monitoring is made through video surveillance of cameras installed at the Municipal Market of São Paulo and accessed from a

public database of São Paulo, Brazil [29]. The original frame captured from cameras is shown in Fig. 3a. When the CVDF-SSD Algorithm is applied on the video, the number of people and the distance between them are calculated, as it is depicted in Fig. 3b. So, the information is published and the public authorities responsible can plot it in a city map to know where the agglomerations are occurring, as it is illustrated in Fig. 3c.

6 Performance Evaluation and Results Analysis The proposed CVDF-SSD Algorithm for Edge Architecture is evaluated and the results are presented in this section. The images processing is made by a Raspberry Pi 3 Model B + board and the reason by your choice is because it is a cheaper, portable and small equipment and it could be easily installed in several places. In IoT Middleware is the backbone utilized to interconnect devices on the edge with applications of users and its role in this work is to transmit the agglomeration status. An additional communication overhead introduced by it and by transport protocol is not assessed. Videos from a public database of São Paulo [29] were used for comparison purposes. The solution was carefully studied to be as less invasive as possible and ensure privacy of people. Then, the faces of people used were blurred to maintain them anonymous, as shown in Fig. 3b.

The experiment results are presented in order to compare the people detection task of CVDF-SSD Algorithm with traditional and state-of-the-art SSD Algorithm and YoloV3Tiny Algorithm in terms of processing rate and time. It is using the Deep Neural Network (DNN) module from Open Source Computer Vision (OpenCV) library. CVDF-SSD Algorithm, SSD Algorithm and YoloV3-Tiny Algorithm are using pre-trained model on the Common Objects in COntext (COCO) [15]. Table 1 demonstrates a notable difference of processing among the schemes. The processing time is measured running the same part of video for the three analyzed algorithms. The measurements are performed thirty times and the result is an average of them. This proves that is possible to detect people using deep learning algorithms in an equipment of low computational power without the loss of accuracy in the detection.

The pre-processing stage of CVDF is evaluated in terms of reliability [30]. According to Wiedemann et al., the metrics to indicate the level of accuracy of the system is divided in three statistical measures and are defined as follows. Precision = TP/(TP + FP)
(3)
Recall = TP/(TP + FN)
(4)
Quality = TP/(TP + FP + FN).
(5)
In order to guarantee the results reproducibility and mitigating any variation, CVDF is executed one thousand times. The frames are sampled and the number of people detected correctly, wrongly and the number of people not detected are counted manually. Table 2 shows the CVDF pre-processing detected people on images with Precision of 92%, Recall of 85%, and Quality of 83%. Therefore, it demonstrates a powerful option to trigger the people detection algorithm and enhances the processing in equipment with low computation power.
7 Conclusion and Future Works In this paper, a new computer vision algorithm to detect agglomerations using an edge scheme was proposed. The motivation and main benefits by employing the edge architecture were described. Also, it was shown the role of IoT technology in the Covid-19 scenarios which motivates to deploy a new algorithm to detect agglomeration.

It is possible to observe from the results that CVDF-SSD Algorithm has an excellent performance due its efficient way of identifying humans on images. Compared to other solutions, the proposed algorithm is capable of enhancing the processing and of achieving high accuracy. Finally, a case study to alert public authorities at the Municipal Market of São Paulo city, in Brazil, was presented and some scenarios to avoid contamination by Covid-19 in agglomerations was described. By the combination of Raspberry Pi on the edge of network and the proposed CVDF-SSD Algorithm, the people social distance is found with high accuracy and the surveillance people are warned in real-time. Thus, the proposed architecture achieves its purpose of processing the videos locally to reduce latency, bandwidth and consummation of energy. As a future work, it is suggested an intelligent integration among the edge devices for identifying a metropolitan area in risk of Covid-19 contamination and alert the population nearby in their smartphone about this risk.

It assists the histopathologists to achieve accurate results through progressively fast, steady, objective, and measured examination. In this paper, a systematic survey has been conducted to introduce the improvement history and locate the future competence of Deep Learning calculations in the Breast Histopathological Image Analysis (BHIA) field.

1 Introduction Breast cancer (Bosom malignancy) is a kind of ailment that begins with the uncontrolled proliferation of breast cells. Breast cancer can occur in women and even occasionally in men. Side effects of breast cancer growth are visualized as a bump for the breast, gruesome release from the breast, and significant changes in the shape or surface of the areola or breast. Its treatment relies upon the phase of cancer. Hematoxylin and Eosin (H&E) contain bosom tissue tests from biopsies, seen under a magnifying lens instrument for the essential conclusion of the bosom cancer [1]. For identification of the bosom malignant growth, mammographic pictures are being utilized [2] in most of the cases. However, contemplates have demonstrated that thermographies pictures © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2022 V. E. Balas et al.

(warm infrared pictures) bring about the instance of bosoms of youthful females [3]. The dynamic thermography strategy is cheaper than the mammography and attractive reverberation imaging strategies [4]. Mammography is one of the gold standard image capture technique used for detecting breast-related problems. However, this technique has some limitations like it may increase false-positives and false negatives because mammograms cannot detect denser breasts in women, which can hide tumors [5]. Also, the imaging procedure done in mammography causes discomfort to the women, and this image formation depends on the X-ray radiation, posing a risk for patients [6]. The histological type of Breast cancer was performed according to WHO (World Health Organization) classification, and grading was performed according to the Modified Bloom-Richardson grading system [7]. Breast cancer is categorized into two phases as in-situ carcinoma and invasive (infiltrating) carcinoma. In situ carcinoma contain two parts: Ductal and lobular. Ductal has divided into five categories—Micropapillary, Cribiform, Solid, Comedo, and Papillary, which are based on tumor architectural features. Invasive carcinomas are the gathering of tumors which are additionally grouped into subtypes. The invasive tumor types incorporate penetrating ductal, mucinous, cylindrical, obtrusive lobular, ductal/lobular and medullary papillary carcinomas. The invasive tumor type like Infiltrating Ductal, based on different levels of tubule formation, nuclear pleomorphism, and mitotic index, are further sub-divided as Grade 1 known as separated, Grade 2 as reasonably separated and Grade 3 as ineffectively separated [8] as represented in Fig. 1.

1.1 Symptoms of Breast Cancers Include • a bosom irregularity or tissue thickening that feels not an equivalent encompassing tissue and has grown lately • breast torment • red, pitted heal the entire whole bosom • swelling in bosom • bloody release from areola aside from bosom milk • peeling, scaling, or chipping of skin on areola or bosom • inverted areola • change fit as a fiddle or size of bosoms • swelling in armpit. 1.2 Stages of Breast Cancer Bosom disease development is often isolated into stages subject to how colossal the tumor or tumors are and, therefore, the sum has spread. Huge malignant growth developments have assaulted almost all tissues or organs at a better stage than infections that are on the brink of nothing but still contained within the bosom. To mastermind a phase of bosom malignancy, we would like to understand: • • • •
if the malignancy is obtrusive or noninvasive how significant the tumor is to check whether the lymph center points are incorporated if the malignancy has spread to close tissue or organs (Fig. 2).

Stage 0 breast malignancy DCIS is in Stage 0. The cancer cells in DCIS stay limited to the channels in the breast, and they do not spread into close-by tissue. Stage 1 breast malignancy • Stage 1A: The size of the essential tumor is two centimeters wide or less, and the lymph hubs are not influenced. • Stage 1B: The cancer is found close by lymph hubs, and in the breast, there is either no tumor or tumor that is smaller than two cm. Stage 2 breast malignancy. Stage 2 breast malignancy • Stage 2A: The tumor has spread to one–three close-by lymph hubs and is tinier than two cm, or it is somewhere in the range of 2–5 cm and has not spread to any lymph hubs. • Stage 2B: The tumor is somewhere in the range of 2–5 cm and has spread to 1–3 axillary (armpit) lymph hubs, or it is more significant than five cm and has not spread to any lymph hubs. Stage 3 breast malignant growth • Stage 3A: The malignant growth has spread to four–nine axillary lymph hubs or has accelerated the indoors mammary lymph hubs, and the essential tumor can be of any size. • The tumors are extra noteworthy than 5 cm, and the disease has spread to one-three axillary lymph hubs or any breastbone hubs. • Stage 3B: A tumor has attacked the chest divider or skin and might have attacked up to nine lymph hubs. • Stage 3C: Cancer is found in at the last ten axillary lymph hubs, lymph hubs close to the collarbone, or inner mammary hubs. Stage 4 breast malignant growth Stage 4 breast cancer growth can have a tumor of any size, and its disease cells have spread to close by and removed lymph hubs just as far off organs.
2 Related Work By using noninvasive and biopsy methods, we can detect and diagnose breast cancer. The Noninvasive method is image procedure, including diagnostic mammograms such as x-ray, Magnetic Resonance Imaging (MRI) of the breast, sonography, and thermography. This procedure is used for screening cancer, whereas the biopsy method confirms the presence of cancer. The biopsy method includes Core Needle Biopsy, Fine Needle Aspiration (FNA), Vacuum-Assisted Breast Biopsy and Surgical (open) biopsy stand out.

For those, we need samples of cells or tissue which are collected on a glass microscope slide for detection, as shown in Fig. 3

The term cytology is derived from the Greek word kytos, which is a combination of two parts. First is cyto means ‘cell’, and ology means the study. So, it is a study of cells that define how cells grow, work, and proliferate as shown in Fig. 4

Deep learning: Deep learning is a method of multilayer architecture where the input data is applied or passed at different levels of abstraction, resulting in the extraction

of features. Each layer is a “distributed representation” of given inputs, and this representation is a unit of vectors for extract results with specific features. Each input has separate features for the layer of each unit, and these results are not mutually derived. Two significant utilization of deep learning is relapsed and characterization. For each situation, there is prepared information, utilized to alter loads that limit misfortune work (target work). Most normal malignant growth among ladies is breast disease. There is a consistent need for progression related to clinical imaging. Early discovery of malignant growth, followed by the best possible treatment, can lessen the mortality rate. AI can assist clinical experts in diagnosing the disease with more accuracy where profound learning or neural systems is one of the strategies which can be utilized for the characterization of ordinary and strange bosom recognition. CNN can also be utilized for this study. Fig. 5 represents that deep Learning approach as a subset of the Artificial Intelligence domain.
Fig. 5 Deep learning
The necessary steps of the Deep Learning approach are depicted in Fig. 6. The image dataset is split into train and test dataset. Training samples are taken to train the deep learning model along with the class labels. Unknown samples are taken from the test datasets, and their class labels are predicted by the trained Deep learning model to detect and classify cancer.
3 Literature Survey This section presents the prior techniques as proposed by various researchers. Wang et al. [13] investigated a bosom CAD technique reliant on the combination with Convolutional Neural Network (CNN), where features like morphology, texture, and density

were selected and fused. Then, it was classified as benign (or) malignant using the ELM classifier. They have worked with 400 mammograms that contain 200 malignant and 200 benign images along with the performance metrics, such as detection and diagnosis metrics. Detection metrics like misclassified error, area over-covered metrics, area over-segmentation metrics, and under-segmentation metrics and comprehensive metrics, whereas diagnostics metrics such as accuracy, specificity, sensitivity, and area under curves were measured and achieved with better detection and diagnostic rate. However, the challenging part is the selection of the appropriate features. The development of a feature for a fused set enhanced the complexity of the training classifier. Xu et al. [14] demonstrated a critical step in automatic nuclei detection as an evaluating of bosom malignant growth tissue examples. Stacked Sparse Autoencoder was acquainted with distinguishing the high-goals histopathological pictures of bosom malignant growth. He worked using a set of 537 H&E stained histopathological images. Based on generated ground truth details, metrics such as precision, recall, and F-measure were evaluated. The autoencoders have achieved 78% accuracy comparing with other models. The major limitation is sensitivity analysis as smaller the window size settings, more with be the complexity. Saha and Chakraborty [15] observed a profound (deep) learning based Her2Net [15] that was created for cell layer, core location, division, and characterization. It is made of different convolution layers, max-pooling layers, spatial pyramid pooling layers, deconvolution layers, up-inspecting layers, and trapezoidal long momentary memory. The performance of LSTM has enhanced to improve the system performance through

the utilization of the Her2 Image database. Patches of images are created with size 251 * 251 of 2048 pixels with 98% accuracy. However, the limitation of the system is that they have achieved an exceptionally low false-positive rate. Patch-based segmentation models should be enhanced further for decision-making systems. Brancati et al. [16] defined a Deep Learning approach, used for breast invasive ductal carcinoma detection and lymphoma multi-classification in histological images [16]. The authors explored an automatic analysis of hematoxylin and eosin-stained in breast cancer images using deep learning methods. It has been projected in two cases, namely, the presence of invasive ductal carcinoma and its lymphoma classification. FusionNet was developed from Convolutional Neural Networks. It has been applied to public datasets, namely, Unet and Resnet. In Comparison with previous algorithms, the detection rate has increased by 5.06%. FusionNet demonstrated a solution for the segmentation process, but still, feature selection remains unresolved. Based on votes received in each patch, the class of the cell is detected. Qi et al. [17] developed learning models for enhancing the detection accuracy of the system. Here, two learning models were suggested, first is the entropy-based strategy, and the second is the confidence-boosting strategy. Specifically, in every query, the deep model is fine-tuned with both high-confidence and entropy samples. Breakhis is an annotated dataset, in which image-level accuracy and patient-level accuracy were tested. The limitation is that on increasing the sample size, the classifier’s performance gets reduced. Limited labeling degrades the efficiency of the classifiers. The convergence of class speed appears to be low. Carneiro et al. [18] observed that unregistered craniocaudal and mediolateral oblique mammography views had increased the risk rate of breast cancers. The recommended framework is equipped for utilizing the division maps created through mechanized mass and small scale calcification recognition frameworks and delivered precise outcomes. The semi-robotized approach (utilizing physically characterized mass and microcalcification division maps) is applied on two freely accessible informational indexes (INbreast and DDSM). The outcomes concluded that the volume under the ROC surface (VUS) for a 3-class issue (ordinary tissue, benevolent, and harmful) is over 0.9 and the region under the ROC bends (AUC) for the 2-class. CC and MLO mammograms of the Inbreast dataset were studied and explored the minimized false positive rate. Since the appearance and cohesion of the cancerous cells are dynamic, leading to a decline in the performance of classifiers. Zhang et al. [19] stated about the classification of whole mammogram and tomosynthesis images using deep convolutional neural networks approach [19]. An approach of mammogram and tomosynthesis classification based on convolutional neural networks were explored. Here, 2D mammograms and 3D tomosynthesis were used to build a classifier. In specific, transfer learning was used to reuse the information in trained models. The high-quality mammogram data from the University of Kentucky medical center was assessed to investigate the mammogram images. The accuracy rate is greatly enhanced using transfer learning process. The limitation is that the formation of feature

maps in transfer learning challenges the detection of the key elements. Imbalanced data still pertain to machine learning algorithms. Kumar et al. [20] designed a framework based on VGGNet 16, which encounters the benefits of data augmentation, stain normalization, and magnification of the cancer images. CMT histopathological images and human breast cancer dataset was used for study purpose. The system has achieved a 97% accuracy of the systems. Overfitting issues on defining the classifiers increased the false positive rate. Some higher-level discriminating features have slowed down the learning models. Kaur et al. [12] presented the k-mean clustering algorithms, multi-class SVM, and deep neural networks under decision tree models, which enhanced the accuracy of the decision systems. Ten cross-validation models were analyzed using MLP, J48+, and KMean Clustering. The system enhanced the sensitivity and specificity of the designed deep learning models. Region of Interest (ROI) has improved segmentation outcomes. Deep CNN requires a more extensive training model, where a more significant number of decision rules decrease the performance of prediction models. Saha et al. [21] defined that mitosis detection is one of the critical factors in cancer prediction systems. A supervised model was designed using deep learning architecture to overcome the shortages in mitosis detection. It was assessed on datasets such as MITOS -ATYPIA, ICPR-2012, and AMIDA-13. By differentiating between the mitosis and nonmitosis, the increase in the detection rate is observed. The correlation index was less during mitosis prediction. The incompleteness of the histopathological images degrades the pre-processing units with enhanced computational time. The following Table 1 gives a summary of the literature survey.
4 Conclusion In this paper, we have discussed various methods for examining the breast cancer cytological images using the artificial neural network (ANN), and deep neural network techniques. From the analysis, it is inferred that in the examination of histopathological images of breast cancer, MLP and PNN are the most classical ANNs techniques which are widely used. Whereas, along with the classifier, it is analyzed that appropriate feature extraction also plays a significant role as texture features and morphological features are the most widely extracted features from the breast cancer images. Among the deep learning-based techniques, as discussed in the paper, particularly deep convolutional neural networks, has made amazing accomplishments in the detection and classification of breast histopathological images, which will help with early recognition, finding, and treatment of breast cancer.

Abstract. In recent years, the use of Decision-Making Information System (DIS) has become a necessity for monitoring and maintaining a company’s performance. Several studies and contributions have been carried out in various fields. Most of solutions are not suitable for all the areas, and a little attention has been given to research. A lack of DISs is generally noted in doctoral schools (DS). The development of a new decision support methodology (DSM) in research institutions is crucial. This paper aims to determine the predominant performance indicators for handling the overall DS performance. It considers criteria that cover all the definitive stakeholders (DSH) like administration, teaching research staff (TRS), Ph.D. students, and administrative and technical service staff (ATSS). Thus, a research study was carried out regarding DSHs based on collected data from public universities, in Senegal. The DSHs difficulties, and their satisfaction degree have been enlighted. Forty-eight (48) indicators that impact a DS efficiency have been determined. The major criteria for the development of a new DSM in research are analyzed and the main findings are presented in this study. Keywords: Decision-making · Indicator · Performance · Doctoral School · Research
1 Introduction Decision-Making Information Systems (DIS) have become essential for company’s performance [1–4]. Therefore, it is the subject of several works in various areas [4–12]. However, no method can solve all problems and in all areas. But the major problem detected is generally the unavailability of DSM in research for management of the overall Doctoral School (DS) performance [13]. In addition, as pointed out in [12, 13], a literature review on working conditions at the DS level shows that almost all of studies and surveys carried out have focused only on Ph.D. students or, at a pinch, teacher-researchers and supervisors [14–17]. They do not take into account the parameters relating to a DS’ ATSS and Administration. To overcome these limits, a DIS, Decision Support System (DSS) © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2022 V. E. Balas et al.

is important and must be designed for a more complete resolution of the performance DS. Therefore, the identification of situation explanatory parameters is necessary. The main objective of this paper is to define a DS’s performance indicators. These ones take into account the four (4) major DS components, which represent its definitive stakeholders (DSH). This study is carried out on the basis of four questionnaires sent to the DSHs of DS in Senegal. Among approximately 2 980 characters concerned, 378 had then answered the questionnaires. Therefore, the main contributions of this paper are the following: (i) Highlighting the main factors that impact the thesis defense rate and therefore on a DS performance; (ii) Determination of the main DS performance indicators of a DS, taking into account the definitive stakeholders. The remainder of this paper is organized as follows: In Section II, a literature review on DS performance indicators, and presentation and analyze of different investigative approaches available is performed. Then this section is concluded by giving the performance criteria list of a DS detected in the literature. Our approach, devoted to the second Section III, revolves around two main stages: (i) data collection through surveys carried out at the level of the four DSH, with the mixed investigation approach; and (ii) processing and analysis of results using the full-fledged Business Intelligence data analysis tool, Excel. Section IV, identify the performance indicators deemed most relevant from the analyzes performed; indicators that cover the four main components of a DS. Section IV in turn summarizes our contributions. And finally, the document is concluded in Section V through perspectives.
2 Indicators Study for Evaluating a DS Performance: State of the Art 2.1 Concept of Performance Indicator and Research Methods The indicator concept is ubiquitous and widely studied in the literature, in a variety of areas [18–20]. It is defined by the ISO standard as a "numerical, symbolic or verbal expression, used to characterize activities (events, objects, people) in quantitative and qualitative terms (yes / partially / no) with the aim of determining their value" [18, 19]. In other words, an indicator is a meaningful and objective representation that allows us to synthetically measure. Whether or not defined objectives are achieved leads to an interest in the concepts of "performance"; and "performance indicators" (PI). Performance is then relative to the objective’s definition. A structure performance is its ability to implement mechanisms to achieve standardized objectives, well defined nationally and internationally in a given time [18]. PI is widely studied [18–25]. Lorino, 2003 characterizes it as "information that should help an actor, individual or generally collective, to lead the course of an action towards an objective achievement or to allow him to evaluate the result» [21]. In other words, a PI is "quantified data that allows assessing thing

competitiveness in terms of profitability, efficiency and productivity by measurement, over a given period”. In 2019, A. Fernandez underlines that ultimately, PIs help support strategic objectives and check whether the strategy is validated in reality [26]. Mendoza and Al. (2002), identify three essential questions allowing to mark out this strategic reflection: What does the service do? (Action: Train doctors); who are its stakeholders, their expectations and respective contributions (Actors)? What are the expected results? (Objectives) [27]. Figure 1 below is an illustration.
Fig. 1 The indicator’s "triangle": strategy translated into "objective", "action process" and "actor" (collective). Source Lorino (2001, pp 7) https://halshs.archives-ouvertes.fr/halshs-005 84637 Submitted on 9 Apr 2011
There are different types of PI such as key performance indicators (KPIs), (which are those chosen to monitor the service performance). They are of four types: (i) Productivity PIs; (ii) Quality IPs; (iii) Capacity PIs; and (iv) Strategic IPs. But depending on their purpose, there are: (i) Financial IP; (ii) Commercial IP; (iii) Corporate social responsibility (CSR); and (iv) Organizational IP. Characteristics of a good IP are to be: (i) Clear, Objective and Relevant; (ii) Quantifiable (measurable); (iii) Faithful, reliable, and sufficiently "robust"; (iv) Sensitive specific and focused; (v) Informative in its content; (vi) Meaningful and user-friendly; (vii) Timely [23, 24, 27]. Investigation modes are determined by the research paradigms and researcher ambitions. The latter has the choice between three investigation modes: (i)quantitative approach; (ii) qualitative approach; and (iii) mixed approach [28]. Compared to the investigative methods developed, several studies types and analysis of survey data can be used. The most relevant are the following: (i) Exploratory and explanatory studies; (ii) Descriptive and correlational studies; (iii) Correlationalexplanatory studies; (iv) Experimental research; (v) Test research; (vi) Mass research or investigation; (vii) Observational research; and (viii)Applied research [28, 29]. 2.2 Presentation of Criteria for Evaluating a Doctoral School Performance A literature review shows that indicators for evaluating the higher education performance are submitted various organizations like Agency for the Evaluation of Research and Higher Education (AERES), an independent French administrative authority created in 2006 which became the High Council for the Evaluation of Research and

Higher Education (Hcéres) in 2014, United Nations Educational, Scientific and Cultural Organization (UNESCO), Organization for Economic Co-operation and Development (OECD), and others [30–36]. The most relevant for DS are PI proposed in the CAMES Repository-Evaluation-Doctoral-Schools-CAMES (REED-CAMES) produced in 2017 by UNESCO and those expressed in the most recent editions of the OCDE. They are listed below. 2.2.1 UNESCO’s Performance Criteria [31] They concern the following themes and sub-themes: • Organization and operation: (i) Achievement degree of defined missions and objectives; (ii) Institutional relevance of the DS: Coherence of DS missions with those of institutions that carry it; (iii) Staff and students representativeness in decision-making bodies; (iv) Frequency of meetings; (v) Clarity of display of science policy and DS activities; and (vi) Others. • Scientific life: (i) Accreditation rate of national and international DS doctoral programs at CAMES level; (ii) Students admission regularity; (iii) Average duration of theses defended; (iv) Effectiveness of quality assurance measurement, self-evaluation of doctoral programs; (v) Compliance with the rules and standards for the theses supervision; (vi) Organization level of scientific events; (vii) Accessibility of complementary, diversified and credited training (seminars, conferences, teaching) for Ph.D. students; (viii) Degree of contact between Ph.D. students and the professional world; and (ix) Others. • Outreach and attractiveness: DS’s ability to make itself influential on the international level: (i) Degree of international openness of the DS; (ii) Quality and duration of partnership relationships; (iii) Selectivity and importance of national and international events; (iv) Contribution degree to the dissemination of scientific culture; and (v) Others. • Resources: means available to the DS to ensure its functioning, management and scientific and educational activities: (i) Quality and condition of pedagogical equipment and tools; (ii) Scientific productions quality (papers, books, and Others.) drawn from the theses defended; (iii) Qualification and sufficiency of administrative and technical staff; (iv) Qualification and sufficiency of teaching and research staff responsible for doctoral supervision; (v) Existence of sustainable, sufficient and predictable funding: DS budget. • Organizational and scientific perspectives: (i) Skills and resources availability; (ii) Coherence degree of the new trainings (seminars, workshops, courses, and Others.) with regard to the new DS objectives; (iii) Engagement degree of new partners: Presentation of partners, and (iv) Others. 2.2.2 OECD Performance Criteria • The OECD performance indicators listed cover the following themes: • Results of educational institutions and learning impact: (i) Percentage of graduates per age group; (ii) Rate of tertiary teaching graduates; (iii) Influence degree of training level compared to the employment rate; and (iv) Others [32].

• Financial and human resources invested in education: (i) Annual expenditure rate of institutions per pupil / student, per service type, from primary to tertiary teaching [33]; (ii) Percentage (%) of GDP for education; (iii) Tuition fees rate in relation to the percentage of recipients of study loans, scholarships or grants; (iv) Breakdown of operating expenses of primary, secondary and post-secondary non-tertiary education establishments; and (v) Others. • Access to education, participation, and progression: (i) Enrollment rate per age group; (ii) Rate and profile of new entrants in tertiary education; (iii) Rate and profile of tertiary education graduates; (iv) Rate, profile and professional outlook of Doctorate holders; and (v) Others [34]. • Learning environment and school organization: (i) Supervision rate and class size; (ii) Teacher salary level; (iii) Rate of qualified Research Teaching Staff; (iv) Evaluation systems rate for teachers and Establishment heads; (v) Existence of key decisionmaking systems in education systems; and (vi) Others [35]. Faced with a set of investigation and study methods presented, to meet this mission of characterizing performance indicators for a DS, the mixed approach is the most appropriate, with the use of mass research or survey.
3 Survey Procedures and Analysis of Results This part presents the procedures used to achieve this study’s purpose, from the survey to the results analysis. In this context, based on the guidelines defined by the Ministry of Higher Education, Research and Innovation (MESRI), requests that the DS themselves had defined, but above all those requested by the DS’ actors who intervened in the investigations, are maintained the specific objectives, as follows: • Ensure good and efficient governance and the DS organization; • Preserving and strengthening satisfaction in material and immaterial administrative infrastructures; • Manage and guarantee the sufficiency of material and immaterial research infrastructures; • Propose timely initiatives. This study process consists of two main steps: (i) data collection and (ii) analysis of the results obtained. 3.1 Data Collection To achieve this, a strategy for collecting and studying survey information is carried out with four (4) questionnaires. These surveys were performed on ten (10) DS, representative of those in Senegal, namely: • The seven (07) DS of Cheikh Anta DIOP University of Dakar (UCAD): (i) “DS of Arts, Cultures and Civilizations” (ED ARCIV); (ii) “DS of Water, Quality and Uses
Determining Key Performance Indicators for a Doctoral School
29
of Water” (EDEQUE); (iii) “DS of Studies on Person and Society” (ED ETHOS; (iv) “DS of Legal, Political, Economic and Management Sciences” (ED JPEG); (v) “DS of Mathematics and Computer Science” (EDMI); (vi) “DS of Life, Health and Environmental Sciences” (EDSEV); and (vii) “DS in Physics, Chemistry, Earth, Universe and Engineering Sciences” (ED-PCSTUI); • The two (02) DS of Gaston Berger University in Saint Louis (UGB): (i) “DS of Science and Technology” (EDST); (ii) “DS of Sciences on Person and Society” (ED SHS); • The Doctoral School of Sustainable Development and Society “(E2DS) of University of THIES. They are addressed to the four DSH of Senegalese DS (Administration, TRS, ATSS, and Ph.D. students). 3.2 Results Analysis Processing and analysis of results is performed using the full-fledged Business Intelligence data analysis tool, Excel. It is accompanied by a commentary on impacts DS performance. The main themes addressed in this study are the followings: (i) Characterization and presentation of concerned population; (ii) Working modalities and quality of services; (iii) Research and work arrangements; (iv) Funding; (v) Theses and defenses. The investigation covered all the components of the ten Senegalese DS selected. It reached a target population of 1618 Ph.D. students, 1342 Framers and teacher researcher, 10 ATSS, and 10 Directors. Or a total of 2980 asked. However, the number of returns on the questionnaires distributed, as presented in Table 1 below, only corresponds to: (i) 320 among Ph.D. students; (ii) 44 from Framers, Supervisors or Teaching Research Staff; (iii) 5 from the Administrative and Technical Service Staff (ATSS) and (iv) 8 from Directors. That is to say a total of 377 respondents. This makes an overall participation rate of 12.65%, better exposed on Table 1. An overall participation rate not very satisfactory, in particular on research professors and supervisors with whom, among 1342 requests, it is only obtained 44 responses, i.e., a rate of 3.28%. This testifies and reveals the difficulty and delicacy of the collection phase. Statistics for Supervisors are not determined per DS in this table because a teacher and Framer can be from multiple DS. This table reveals that the Ph.D. students are unevenly allocate in DSs. All the DSHs were represented. But at UGB, only the EDST Director came back to us. At UCAD, the ED ARCIV secretary and the ED ETHOS Director at the time, did not respond to questionnaires even after several requests. • In addition to 65% of Ph.D. students who state that they do not have an information platform, the non-availability of classrooms and defense lecture halls, the lack of programming and information in time, is source of problems for following modules among 42.1% of Ph.D. students. It would therefore be interesting to offer the possibility of taking distance courses in order to allow Ph.D. students outside Dakar or unavailable to attend; but above all to implement new websites, regularly updated to: (i) Access information in time; (ii) Download documents and forms as needed; (iii) Archive and access DS articles and theses.

• The rare participation of Ph.D. students in seminars requires a more frequent organization of these scientific activities, but in particular of doctoriales by each DS with new initiatives: (i) Mandatory participation of the Ph.D. student before being able to defend the thesis; (ii) Involvement and presence of teachers and framers; (iii) Publication in an international journal of the best works; (iv) Ph.D. students motivation by a prize-giving ceremony, for the best; (v) Greater involvement of the socio-professional world. • Several phenomena are the cause of a long duration of thesis preparation, among which: (i) 60% of responding Ph.D. students are in “Professional activity”; (ii) Among women, 19.55% have children; (iii) The funding lack of 69% and subsidies is the source of the blockage for publications, since most journals are chargeable; (iv) A high number of framing that exceeds the standards (more than 10) on the part of the Supervisor; (v) Theses interruptions due to several factors; (vi) The low equipment level of research structures underlined by 66.46% of Ph.D. students, supported by the TRS and witnessed by almost all DS Directors; (vii) Late payment of jury members; (viii) failure to cover external jury members • The financial problems suffered by the Ph.D. students and Supervisors are deplored by the ATSS (which does not receive compensation from DSs), but especially by the DS Directors who do not manage to meet the needs of their institute in material and immaterial infrastructures on time, to meet the expectations of the other three DSHs and therefore not to achieve their objectives; financial management lack of Senegalese DSs by the Rectorate. The performed analysis reveals that this dependence of almost all DS in Senegal from the Rectorates is not limited to a financial plan but is also administrative. These institutes have an ATSS deemed insufficient by the Directors, due to an availability lack

of financial manager, mail agent and even administrative assistant. Defense rooms are not available; Senegalese DS do not have a defense amphitheater. But the number of Ph.D. students able to defend thesis per year, given by the Directors, varies from one DS to another. And these figures are just approximate. This is why it has been found it appropriate to strengthen and complete our research with a second expertise. This One is established from exact data and statistics, taken at the source, in order to have confirmed and decisive information. This investigation is being carried out at the level of a university in Senegal: Cheikh Anta DIOP University of Dakar (UCAD). This choice is justified by the fact that it represents the largest University in Senegal and one of the largest in Africa, and thus brings together a very large number of students, of many nationalities. In addition, 70% of DSs on which our research relates are lodged there. The studies carried out therefore focused on: (i) a promotion of students registered in the first year in 2011, who arrived in doctorates (an examination which goes from cycle L to cycle D); (ii) all Ph.D. students who must defend their thesis and Doctors trained in 2018. They reveal us that on the one hand, among 29,134 students enrolled in the first year, 1,089 pass the M cycle to enroll in a Doctorate; i.e., a rate of 3.74%. On the other hand, they reveal that among these 29,134 registered students, 11,315 are female gender; i.e., a rate of 38.84%. And better still, it shows that of these 11,315 students enrolled in a Senegalese public university, 400 i.e., a rate of 3.53%, are enrolling in a doctoral thesis; Which is contrary to Objective N° 5 of Sustainable Development Goals (SDGs) by 2035 for a country (Gender equality). However, this rate is almost equal to the average; hence the need to encourage research among women. This represents an interesting discovery for donors, funders, and international organizations such as UNESCO. This low rate of students entering cycle D means two things: • Either students are not at all interested in the doctorate; • Either the success rate of Master students is low: which shows a performance lack in the L and M cycle; and therefore, has its impact the D cycle. This UCAD promotion of 2011, which enters the first year of a thesis in 2015–2016, is followed along with all those registered. Analysis of results shows us that among 2377 Ph.D. students enrolled in 2017–2018: • Total number of Ph.D. students totaling three (3) or more registrations (i.e., “who had to defend their thesis”) is 1975; i.e., an overall rate of 83.08%. Among the latter, those of the “Feminine” gender are 516; or 26.12%; • Total number of Ph.D. students who have defended at the end of 3 years is 19; or an overall percentage of 0.96%, of which 4 are Female Gender; or 21.05%. Among 100 Ph.D. students able to defend their thesis, 0.77 support their thesis on third registration (after 3 years); • Total number of Ph.D. students who have defended at the end of 4 years is 44; or an overall percentage of 2.22%, of which 9 are female Gender; or 20.45%. Among 100 Ph.D. students able to support their thesis, 1.74 defend after four registration;

• Total number of Ph.D. students who have defended at the end of 5 years is 57; or an overall percentage of 2.88%, of which 11 are female gender; or 19.29%. Among 100 Ph.D. students able to defend their thesis, 2.13 support in five years; • Total number of Ph.D. students who have defended at the end of (AEO) 6 years is 41; or an overall percentage of 2.076%, of which 14 are female gender; or 36.58%. Among 100 Ph.D. students able to support their thesis, 2.90 defend on their sixth registration; • Messed up theses (failed) constitute those of Ph.D. students registered more than six (6) times (who have not defended their thesis after 6 years. Even if the Ph.D. student returns one or two years later to defend, his thesis is considered messed up.). This study shows that 101 theses are failed; or an overall percentage of 5.11%, of which 26 are female gender; or 25.74%. This reveals that the total number of Ph.D. students having defended compared to the 1975 who should defend their thesis in 2017–2018 at UCAD is 200; i.e., an overall rate of 10.13%. These results are better presented for each DS in Table 2. By categorizing this study, results in Table 3 are obtained and presented. The results from Table 3 show on the one hand that those who support at the end of three (3) years are often, at 69% less than thirty-five (35) years old. So, they are single people without children and not in professional activity (PA). And on the other hand, that those who support at the end of six (6) years or have been victims of messed up theses, are in 70.3% over thirty-five (35) years old; So, they are often married with children, and especially among women. In addition to a family to take care of, the ladies are in PA. This shows once again that the factors “marital status”, PA, and financing have a great impact the Ph.D. students success. A study over four (4) years of theses defended at the DS level shows us that it is the same framers who complete the theses of their Ph.D. students on time and that the same ones once again drag up to five, six years or screw up those of their students. In this context, it is given the example of a teacher researcher who: (i) Before going to the class “Professor” had 9 Ph.D. students supported on time; 2 at the end of 5 to 6 years; 1 messed up; (ii) Become a “Professor”, had 2 Ph.D. students supported on time; 11 at the end of 5 and 6 years; 3 messed up thesis. The reason is that it was demanded of them. So, teacher researchers do half the number of theses defended on the time when they become tenured. So, the motivation of supervisors and framers has a big impact Ph.D. students success. At this stage, it can be proceeded to the specification of the decisive indicators for the performance of a DS.
4 Determination of Performance Indicators for a Doctoral School In this section, a sampling of the main performance indicators deemed to be the most relevant will be carried out.

relevant are defined on the basis of the analysis carried out; which makes the originality of the adopted strategy. They cover the four major components of a DS. The specified indicators must meet the SMART criteria (Specific, Measurable, Achievable, Relevant and Time-oriented) and are forty- eight (48) in number. Depending on thematics, the criteria retained in this research work are listed below: 4.1 Doctoral School Governance 4.1.1 Organization (1) Constitution of decision-making bodies. It is an important performance criterion that influences decision-making, and therefore the governance of a DS. It is measurable by the percentage, appointment and presence of Ph.D. students’ representatives, TRS, and ATSS on the Scientific and Pedagogical Council (SPC) of DS; (2) Existence (Yes/No) of an admission campaign for Ph.D. students; This is a good indicator for recruiting Ph.D. students. It is also very important given the marketing aspect to develop; (3) Existence of an admission system for Ph.D. students (Yes / No); indicator that facilitates the task; (4) DS training accreditation rate at CAMES and national quality agencies: Important indicator for the DS training initiative. 4.1.2 Research and Work Facilitation Devices (1) Regular holding of meetings: Average rate per number. This indicator is convincing in the context of the participation of DSH in decision-making; (2) Regular website update. It is a fundamental cross-cutting indicator. It can be measured by the rate of satisfied or from the last access of the administrator including: (i) Information and procedures for the selection and evaluation of Ph.D. students; (ii) “Adequacy of conditions for managing Ph.D. students’ registrations and files: (3) Existence of an archiving system for thesis defense. It is an interesting indicator of the performance or otherwise of a research institute. It allows on the one hand, to have the number of defended theses with all the corresponding information, and on the other hand, the availability of specialized bibliographic resources. It thus facilitates bibliographic research for Ph.D. students preparing their thesis, and helps to avoid or reduce the possibilities of plagiarism; (4) Availability of business intelligence systems or models. It is an essential indicator for evaluating and managing the performance of a service. This, by helping to make adequate decisions when faced with a problem. 4.1.3 Financial Management (1) DS administration financial reports. This is a decisive indicator for having transparency in the management of financial resources in order to know the decisions to be made regarding the use of the budget;
36
A. Kane et al.
(2) Rate of financing of the DSH material needs and scientific activities. This is an indicator for estimating the DS’ level of equipment» and support for scientific and research activities; (3) Level of compensation for thesis jury members. Determining indicator which impacts the motivation of the PER and the supervisors and consequently on the number of theses defended. (4) Payment of thesis allowances on time and support for external jury members. This is an influential indicator, which has an impact whether or not theses are held; therefore, on the number of theses defended. It is measurable by the % of paid on the thesis defense day; (5) Fairness and equity in personnel management in relation to responsibilities: ATSS motivation indicator that impacts the work progress; (6) Substantial granting of compensation to ATSS: Motivation indicator for ATSS, influencing the DS performance. 4.2 Satisfaction with Material and Immaterial Infrastructures 4.2.1 Working Methods: Training, Supervision, Administration (1)

Internet connection infrastructure in DS premises. It is essential for administrative work and research. It can be measured by good accessibility to network (throughput); Qualified Administrative and Technical Service Staff (ATSS) / Ph.D. students rate. This indicator is eminent insofar as it gives an idea of the number of Ph.D. students attended by an ATSS; which expresses the sufficiency or not of the ATSS responsible for Ph.D. students; Satisfaction on the secretariat of the help with administrative procedures. This is a considerable indicator as it impacts the number of registrants. It is measurable by the percentage of satisfaction with the secretariat (Ph.D. students, TRS, visitors); Rate of Teaching Research Staff (TRS) authorized to supervise research work (Researchers of masterly rank, Professors, Lecturers and Research Masters CAMES) / “Ph.D. students enrolled”. This is a fundamental indicator which gives an idea of the number of Ph.D. students in supervision per TRS; therefore, the number of Ph.D. students per unit of TRS. Therefore, it helps to measure whether or not the framing rules and standards are respected. It also gives a better view of the “rate of TRS authorized to supervise” remaining; Framer availability. The importance of this indicator is explained by its influence on thesis duration of Ph.D. students. It is measurable by the number of work sessions/month; Rate of Ph.D. students per unit of local. This indicator measures the availability of premises in relation to the total number of Ph.D. students. Its importance is also justified by its direct impact the duration of Ph.D. student’s thesis; Equipment level of premises: (machines, IT equipment and supplies, office equipment and furniture, availability of: “logistical means (vehicles)”, and others). The relevance of this indicator is demonstrated once again by its direct impact the tasks duration to be accomplished by the ATSS, the TRS and on the duration of

Ph.D. students theses, and therefore the graduates rate. It is measurable by the percentage of Satisfied with the equipment; Organization frequency of diversified additional training, for Ph.D. students or employees (seminars, workshops, conferences, capacity building for ATSS, and Others.). This good criterion allows to measure the scientific activities development from the number organized; Participation rate in scientific events: This is an interesting indicator that provides an opinion on the success of scientific activities. It is measurable by: Favorable responses (presence of people who are references in the field (at least 2); Presence of TRS and Ph.D. students: 50 to 100%; national and international participation) or Satisfaction of the organization; Rate of DS partnership with spinoffs (advantages) for the socio-economic development of the country: decisive indicator for access to diversified financial resources; International openness degree of the DS: This is an appropriate indicator that can be measured by many criteria such as: (i) the rate of foreign Ph.D. students received, the rate of co-supervision, the granting of open training (s), (ii) the rate of DS partnership with national and international research structures; (iii) the proportion of Ph.D. students participation in national and / or international activities, (iv) the research projects quota funded at the international level, (v)the rate of Ph.D. students awarded at national or international level, (vi) the Ratio “Number of indexed publications in international journals. The success of scientific activities is a good indicator of the international openness degree of a DS; Quality of the supervision methodology: Important indicator measurable by: (i) Participation degree of Ph.D. students in the life of research structures: measurable by the number (list) hosted by each of the research structures; (ii) Existence of a monitoring mechanism for the research work: (DS internal regulations; Document presenting the monitoring mechanism; Meeting minutes of the monitoring mechanism); Frequency of presentation sessions for Ph.D. students: Indicator, influencing the progress of the Ph.D. students’ thesis and thus on the number of theses defense; Availability of teachers per modules: Important indicator for monitoring modules.
4.2.2 Financial Resources (1) Existence of a sufficient and predictable budget. Essential criterion for the DS performance. It is measurable by the availability through Educational Registration Rights; the distribution percentage and the management report; (2) Diversified financial resources: This is an influential indicator, which can be measured from: (i) research contracts, the provision of expertise or resources, (ii) support for the organization of scientific projects or activities, (iii) donations from individuals obtained with or without academic partners, (iv) funding mobilized for thesis work, and (v) Others.

4.3 Results of the Defenses and Prospects of a Doctoral School 4.3.1 Theses Defended: Graduates (1) Duration of thesis preparation: Important indicator of the specification of a DS’ performance. (2) Rate of publications in ISI indexed journals / Ph.D. student. It is a fundamental performance indicator as it advises on the international openness degree of a DS and gives a good idea on its effectiveness; (3) Rate of theses defended at the end of three (3) years compared to the “Rate of registrants able to support their thesis” according to the: (i) Nature (or source) of funding (Fellows and Ph.D. students in PA); (ii) Marital status (Married with children); (iii) Number of theses supervised by the framer; (iv) Laboratory equipment level; (v) Interruptions during the doctoral course; (4) Rate of theses defended at the end of four (4) years compared to the “Rate of registrants able to support their thesis” according to the: (i) Nature (or source) of funding (Fellows and Ph.D. students in PA); (ii) Marital status (Married with children); (iii) Number of theses supervised by the framer; (iv) Laboratory equipment level; (v) Interruptions during the doctoral course; (5) Rate of theses defended at the end of five (5) years compared to the “Rate of registrants able to support their thesis” according to the: (i) Nature (or source) of funding (Fellows and Ph.D. students in PA); (ii) Marital status (Married with children); (iii) Number of theses supervised by the framer; (iv) Laboratory equipment level; (v) Interruptions during the doctoral course; (6) Rate of theses defended at the end of six (6) years compared to the “Rate of registrants able to support their thesis” according to the: (i) Nature (or source) of funding (Fellows and Ph.D. students in PA); (ii) Marital status (Married with children); (iii) Number of theses supervised by the framer; (iv) Laboratory equipment level; (v) Interruptions during the doctoral course; (7) Rate of messed up theses (having lasted more than 6 years) compared to the “Rate of registrants able to defend their thesis” according to the: (i) Nature (or source) of funding (Fellows and Ph.D. students in PA); (ii) Marital status (Married with children); (iii) Number of theses supervised by the framer; (iv) Laboratory equipment level; (v) Interruptions during the doctoral course. These are decisive result indicators, presented as a ratio between primary indicators. They make it possible to measure the success rate of Ph.D. students, the average duration of theses defended, and the rate of theses having failed, according to a set of criteria. Therefore, they give an idea of decisions to be taken to remedy problems and ensure a good performance of the institute. (8) Thesis defense rate / framer given. It is an interesting indicator which gives an idea of the PV and the progress of the teacher-researcher. 4.3.2 Objectives and Perspectives of Operation and Evolution of a Doctoral School (1) (2) (3)

Time percentage of management profit and independent financial availability: Timely response to the infrastructure needs of all stakeholders; Subsidy and even funding for Ph.D. students; Payment of thesis jury members on time; Granting of compensation to deserving ATSS, Organization and financing of scientific activities; (5) Percentage of productivity of training created over time; (6) Advantages of work platforms for efficient programming and calculations; (7) Percentage of profit from the establishment and compulsory follow-up of a course in “Thesis methodology”; (8) Percentage of profit from the presence of supervisors and Ph.D. students at doctoral studies; (9) Percentage of interest time of a DIS. These are appropriate criteria which give an idea of the degree of a DS evolution. (10) Development degree of the institute. With the rapid evolution of training and research needs in new fields, a DS must adopt new alternatives. In addition to the above-mentioned outlook indicators, the number of programs or streams created, substantially modified or closed, and the average duration of new programs creation, on an annual basis, are considerable indicators of development degree of an institute.
5 Discussion To determine the performance criteria of a DS, a study of indicators relevant to this context, existing in the literature, was performed. Thus, those submitted in UNESCO’s REED-CAMES are listed with those from the most recent OECD editions; which allowed for a substantial collection of indicators. As the latter are not yet systematized for a SIAD, several convictions arise: a limit to be regulated. Therefore, suitable indicators, meeting the expectations of all DSHs of a DS are necessary to be determined. In this context, surveys concerning the four major components were carried out at the level of the ten largest DS in Senegal. The analysis of these surveys results allowed us to examine a set of questions and to discover several realities. In addition to these innovations, a second expertise with exact data, taken at source, is carried out for reinforcement. It concerns a university promotion (of UCAD - 2011, arrived in Doctorate in 2015), and the Doctors rate trained three years later (in 2018). Analysis of this data revealed accuracy. It is shown that: • The thesis defense rate in three (3) years is 0.96%; too low percentage. It is AEO four (4) years, or even five (5) to six (6) years that that there is a Doctor rate of 2.22; 2.88; and 2.076%; This witnesses that the regulatory deadline for a thesis set at three (3) years is short for Senegalese Ph.D. students; hence the need to increase it. • However, it should also be noted that the thesis preparation duration as well as Ph.D. student’s success rate and thus that of DS performance do not totally depend on the deplorable factors with which DSHs are confronted but also on the DS’ organization and serious in work. This is firstly proven by the higher Ph.D. students rates able
40

to support in literary disciplines, while the thesis defense rate is higher in scientific fields. This, as well at the end of 3 years, 4 years, 5 years as at the end of 6 years. And in return, by a higher rate of messed up theses in these literary fields; Confers Table 3. The factors and criteria that impact a DS performance, deemed to be the most relevant and consistent are as follows: (i) Sufficiency of ATSS and TRS, financial autonomy, availability and equipment of premises, holding of a course in "Thesis methodology" at the DS’ level, organization of DSs in the work, relations with internal or external cooperation, integration of the SPC in decision-making, provision of a DIS; (ii) The marital status, professional activity, and funding of Ph.D. students; (iii) improving the title of research professors, the maximum number of Ph.D. students to follow, the level of compensation and the on-time payment of jury members and the supported for externs; (iv) additional training, compensation for ATSS; (v) the regulatory deadline for a thesis, and (vi) others. They constitute parameters that have a direct impact the thesis defense rate during the year, and therefore a DS performance.
6 Conclusion and Future Works In order to achieve this study’s objective, one of the greatest contributions of this study consist in the discovery and demonstration of the main factors which impact the thesis defense rate, and therefore, the DS performance. Faced with the situation, it is proposed: Firstly: • An increase in the regulatory deadline for a doctoral thesis in Senegal to four (4) years. This represents an important decision for a DS performance because the thesis in three years in Senegal is a “chimera” given: (i) the gaps that students here have from cycle L to cycle M; (ii) Ph.D. student must be empowered to become an expert in his field, and not of his subject; (iii) Senegal’s working conditions, as demonstrated, are far from being met; • A revaluation and harmonization of the level of compensation for jury members: Fundamental and motivating initiative for PER, which develops thesis defenses and thus the number of doctors trained; • A decisive granting of indemnities to the ATSS: Act encouraging them to better respond to their duties and tasks; • Autonomous financial management: This will allow Directors to meet the expressed needs and thus, satisfaction of the DS DSHs; • Better organization of DS at work. On the other hand: the implementation of a tool to overcome the identified factors. This is the subject of our future work. How? ‘Or’ What? A new decision support methodology in this direction: a Prospective Dashboard [27, 37, 38] is proposed, based on a choice of the preponderant indicators for the DS’ performance, on those determined [24].

Cloud Attacks and Defence Mechanism for SaaS: A Survey Akram Harun Shaikh(B) and B. B. Meshram Department of Computer Engineering, Veermata Jijabai Technological Institute (VJTI), Mumbai, India {ahshaikh_p18,bbmeshram}@ce.vjti.ac.in
Abstract. Cloud computing systems are the de-facto deployments for any user data and processing requirements. Due to a wide variety of cloud systems available today, increase in the number of services provided by these systems. These services range from software-based systems to high-end hardware-based infrastructures. The wide variety attracts a lot of attention by unwanted hackers, due to which the cloud deployments are one of the most cyber attacked entities here, we review the attacks and issues of cloud computing entities namely Software as a Service (SaaS). These attacks are quantified at both micro-level and macro-level. This paper also discusses the different solutions for these attacks, identified the gaps of each solutions and recommends methods which can be adopted to further improve the discussed solutions. Keywords: Cloud · Attacks · IaaS · PaaS · SaaS · Solutions · Deployment
1 Introduction The number of attacks is ever-increasing in the cloud. This is due to the fact that more and more businesses and customers are shifting from local server-based deployments to cloud deployments. Due to this fact, cloud deployments have become a playing field for penetration testers, white-hat hackers, black-hat hackers and other security personnel [1]. These attacks can be software-based, platform-based or infrastructure-based. Softwarebased attacks can attack SaaS, PaaS, and IaaS deployments, while platform-based and infrastructure-based attacks usually attack only the PaaS and IaaS layers, respectively. In order to summarize the list of attacks that can affect on each of these cloud layers, researchers can refer Fig. 1a as follows, To remove these attacks researchers from different domains have suggested different techniques [2]. For instance, to remove SQL injection and XSS attacks; techniques like regular expression matching, deep learning-based classification and others. In order to remove different kinds of attacks, different kinds of approaches are needed; these approaches differ in terms of computational complexity, time complexity, algorithmic complexity and other levels of complexities. It is very difficult for researchers to evaluate each and every method manually, and then apply it for their own research [3]. Thus, in order to resolve this issue in this paper SaaS attacks and their defense mechanisms have © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2022 V. E.

been studied and identified. These mechanisms allow the researchers to identify the best practices in each of these domains and then select the ones which are better for their particular application. Moreover, in this paper we have also identified about different cloud architectures and their components. The following Fig. 1b. showcases these components, This text also covers the security aspects of this component. At the End, we conclude this paper with some finer observations which are made specifically to cloud security, and how to improve the performance and security level of this work with the help of more complicated computational structures.

2 Cloud Issues Attack and Defence Mechanism 2.1 SaaS Security Issues SaaS-based cloud architectures have different components like web browsers, web server, database server, etc. Each of these components has their particular security challenges in cloud. These security challenges often tend to singularize into general components. From a detailed comparative study about these components done in [1], wherein the authors have mentioned challenges and issues of cloud like data loss, issues in transparency, issues in virtualization, issues in Multi-Tenancy and Managerial Issues. Wherein the loss of control issues includes but are not limited to loss of data & data breach, regional considerations during data transmission and storage, low cost data sources & data analytics. Due to these data control related issues, components like web browsers have to be closely monitored by governing agencies, so as to make sure that no data is being compromised from them. Moreover, other components like web server are also susceptible to data breaches, wherein the attacker might not get access to the actual data, but can get access to patterns in the data, which in turn leads to privacy issues from the user’s perspective. Lack of transparency issues are generally to deal with the data provision intentions of the cloud service providers. Governing agencies ask for user specific data whenever a red-flag is triggered. In the presence of such a request, it is the duty of the provider to be transparent and share full details with the asking authority. But, due to managerial or user-based disclosure issues, the cloud providers do not share this information, instead feed incorrect or non-appropriate information. There by raising transparency issues within the cloud. In order to solve these issues, authors have mentioned techniques like encryption of data, providing access control rules, auditing data integrity using 3rd party auditors, physical and virtual isolation of the cloud deployment, software-based trust establishment techniques. Wherein trust-establishment algorithms [2] like relationship management, trust-packets, etc. have been proposed by researchers

over the years. A second variety of trust-based solutions are hardware-based trust solutions [2], wherein researchers claim to be using hardware chips in order to establish trust among common-hardware devices, thereby reducing the chances for attack. Moreover, government agencies can setup rules in order to further extend the security of cloud. The rules setup by the government agencies apply to a very wide range of audience thereby it is recommended that Government must employ public interest rules in order to further strengthen the presence of cloud deployment in a particular geography. 2.2 Cloud Attacks and Defence Mechanism for SaaS The following Table 1 summarizes the different kinds of attacks, their solutions, and Identified gaps in each defence mechanism and other details for SaaS-based cloud systems, Table. 1 Componentswise Classification of Cloud attacks and its Defence mechanism SaaS Component

From the above table we can understand that different attacks have different security algorithms, and due to their mutual exclusivity, these algorithms can be applied in a hybrid manner for any cloud deployment. Attacks like denial of service (DOS) also affect all kinds of SaaS deployments, a software defined network (SDN)-based algorithm to counter the DOS attacks in SaaS is described in [41], wherein algorithms like sFlow which is a part of the OpenFlow protocol is used. This protocol allows for mapping of IP addresses, ports and MAC addresses in order to gather incoming and outgoing traffic statistics from routers and cloud servers. The SDN allows for an efficient implementation of cloud layers, thereby helping in identification of malicious packets which might be causing the DOS attacks. The proposed solution uses a monitor, an analyser, an external mitigator and an internal mitigator in order to identify mis-behaving users/IPs. There are certain security policies in place, which enable for an effective DOS attack detection. The proposed SDN solution can also be used for honey pots and other intrusion detection systems. Virtual private networks (VPNs) which are a major component of SaaS-based deployments, are gaining a lot of popularity due to the high level of anonymity provided by them. A detailed description of attacks and vulnerabilities for VPNs is described in [42]. VPNs are susceptible to all kinds of attacks which include, MIM Attack, Impersonation attack, attacks on Browser, attacks on SSL, Denial of Service (DoS), Eavesdropping, Session Hijacking attacks, Replay attack, attacks on Password discovery and Reflection Attack. A general approach to reducing these attacks is also described in [42]. Solutions to these attacks are similar to solutions for any other software component, and include encryption, trust-establishment, isolation, etc. as described previously.. Another review on the cloud security process is described in [43], wherein database, website and other software component related attacks like injection attacks, XSS attack, CSRF attack, protected APIs, Cookie poisoning, Hidden field manipulation, Backdoor and debug option, Broken authentication and session management, Broken access control, Sensitive data exposure and other SaaS issues with their probable solutions are defined. The work in [43], can be kept as a benchmark for further evaluation of these issues and solutions. Two more Authors on SaaS security worth mentioning are the work done in [44, 45]. In [44], the researchers use block chain for security SaaS services. Block chain is a preferred method for cloud security due to the fact that both block chain and cloud are distributed, can support peer-to-peer architectures, use high performance nodes, and reward users-based on their involvement in improving the system’s efficiency. From the work done in [44] the researchers have analysed that adding block chain-based algorithms and integrity of the cloud platform exponentially without adding overheads to the system. While block chain is found to be promising, its real time implementation and scalability will always be a concern looking at the Bit coin example, where the computational complexity is so high, that nowadays its not recommended to mine the bit coins. But, deep learning and machine learning-based security algorithms as mentioned in [44] have proven to be both computationally efficient and highly secure. Thus, there is a need to integrate machine learning algorithms with block chain to improve security of the entire cloud SaaS system.

3 Conclusion and Future Work From this paper we can analyse that the cloud systems and its components face a wide variety of security issues. These issues can be resolved by using strong authentication techniques (like identity-based authentication, attribute-based authentication, etc.), strong cryptography systems (hashing, BLS, etc.), strong physical systems, strong attack detection & removal algorithms, and strong techniques for other parameters. Strong in this case means algorithms & techniques that satisfy the cloud’s QoS requirements along with the security requirements. This paper has listed the various component of a Cloud system for SaaS like web Application Server, web server, database server etc., that comprises of SaaS. This paper is also categorized the different attacks on each component of SaaS. This paper has also put focus on the various defence Mechanism of each attacks and identified various limitations and gaps in each solutions of respective attacks to the cloud application.

1 Introduction Now-a-days Social media is a tool that became more popular and even became a part of people’s life. Due to its user-friendly features the people are even more attracted to use them. If we need to say a single sentence to describe Social media then we can say that the entire world was in our hand at just a single click away. One of the foremost dominant users of social media are the youth. There were many other negative and disadvantages of social media usage but it was very less compared to the positive aspects. When we consider the positive things in this field, we can observe many advantages. The first and the most prior one was education. By social media platforms we can learn many things. All the aspects that we need were just a click away. Even we can find live lectures in social media examples where a university professor was giving a lecture by sitting in his/her office and the students or the people who are interested in listening can easily listen by just sitting at their individual residences. Even when we consider the current situation of decrease in newspaper reading, more people left the newspaper reading due to the high usage of social media platforms as it gives the news that was happening in the world instantly which cannot make the people wait for the next day to know what actually happened at that situation or place. Social media made people not to think that distance isn’t any problem because due to social media it made people connect with each other that they were very close with.

people to always connect with their closer ones, relatives and friends for ever even if they were not near to them. When compared to the employees or elders, University and College students are the most users that are using Social media platforms more effectively. Because social media is the only platform which gives entertainment, facts, study and many other information they need in an efficient manner and at a single place. They can observe their role model how he/she was leading their lifestyle in their official social media handles, so these types of many similar things are attracting the students and the youth to these type platforms. Social media can also be used as a biggest asset for learning something from others and getting motivated. These types of things can help people to socialize in society and help in choosing the right paths in their life by seeing their role models. Social media can even make new bonding with other people and they can connect with their stream experts and start engaging with them to learn something new or to clarify their doubts. Now-a-days social media are also used as a marketing platform for many products which helps the consumers to reach their product directly to the customers. This way these social media platforms are even helping some of the marketing agents to get jobs.
2 Related Study In pandemic situations, students are facing a lot of difficulties in discussing with their friends regarding their assignments, tasks, projects, and many more. We have many platforms for attending classes online and many applications for chatting and video calling with friends and we also have many platforms like Instagram, Facebook, LinkedIn for knowing the updates regarding many things including entertainment, news, sports, and so on. But we don’t have a particular dedicated platform for discussing with our friends regarding our assignments and our tasks are given in our academics and posts for different college events, experiences and placements events, etc. We have specially dedicated platforms for jobs, careers, entertainment, chatting, online classes but we don’t have one for students’ purposes like knowing about events, placements, exams, hackathons happening inside or outside of their institute [1]. In Fig. 1, it describes the count of people using social-media concerning years. we can see most of the people use Facebook because teens, adults, old age people get attracted and spend most of their time using Facebook. In the list next comes, YouTube and then, WhatsApp, Instagram, etc. we can observe the day-by-day users of social media getting increased from the above comparison. The Fig. 2 represents the different age groups on the different social media platforms. By looking above, the bar chart we can say older teens are more active on social media compared to young ones. Now, the question that is in everyone’s mind, does social media harm students? If Yes, then how to make a social media platform completely advantageous to Students. 2.1 Security in Social Media Some applications are specific for sharing posts related to fun or jobs etc. like Instagram, Facebook, LinkedIn for knowing the updates regarding many things including

entertainment, news, sports [2, 3]. One can only share their posts related to the fun but, not related to college events, experiences at interviews, etc. These drawbacks made us think and come up with a new idea by giving them a separate platform for having all of these thing. The Fig. 3 represents the most security breaches in current social media platforms [4–6]. Whenever a social media site is developed people are highly concerned over its security [7, 8]. Why because this is one prime platform where it deals mostly with people databases. We have a lot of security breaches in a centralized server. In past there are security compromise incidents that happened with a supervisory control systems as discussed in [9–11]. The major reason to review the security concerns are just because if this is launched in real time exactly the security protocol used for the supervisory system can be implemented with the centralized server too [12, 13]. A small analysis graph shown in the Fig. 3 clarify how bad the security problems are with the current social sites and that should be uprooted in this system once its launched in the future[14].

2.2 Disadvantages of Existing System • There are no specific college related websites where students can post their ideas, experiences, college events etc. • There are many fake profiles of blood donors on many websites. It’s hard-to-find blood donors who are genuine to donate blood [15, 16]. • There are no good enough platforms where students can create rooms or join and discuss things related to study or activities. 2.3 Proposed Model Here we came up with a new idea by designing a new aged fully secured online web platform to log in securely and start chatting, posting, likes, shares, discussing with friends, and many more. We can even post about the events happening in the organization and also can communicate about placements in the college with their friends and alumni which helps the students make the right decision about their future. We introduced a new tool that allows users to discuss their needs and their tasks by entering into a room chat where the room will be created once the user creates and other people can directly join the room and start discussing. On our platform users can share their experiences like what he/she did in interviews or events etc. and also college events, useful stuff on our website. As this is a student-friendly website, many students can search and find different events, experiences, thoughts on our websites which will be helpful for a student in his/her career. Here we also proposed a new feature by adding the user’s willingness for donating their blood or not. While signing up to the platform using his/her details like name, mail, college, and password, he/she able to login to his profile and then using the edit option he/she can able to enter and edit details like blood group, interested to donate blood or not, interests of the user, experience in his/her career, if the user chooses to donate his/her blood then it will automatically update the user’s details in a separate window and the other users who are

in need can contact the person directly without any miscommunication. In this way, our platform can also help behave as an intermediary for the people who require blood. On the blood donor page in our application, all users can find the name, blood group, email, mobile number of the blood donors. It is very difficult to find a blood group of a patient in urgent situations and our platforms help in finding blood donors in one place and this is very useful to society. We can find users who are interested in donating blood. When users logged on our website and can edit their profile such that if a user ticks donate blood then, his/her info gets visible on the blood-donors page as below. We feel difficult to find blood donors at hard times. This helps in saving a life by helping to find blood donors. We also provide small features like liking a post, commenting on a post or editing the post if he/she has privileges. If every student uses this application then we can build a community of students, this will be helpful in finding different opportunities in posts and chatting about topics in Room chat and blood donors (users who are interested in donating blood). 2.4 Objectives Creating a platform for social media helps in sharing posts, college events, placements experiences and ideas. Maintain data privacy and build a good user interface for our platform. To create secured Login for users and profile of users on our platform. To create a platform where users can find blood donors easily, which helps in saving a life. To create a secured group chat application using socket.io.
3 The Architecture of the Project This architecture shows in Fig. 4, when a user visits our website, then he/she must sign up and login to our website, and state management is done through reactjs and restful APIs are passed from frontend to backend using Axios or fetch calls. Then, backend access database using mongoose and creates a new profile for the user while signup and validates credentials while login. This is how the full stack app works as shown above architectural diagram. Using MERN [17] in the project was a foremost advantage for developers as all the code will be written in Javascript language which was very easy to understand if there were errors. Javascript is a programming language where it can be used for both client and server side [18, 19] which makes developers more convenient that they won’t look for other programming tools for both server and client separately because using one language rather than two makes developers very helpful [20, 21]. For developing the project with multiple programming languages we should have knowledge about how to interface them together which makes more complexity. But if we use Javascript, we only need to be expertised/skilled in Javascript and Json. So at the end using Javascript was more convenient and easier for developing good web applications other than using multiple languages. Our website is done using technologies like reactjs, MongoDB, expressjs, NodeJS. On our website, we need to fetch different posts which users uploaded using restful APIs. Reactjs is a library which used to build pages using components that are very flexible

to use and we used mongodb for storing all details of users and posts and express and node js as the server for running our application. 3.1 Methods of Implementation • The implementation of our project is as followed: • Initially to build the project we gathered all the user requirements. • Problem analysis is done to create what type of project that should be built that is unique and different from the other similar platforms that already exist. • Designing of the project is done with user requirements. • Later software and hardware requirements analysis is done to know what we require. Gathering of software and hardware requirements are done. • Developing code to generate a rapid prototype. • Testing of the prototype is done and the bugs are detected. • Debugging of the errors and reconstruction of the project. • Testing repeated for the project to get rid of errors. • With the completion testing phase the project is deployed in the user’s environment [20, 22, 23]. 3.2 Test Cases and Scenarios We will test our application using jest and enzyme for frontend and postman for testing RestfulApis [24–26]. Test cases that were involved in our project are like: • • • •
Users successfully getting signed up on the website. Users successfully logged in on our website with valid credentials. Checking Posts info api from server using postman. Checking editing user’s profile gets successful when the update profile button is clicked.

59
• Checking Like, comment on posts, Blood donors page on the website working properly. These are the test cases which we will check using playwright (e2e) testing and other tools etc. and for checking components of our frontend (reactjs) using jest and enzyme. 3.3 How to Run MERN Application and Use It: These are the steps done to run the MERN stack app: 1. Run both client and server. 2. Open local host with the specified port to access the frontend. Users can sign up to the website and that data gets stored in mongodb. 3. Using users credentials after signup can login to the website and can view other users posts and like them, comment them if the user shows interest in that post [27, 28]. 4. User can follow or unfollow users or organizations, such that, if a user follows a person or the organization, he gets all updates of followed users on a separate following page. This is more flexible and easier to access the following posts. 5. User can create posts by going to create posts on our website. after successfully creating a post, every other user can see his/her post. 6. User can edit his/her profile by mentioning activities, experiences, goals, blood group, and willing to donate blood or not. If the user shows willing to donate blood, then his/her name gets visible on the blood donor’s page on our website. 7. Users can find blood-donors by visiting the blood-donors page on the website. It is a very helpful and social cause that helps in saving one’s life [29]. 8. Users can create or join group chats on the website and start a conversation about the things which they feel they need to discuss (Figs. 5 and 6).
4 Results and Discussion Every user can sign up and Login to our website and be able to access different posts from different users and can be able to follow a particular user or page for more updates and users can able to create a Chat Room or enter into existing Chat Room [30, 31] such that, different users can chat about that particular Chat Room info. Blood donors play a crucial role in saving a life so, it’s difficult to find a blood group in hard times. so, we added a page where users of our application, who are interested in donating blood are visible and if he/she needs blood they can immediately find blood donors according to location, and it’s very helpful in saving a life. In general, we have used the reactjs tool for developing our website which makes our source code into components. Having huge code files also may lead to confusion for both users who access the code and the developers. So having them as small components will help us to a better understanding of the platform and also for integrating the other components/features directly without affecting previous. It even helps in distributing the workload/workspace with others by just distributing the work among others.

5 Conclusion and Future Scope The main idea of the project is to connect students and other people with their colleges or with their friends directly by contacting them in a secured platform and help them in discussing various things that they do together or individually, also users can know different job experiences, events, on Campus drives events on this platform. And also, this platform contains a feature that can be used by the users for donating blood or if they need blood. This can be done by enabling the user to donate blood and on the website it creates a separate window with the full details of the donor provided during their signup by users and the people in need can contact them directly without any third person and any delay.

We can introduce ROOM CHATS where the users can communicate with each other and when they leave the group the chat that they have communicated will be automatically erased and lost, this will help in increasing our security and give the users their privacy. This platform will be unique to the platform that was already present and can be user friendly, users can easily adopt this platform. As our project PALISADE was designed using reactjs components and backend using Nodejs and expressjs and we are using mongodb for database, it will be very helpful and easy to update any new feature to the source as a component and integrate to the main site directly. Like this is a student friendly applications such that, many student are willing to know about different events conducted by different colleges or companies and off campus drives etc. But, because of lack of information they are not able to attend such events. so, our website will be platform where every individual can post their posts which are useful and helpful to others in finding such great opportunities. We can develop a mobile application for the same in future with more advanced features and tools and also can add more features like blood donation.

Comparative Review of Content Based Image Retrieval Using Deep Learning Juhi Janjua(B) and Archana Patankar Department of Computer Engineering, Thadomal Shahani Engineering College, Mumbai, Maharashtra, India [email protected]
Abstract. Review of literature is important for gaining knowledge on specific area before doing any research. In today’s world wide web, pictures are increasing making it difficult to retrieve a relevant image. CBIR is used to search any image from the corpus of images. It excerpts features from the input image and retrieve the images from the dataset which have similar features. Plentiful techniques have been developed for CBIR, some of which have been illustrated in this paper. These results can be improved by finding significant hidden data from images. Deep learning extracts these hidden features and classify the image. Lot of experiments have been conducted on CBIR using deep learning. Comparative analysis of these experiments was performed to outline the superiority of CBIR using deep learning over traditional CBIR methods. An experiment has been conducted to evaluate the efficacy of CNN over traditionally used machine learning algorithms like FNN and decision tree classifier. Keywords: Convolution neural network · Similarity measurement · Deep learning · Features extraction · Content-based image retrieval
1 Introduction “Picture speaks louder than words”, people often prefer pictures over text. Also, the cost of memory has been decreased, making storage of images in a memory cost-effective. Improvements and progress in information technology led to increase in multimedia database. Copious images make difficult to analyze or extract some data from images. Traditionally, images were indexed manually but growing dataset makes it difficult to index the image manually [1]. An alternative approach, content-based image retrieval (CBIR) has been developed. There are various applications of CBIR in different areas such as: medical diagnosis, geographical, military, crime prevention, etc. [2]. There is a scope to improve the efficiency of CBIR in the mentioned field, resulting in the research needed in the field. CBIR is used to search any image from the corpus of images. It analyses data based on the visuals content like shape, color, texture, etc. of an image rather than the text or metadata representing an image [1]. As we can see in Fig. 1, there are two stages in image retrieval process. At first, image features are gathered and kept in the database.

features can be in the form of color, texture, shape, object etc. This feature extraction will be done offline. When the query image will be given, to extract the similar images from the dataset, features will be extracted from it. Some similarity measuring techniques like Euclidean distance, Cosine similarity, etc. will be applied on dataset and query features, to retrieve the similar images [3].
Fig. 1 Process of content based image retrieval
CBIR results can be improved by finding significant hidden data from images. Machine learning algorithms helps to find this information making system intelligent using training datasets. Convolution neural network (CNN) is based on the deep learning approach. It is widely used in image recognition [6]. CNN model is a combination of feature extraction and the classification [4]. CNN models are trained and tested; each input image will be passed in a sequence of convolution layers. Convolution layers consist of three layer which are pooling, fully connected layers and at the end it applies softmax function. Softmax function is used to classify an object with probability value in range of 0 and 1. Higher the probability, better is the chance of classification [1]. Improved network structures of CNNs result in cost effective in terms of memory and computation complexity. Also, it leads to better performance for applications. Further this paper is divided in the sections as follows, Sect. 2 describes the research background, followed by comparison of existing methods in Sect. 3. Section 4 describes the experimentation followed by results and evaluation in Sects. 5 and 6 mentions the inferences in the end.
2 Research Background In this technology era, images are growing rapidly, making precise image retrieval, a challenging task. In image retrieval, semantic gap occurs when low level visual features describe high level concepts, which is a major concern [1–4]. Class based prediction have been proposed and implemented to overcome the semantic gap [3]. Many other techniques include vector of locally aggregated descriptors [4], bag of visual words

model [1, 4], fisher vector descriptors [4], scale invariant feature transform [1, 4], are proposed and evaluated to represent the features of images effectively. Semantic gap mostly occurs due to loss of information while representing image by its local features like color, shape, etc. [3]. This gap can be fulfilled by learning features directly from the images [1–3]. Precision of image retrieval can be increased by finding the hidden information of images. Convolution neural network (CNN), deep learning approach can be used to find the hidden features from the images [1–3]. CNN based models are highly effective in terms of image classification, detection of objects and other problems related to computer vision [1]. Sadeghi-Tehran et al. [2, 10], used a pretrained CNN (residual network (ResNet)). It is used on predefined imageNet dataset. CNN models along with VLAD features have been proved a good fusion to extract the semantic details from the images [3]. CNNs can give accurate classification results if enough data sets along with their labels provided. Overfeat model, pretrained network is used along with CNN for limited datasets, achieving good results in terms of accuracy [4, 12]. Deep learning includes the approach of machine learning algorithms, which by adopting deep architectures used to find out the high-level abstractions in data [1]. Deep Believe Network (DBN) which is a deep learning framework is employed to extract features efficiently for image retrieval. DBN can classify the data with divergence i.e., noise, displacement, smoothness, etc. DBN is reliable as it generates huge data set for learning features [1, 13, 22]. One of the models named Relevance Feedback uses user feedback to overcome the semantic gap. After retrieval of images, feedback is taken from the user whether the retrieved result is useful or not. Based on this, system will get the information regarding semantically similar and dissimilar images. Retrieval results are restored based on the user feedback. This model will stop after delivering the optimal results to the user [2, 3, 14, 15]. CNN can learn image representation and binary codes simultaneously if data is labeled [4]. Lin et al. [16] method generates the binary codes, which are then used for searching by calculating hamming distance. For searching the images in a dataset, hashing based search takes lesser computational time than linear search. Texture classification is one of the challenging tasks in image retrieval. Principal Component Analysis, PCANet has set a modest standard for the texture classification and object recognition [17]. PCANet has three basic modules, binary hashing, cascaded PCA and blockwise histograms. PCANet is used to learn the filters from the data. Binary hashing is used for indexing and histograms are used for pooling. Tzelepi and Tefas [8] proposed three different retraining models i.e., retraining with relevance info, fully unsupervised retraining and Relevance feedback based retraining. These models have outperformed other CNN based models.
3 Comparison of Existing Methods There are many issues which is been faced during retrieval of images based on its content. Some of the issues are semantic gap, geometrical transformations, different illumination condition, texture representation as seen in Fig. 2.

Fig. 2 Different issues in CBIR
Many papers have been reviewed on content-based image retrieval (traditional methods) and content-based image retrieval using deep learning. Summary has been given of the traditional CBIR methods in the Table 1. CBIR for biomedical images using hybrid approach of relevance feedback by taking users feedback have been proposed [14]. In this model, it compares query image features with features index of image which are stored in dataset. It uses graph ranking techniques to find similar images. These images will be judged by users whether they are relevant or not to the user query to tackle semantic gap. This model is most beneficial for repeated users and for small number of feedbacks. This system was tested on 100 images dataset. It gives accuracy of 60–75% using Navigation Pattern based Relevance Feedback (NPRF). We face many issues like multiple illuminates while classifying an image. A descriptor has been proposed which combines the local binary pattern (LBP) and local colour contrast (LCC) to handle multiple illuminates [18]. LBP is used to extract the texture features and it is robust to variations in illumination changes of images. Whereas LCC is used to retain the colour information and discard that part which is affected by illumination changes. Combining LBP & LCC gives 77.1% accuracy of image classification. Geometrical image transformation is yet another issue which is been faced during image retrieval. Srivastava [19] examined two techniques i.e., Speeded Up Robust Feature (SURF) and Scale Invariant Feature Transform (SIFT) for such image transformations [19]. It has been observed that for all the cases SIFT gives better results than SURF. Although both these techniques give better retrieval only on affine transformations on images. For texture representation, local descriptor named—Local Derivative Radial Pattern was proposed [20]. This proposed method was compared with methods which are predefined such as local vector pattern, local binary pattern, local ternary pattern, local tetra pattern and local derivative pattern. This method shows better accuracy by at least 3.82 and 5.17% when it tested on Brodatz and VisTex datasets, respectively. Though it outperforms many prior methods, its accuracy is less than 80% when number of images retrieved are 30. Semantic gap in CBIR is a distinction between image low-level features and humanbeing high-level perception. Basically, it is the gap between the request of image retrieval and its actual features. Color feature is considered an important feature for retrieval of

images. But it is not a reliable feature due to different illumination condition of an image. Texture describes the feel of a surface. Texture of an image refers to the visual of an image. It is defined by the illumination of the pixels. The analysis of texture encompasses many issues like classification, segmentation, etc. Geometrical transformation is yet another major issue in retrieval of similar images. As we can see in Fig. 2, same building image is captured with variations like different angle. These above-mentioned challenges can be overcome by finding significant hidden information from images. Deep learning algorithms can be used to find this hidden data from images. Convolution neural network, a deep learning approach is a neural network

vastly used for image processing like classification, segmentation, etc. The crux of CNN is to focus on the portion of an image rather than processing an entire image for feature extraction. Many techniques of CBIR using deep learning on different datasets have been implemented. It gives better accuracy results than traditional CBIR methods. Summary of these techniques have been shown in Table 2. Table 2 Comparison of deep learning based CBIR techniques Paper

Results of CBIR have been increased by 2–3% by combining relevance feedback of users [15]. Retrieval results keeps on changing based on the user feedback. Once the results meet the user’s expectations, this model stop running and return the result to the user. In this, deep learning with five convolution layers is used. For similarity

measurement, Euclidean and Cosine similarity techniques are used. This experiment has been carried out on caltech257 dataset consisting of 30,607 images of object. Sun et al. [11] used framework consist of feature extraction, indexing and querying. In feature extraction, object is detected first by using BING. Features are extracted using the fusion of CNN & VLAD. CNN specialize in describing general semantics whereas VLAD in describing local details of images. Fusion of CNN & VLAD gives accuracy of 83.7% on Holidays dataset consisting of 1491 holiday images from 500 classes. This fusion gives better accuracy than standalone CNN & VLAD features. Inverted indexing structure is used in database to avoid exhaustive search. In another recent study [10], pre-trained CNN [residual network (ResNet)] is used on predefined imageNet dataset. Novel nested hierarchical database indexing is used for querying from the database, which is faster way to process the query, using k-means clustering. For similarity matching, recursive calculation is done based on local density estimation. This framework is tested on MalayaKew (MK) Leaf-Dataset, having 44 classes with 52 images in each. It gives accuracy of 88.1%. And it gives 90.5% accuracy using University of California Merced (UCM) Dataset, having 21 classes having 100 images in each. CNN when trained with large dataset with labelled data gives good accuracy than the limited labelled data. Marmanis et al. [12] proposed a two-stage framework which gives better accuracy with limited labelled data. In its first stage it is using pretrained Overfeat model, higher version of AlexNet [21] model which is trained using 1.2 million images. The second component is the trainable classification architecture which accepts 2D feature as an input. This framework gives 92.4% accuracy when tested on UCML dataset, consisting of 2100 images of aerial images of US cities. Sometimes the images of dataset are incredibly challenging because of its nonlinearity. These images should be pre-processed to increase the efficiency of the system by speeding up the time of training. Random rotation and horizontal flips on images help CNN to be insensitive of the image orientation. ZCA (Zero Component Analysis) [29] is used, it decreases the redundancy in the pixels of image and emphasizes on its structure and features. This framework gives 92.86% accuracy when used on Food-11 which consists of 16,643 images having 11 major food classifications [9]. Tzelepi and Tefas [8] proposed three models: (i) Retraining with relevance information, this model is used if the training dataset labels are available, (ii) Fully unsupervised retraining, this model is used when only dataset is available, (iii) Relevance feedback based retraining, this model is used when feedback of user’s is available. All three models are tested with two datasets: UKBench2 dataset comprised of 10,200 object images classified into 2550 classes (with each class containing 4 images) and Paris 6 K dataset containing 6392 images. Cosine similarity and Eucledian distance is used for similarity measurement. The accuracy of CBIR is dependent on the feature’s representation of an image. Deep Belief Network (DBN) method [23] is applied to retrieve image features and classify the data with divergence i.e., noise, displacement, smoothness, etc. In Saritha et al. [13] method, multi-feature retrieval technique is introduced. This technique combines features of edge directions, color histogram, texture features, edge histogram, etc. These

features are obtained and stored as a small sign of an image. For similarity measurement, these signatures are compared. This framework is tested on SUN dataset. It gives accuracy of 98.6% for small dataset (images < 1000) and 96% for large dataset (images > 10,000). CBIR gives best results when class based prediction with CNN is used. For the proposed content based medical image retrieval (CBMIR) systems, it has been tested with a dataset [7]. This dataset consist of 24 classes with 300 images in each class, is prepared from the publicly available medical dataset. CBMIR gives 99.77% classification accuracy, mean average precision of 69% for image extraction, 53% when class predictions is not used. Lin et al. [16] proposed a deep learning architecture which retrieve images by calculating binary hash codes. This framework consists of three components: (i) CNN is pretrained with supervised learning using imageNet dataset, (ii) hidden layer is added to learn the hash codes of the images, (iii) to retrieve similar images using hamming distance between binary codes. This framework is tested with three different datasets, namely MNIST dataset, CIFAR-10 dataset and Yahoo-1 M dataset. The retrieval accuracy with all three datasets is shown in Table 2. PCANet proposed by Tsung-Han Chan et. al., [17] is based on principal component analysis, blockwise histograms and binary hashing. It proved as a simple but provides extremely competitive standard for object recognition and texture classification. PCANet is tested on various datasets namely LFW dataset, Extended Yale B dataset, FERET dataset, and AR dataset giving remarkable accuracy as shown in Table 2.
4 Experimentation This paper summarized the techniques of traditional CBIR and CBIR using deep learning methods. Also, experiment has been conducted on Fashion MNIST dataset [24] and compared the results of decision tree classifier, Feed-forward Neural Network (FNN) and Convolutional Neural Network (CNN) model. 4.1 Decision Tree Decision tree classifier is a supervised machine learning algorithm which is used to classify the data [25]. It uses divide and conquer strategy. Each internal node of this tree represents attribute test, every branch of a tree represents result of test and leaf node indicates the class label [26, 27]. In CBIR, attributes which are used in decision tree is the visual feature of the images [27]. In this experiment, for optimizing decision tree classifier, it was trained with maximum depth of tree as 50 and random state as 42. 4.2 Feed Forward Neural Network Feed forward neural network, an artificial neural network is used for classification. In this the data moves in forward direction. All the nodes in the layers are fully connected with one another [28]. This paper indicates the results of feed forward neural network, which is established on the sequential model. In this network, dense layer has been added

along with the ReLU activation function to introduce non-linearity. The output layer is a softmax layer as the Fashion MNIST dataset is a multiclass dataset. The optimizer which is used in this experiment is Adam optimizer. 4.3 Convolutional Neural Network Convolutional neural network is a deep learning approach, majorly used for image classification [29]. The pre-processing required is very lesser than the other classification algorithms. These networks do learn filters itself. One of the advantages of using CNN over other neural network, there is no need to flatten the image. CNN can work with 2D images, which results in a great learning of image properties. In this experiment, convolution layer has been added along with the ReLU activation function and softmax function at output layer.
5 Results and Evaluation To test the proposed experiment, Fashion MNIST dataset is used. This dataset comprises of Zalando’s article images which consist of 60,000 training images and 10,000 testing images with 10 classes labels [24]. The evaluation measure which is used to compare the above three mentioned algorithms is accuracy. This measure is defined as the ratio of no. of images correctly categorized to the total number of images as shown in Eq. 1 [30]. Accuracy =
no. of images classified correctly total number of images

Table 3 shows the accuracy measurement of decision tree, FNN & CNN algorithms on scale of 0–1. Using only one layer of convolution layer in CNN, it outperforms decision tree and FNN models. Accuracy of CNN can be increased further by adding more such convolution layers.
6 Conclusion CBIR is used to extract the image from the corpus of images with the help of its features. In this paper, we have given summary of different research studies on content-based image retrieval (CBIR). Many issues of CBIR have been discussed. For each issue, one research study has been discussed. This CBIR retrieval accuracy can be improved by finding significant hidden data from images.

Abstract. Traffic congestion is an extremely common phenomenal issue, it occurs in many cities around the world, especially in those cities with high car ownership. Traffic congestion not only causes air pollution and fuel wastage, but it also leads to an increased commuting time and reduces the work time availability. Due to these reasons, traffic congestion needs to be controlled and reduced. The traffic light is the most widely adopted method to control traffic, however, most traffic lights in use are designed based on the predefined interval, which cannot cope with traffic volume change very well. Therefore, Internet of Things (IoT) based traffic lights or adaptive traffic lights are developed in the recent years as a complement of the traditional traffic lights. The adaptive traffic light can be built based on monitoring current traffic situation or using Vehicle-to-Vehicle and Vehicle-to-Infrastructure communication. In this paper, a new design of adaptive traffic light is proposed, this traffic light system is based on fuzzy logic and it introduces volunteer IoT agent mechanism, which introduces more accurate results.
1 Introduction Traffic congestion refers to the phenomenon of a road traffic bottleneck that produced by heavy car’s traffic that heading to congested intersections with a slow speed. This case is usually occurring during rush hours and holidays. This situation often occurs in major metropolitan areas around the world, areas with high automobile usage, and highways connecting two cities. Frequent traffic congestion leads to an increased commuting time and it reduces the time available for work, resulting in economic losses due to workers delay getting their working places on time, delay of delivering goods on time and so many other factors. It also causes drivers to feel irritated and impatient, which increases their stress and further damages their health. To a certain extent, traffic congestion is also a waste of fuel and pollution: Engines keep running during traffic congestions, which consumes extra fuel, and at the time of congestion, drivers always accelerate and brake back and forth, which further increases fuel consumption. Traffic congestion therefore not only wastes energy, but also causes air pollution. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2022 V. E. Balas et al.

Therefore, in this paper, a design of adaptive traffic light is proposed, this traffic light system is based on fuzzy logic and it introduces volunteer IoT agent mechanism to make sure the system gives a more accurate result.
2 Related Work There are many studies, which have examined different methods on traffic management. The authors of [1] proposed a traffic con-gestion detection system in their paper, their system consists of I2I (infrastructure-to-infrastructure) communication method, V2I (vehicle-to-infrastructure) communication method, V2V (vehicle-to-vehicle) communication method, and big data cluster. The system uses abovementioned three communication method to collect all the vehicular information such as vehicle’s latitude, vehicle’s longitude, and vehicle’s speed. Then data is encapsulated in DATA packets by using the LORA-CBF algorithm and transmitted to the big data cluster. In big data cluster, received data is interpreted and further analyzed by using algorithm based on Binary Traffic Output (BTO) algorithm proposed by [2] to identify potential traffic events such as traffic congestion and traffic accident. Similar work has been done in [3], this proposed system employs V2I communication technology based on WAVE IEEE 802.11p standard and uses fuzzy logic to coordinate vehicles on the road. Fuzzy control system considers each vehicle’s comfortable and safe distance and speed adjustment to prevent collisions in advance and improve traffic flow. This traffic management system can analyze received information and sending warning or recommendation commands to the vehicles. In the article [4], authors built an IoT based traffic junction model, with several ultrasonic sensors placed on sides of road to count the number of cars and connect sensors to Arduino microcontroller, then data is transmitted to Raspberry Pi3 microcontroller through Wi-Fi module, where analysis been carried out. The traffic was categorized as heavy and normal traffic, as well as based on the traffic density, traffic signal time has been changed accordingly. Azura che soh, Lai Guan Rhung and Haslina Md. Sarkan have conducted a research on adaptive traffic light system by using Matlab simulation, in their research paper [5] they developed a fuzzy traffic controller based on vehicles queue length and waiting time at cur-rent green phase. They compared fuzzy traffic controller (FTC) with vehicle-actuated controller (VAC) and found that the fuzzy controller distinctly reduces average waiting time, average queue length and delay time. In another research done by authors of [6], it divides the status of inter-sections into four categories. Then based on the evaluation of the status, it adopts a fuzzy reasoning method to evaluate the traffic operation status of intersections and formulate corresponding traffic management method for traffic congestion.
3 Proposed Approach Since traffic congestion has many negative influences on people’s daily life, the objective of this paper is to build a traffic light control system based on fuzzy logic. The system should be able to determine the duration of traffic light’s green time based on given inputs, which are traffic saturation, queue length and traffic status from volunteer IoT

agent. The system will monitor traffic condition during current traffic light cycle (one traffic light cycle contains three different phases, green light phase, yellow light phase and red-light phase), then the system will adjust the duration of green light phase in the next traffic light cycle. Eventually, this system can help to improve traffic efficiency in a traffic junction and manage traffic more effectively by adjusting traffic light’s green time. Figure 1 shows how system’s architecture at a traffic junction.
Fig. 1 Working scenario of the system
In Fig. 1, four sensors are deployed on the side of the road. Vehicles count sensor is placed right next to the traffic light. During the green light phase, every time a car passes through the intersection the movement can be captured by this sensor. The total vehicle count is the actual traffic volume in the intersection, after getting the total vehicle count, this value is then used to calculate traffic saturation, which is explained in Sect. 3.1.2. Pre-threshold, threshold and post-threshold sensors are used to detect vehicle queue length during the red-light phase. If queue length ≤ 0 M, the pre-threshold sensor will be triggered. If (40 M < queue length < 60 M), the threshold sensor will be triggered. While, if the queue length ≥ 60M, the post threshold sensor will be triggered. In Fig. 1, there are two volunteer IoT based agents at the intersection, volunteer agents can observe and evaluate traffic situation and send traffic situation value (e.g. minor congestion, severe congestion) to the control system, details of volunteer agent are discussed in Sect. 3.1.4. In the real life, there can be multiple volunteer IoT agents in one intersection observe and send traffic situation data at the same time. However, this paper will assume only one volunteer IoT agent is allowed. Another assumption in the paper is that there are no turns involved, only straight through traffic, vehicles can only move from East to West or from North to South as shown in Fig. 1. Since the proposed method in this paper is built by using simulation, all the inputs will be retrieved from a created input file, input file contains pre-defined possible values for inputs variables. Input files for each parameter are discussed in Sect. 3.1. 3.1 Design of Fuzzy Inference System The fuzzy inference system (FIS) consists of fuzzification, knowledge base (membership functions and fuzzy rules) and defuzzification [7]. FIS takes crisp inputs and converts

them into fuzzy inputs by using membership functions, then it combines fuzzy inputs together to come up with a fuzzy output based on fuzzy rules and output membership functions. Figure 2 [7] illustrates the workflow of fuzzy inference system in this paper.
Fig. 2 Computation of output Green Time
3.1.1 Fuzzification of Inputs and Outputs The fuzzy inference system takes three inputs, which are discussed in detail by the following sub-sections: 3.1.2 Traffic Saturation This input metric indicating the degree of saturation of an intersection under traffic signal control is a measure of how much demand it is experiencing compared to its total capacity. Road saturation refers to the ratio of actual traffic volume and capacity of the road, it can be represented byx, and calculated by using equation x = Qq , where q is actual traffic volume and Q is total capacity. x can be any value between 0 and 1. If x is greater than 0.9, the traffic condition at the intersection deteriorated sharply, and traffic congestion is very likely to occur [8]. In this paper, the total capacity of the intersection is assumed to be 100 (Q = 100), which means during one green light phase, the maximum number of vehicles to pass the intersection is 100. Membership function of traffic saturation is shown in Fig. 3. Y-axis indicates the degree of membership; X-axis indicates traffic saturation during the current green light phase. Input file for traffic saturation is named Green Phase Car Count Input File, this file contains all the integer numbers from 0 to 100, in each green light phase, system will

79
Fig. 3 Membership function for traffic saturation
randomly retrieve one number from the file as the actual traffic volume (e.g. q = 50) during that green light phase, then q is substituted into equation x = Qq to calculate road saturation x. 3.1.3 Queue Length The queue length input metric refers to the length of space occupied by the stopped vehicles; it can reflect the traffic flow at the intersection. It is of great significance for evaluating the operation status of the intersection, measuring the severity of traffic congestion, and evaluating the existing signal timing plan. In general, the more severe the congestion, the longer the length of the queue. The membership function of traffic saturation is shown in Fig. 4. Y-axis indicates the degree of membership; X-axis indicates queue length which is measured in meters.
Fig. 4 Membership function for queue length
As mentioned above, pre-threshold, threshold and post-threshold sensors are used to detect vehicle queue length. If the pre-threshold value is triggered, it is considered as normal traffic condition, if the threshold is triggered, it is considered as minor congestion, if the post-threshold value is triggered, it is considered as severe congestion. Input file for queue length is named Queue Length Input File, as indicated in Fig. 4, the minimum queue length is 0 m and maximum queue length is 100 m. Therefore, this file contains all the integer numbers from 0 to 100, during each red-light phase, the system will randomly retrieve one number from the file as queue length during that red light phase.

3.1.4 Traffic Status from Volunteer IoT Agent Traffic information will be also gathered from volunteer agents, which could be any person from nearby traffic junction, they can observe and provide traffic situation information to the control system by mobile application. With the help of volunteer agents, the system takes account of nearby traffic junctions. For example, in case both current and next traffic junctions are having severe congestion, if the control system gives green light to current traffic junction, vehicles from current traffic junction will flood into next traffic junction and cause even worse traffic congestion. One solution can be extending the green time in next junction to clear out vehicles, while current traffic junction can extend red time to hold vehicles, after the vehicles in the next junction have been cleared out, the current junction can open green light to let vehicles to pass. However, in this paper we will assume all volunteer agents come from current junction, which means the system will only consider traffic situation at the current intersection. Volunteer agent uses a scale of 1 to 5 as an indication of the traffic situation, 1 stands for no congestion while 5 stands for severe congestion. Meanwhile, a trust level is assigned to each volunteer agent. Trust levels have values of high, medium, and low trust level, each trust level has its own weight, high = 20, medium = 15 and low = 10. Calculation of a volunteer agent’s value involves following steps: Step1: volunteer agent provides a number (e.g. 4) to indicate current traffic situation. Step2: system identifies volunteer agent’s trust level. (e.g. medium). Step3: multiply number provided in step1 (in this case = 4) with the corresponding weight associated with trust level (in this case = 15), 4*15 = 60. The result of step 3 (which is 60 in this case), is then used to evaluate traffic situation by using membership function as shown in Fig. 5.
Fig. 5 Membership function for traffic status from volunteer agent
Traffic status from volunteer agent has two input files, one file is called Volunteer Agent Value Input File, which contains integer numbers from 1 to 5, these numbers are used by volunteer agent as a scale to indicate traffic situation. Another file is called Volunteer Agent Trust Level Input File, since there are three trust levels, high, medium, and low. Thus, this file contains 3 numbers 20, 15 and 10, each number represent high trust level, medium trust level and low trust level, respectively. During each green light phase, the system will randomly choose one number from each file to calculate volunteer agent’s value.
Fuzzy-Logic Approach for Traffic Light Control Based on IoT Technology

The output of the system is a variable called GreenTime, which indicates how long the green traffic light will glow on next traffic light cycle. Membership function for output is shown in Fig. 6.
Fig. 6 Membership function for green time
In the above figure, X-axis indicates the duration of the next green light phase, which is measured in seconds, maximum duration is 120 s. 3.2 Fuzzy Inference Engine This section explains how fuzzy rules are derived. Fuzzy inference engine consists of a group of rules. There are 3 input parameters in this paper, both traffic saturation and traffic status from volunteer agent have 4 membership functions, so they both have 4 possible values: normal, minor congestion, medium congestion, and severe congestion. The other input, queue length, has 3 membership functions, so it has 3 possible values: normal, minor congestion and severe congestion. Therefore, there are 4*4*3 = 48 rules in total. First, since all the inputs have the same weight, and order of inputs does not matter, thus, 48 rules can be classified into 19 different patterns, each pattern is assigned with an output value as shown in Table 1. This table is then used to identify output for each rule.
4 Implementation and Initial Results Our implemented adaptive traffic light system consists of a main class, a fuzzy inference system, an interface file, a get input class and 4 input files. Main class controls traffic light cycles and retrieves input data from input files by using data retrieving method in getInput class, and feed data, which are traffic saturation, queue length and traffic status from volunteer agent, into fuzzy inference system, fuzzy inference system will return an output which is green time, then main class will update user interface according to green time. Figure 7 shows internal design of the whole system. A user interface has also been developed for visualizing purpose. With the help of simulation, people can better understand how the system works and see what is happening right now.

Figure 8 is the starting screen of the paper, it is the main entrance of the program, starting screen shows the method’s title and some explanations about the proposed technique and its parameter settings. When the Start button is clicked, the callback function of the Start button will be invoked, new simulation screen will be showing, and the system will start running. Figure 9 is the simulation screen before the program starts running, there are two traffic direction, North–South traffic, and East–West traffic. Each traffic direction has its own traffic light, which are North–South Traffic Light and East–West Traffic Light. Traffic Saturation NS/EW, Queue Length NS/EW, and Volunteer Agent Value NS/EW text boxes are used to display values of input data. Duration of the current traffic light is displayed on the top right. Figure 10 shows what will the simulation screen look like after the program is running and the pre-threshold sensor is triggered. A green arrow is showing to indicate the current green light direction, which is East–West traffic, so the duration of East–West green light is displayed on the top right, this duration is calculated based on Traffic Saturation EW, Queue Length EW, and Volunteer Agent Value EW, however, since currently East–West direction is green light, thus, Queue Length EW is set to zero.

Abstract. Due to increasing databases of all kinds, clustering has become one of the most essential tasks to classify the data. Clustering means to group or divide the data points based on their similarity to each other. Clustering can be stated as an unsupervised data mining technique that describes the nature of datasets. The main objective of data clustering is to obtain groups of similar entities. There are various methods of clustering such as hierarchical, partition-based, method-based, grid-based, and model-based. This paper provides a detailed study about clustering, its working processes. Along with basic information, detailed information about validity measures required to evaluate algorithms is discussed. This paper reviews clustering algorithms like K-Means, Agglomerative, and DBSCAN. A tabular comparison of algorithms is represented to acquire in-depth knowledge. The results obtained after experimenting with algorithms are also been discussed at the end. Keywords: Clustering · Data mining · KDD · K-Means clustering · DBSCAN · Agglomerative · Clusters
1 Introduction With the advancement of technology, and systems getting complex, it’s the databases that are expanding at an exponential rate. Often while developing systems, there comes need to understand the data well and categorize it individually. Acknowledging the significance to clear the clutters of data, data mining is a practice widely adopted by researchers and developers. Data mining is the process of forming clusters of similar data and discovering patterns and trends which go beyond the simpler analysis [1]. With the help of data mining, the relation between large datasets is investigated and it helps to predict the most probable outcomes. Data mining is also used to detect anomalies in the dataset. The raw data gets converted into useful information which is required for further analysis. The data mining algorithm first searches for patterns in the data and these patterns help developers across the globe to learn more about clusters, thereby developing market strategies and product manifestations. Also, Data Mining is the analytical step of KDD i.e., Knowledge Discovery in Databases. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2022 V. E. Balas et al.

Data Clustering Algorithms: Experimentation and Comparison
87
Despite the similarities between data mining and statistical data analysis, most of the methods used in Data Mining are originated in fields other than statistics. The working of the algorithm depends on effective data collection, data warehousing, and computer preprocessing. 1.1 Working of Data Mining Algorithm The algorithm first explores the given dataset and then starts analyzing it into large blocks of information to acquire meaningful patterns present in the data. The process of Data Mining can be divided into 5 steps as follows: Step 1: To collect the data, organize it, and load it into the warehouse. Step 2: After organizing, load the data into house serves or the cloud server. Step 3: Various professionals of the company such as analysts, members of management teams, and IT teams trying out ways to organize and store the data processed. Step 4: Sorting the data based on various factors such as target variable, user results, etc. by the software application. Data Mining is divided into 3 categories. • Classification • Clustering • Association Mining.
2 What is Clustering? Clustering is the data mining task that is used to determine the value of a number of clusters and data objects which is given as input to the algorithm [2]. The main aim of clustering is to segregate groups with similar features and assign them to one cluster. Clustering is one of the most popular techniques in data science. The data points are assigned into some clusters as per their similarity with other neighbor points. The similarity between sample points is measured by features and a metric called the similarity measure. But as the number of features increases, it becomes complex to find their similarity and group them accordingly. As shown in the above Fig. 1 [3], is the process of how clusters are formed and how subsequently interpretation of data takes place through the knowledge obtained. Firstly, the raw, untreated data undergoes the process of feature selection. Feature selection is the process by which those features are selected that will contribute and have the most resemblance to predict the possible outcome. Having irrelevant features in data can decrease the accuracy of the result. Also, the feature selection method largely impacts the performance of the model. By the use of feature selection, overfitting is reduced, the accuracy of the model increases and also it takes less time for training of the model. The next step after feature selection is applying the initial clustering algorithm. As the task of clustering is subjective [4], the paths to achieve the goal are plenty. Hence, after running the algorithm on the data, initial tentative clusters are formed based on
88

Fig. 1 Clustering process
the similarity indexes. The results obtained after forming initial clusters are validated to form the final clusters of the data. Once, the final clusters are formed, the data is now ready for developers to interpret and perform operations on the processed data and gain outcomes.
3 Clustering Algorithms 3.1 Partition Based Method The partitioning method classifies a group of data based on characteristics and similarities present in the data. The number of clusters needs to be mentioned prior to generating clusters [5]. In the partitioning method, when database D contains N multiple objects, then the partitioning method constructs K partitions of data representing clusters and particular regions. 3.2 Hierarchical-Based Method In the hierarchical based method, the data objects are arranged in a hierarchical manner using the proximity measures. In Hierarchical clustering, every data point is treated as a separate cluster [4]. Once clusters are been formed, the following steps are been performed again and again: Step 1: Identifying 2 clusters that are closest to each other. Step 2: Merging 2 maximum comparable clusters. 3.3 Density-Based Method: Density is defined as the number of objects in the given region. This method uses the concept of density connected objects. These models search the data space over the given dense regions [6].
Data Clustering Algorithms: Experimentation and Comparison
89
Density-based algorithms play a vital role to find non-linear shape structures depending on their density [4]. The cluster formed by similar data points starts growing in the same direction as that of density. This method also handles the outliers present in the database. The main concept revolves around forming clusters of data points with nearest neighbors. 3.4 Grid-Based Method In this method, space is been divided into multi resolution grids for quick processing of data. The great advantage of the grid-based method is the significant reduction of computational complexity [7]. The performance of clusters depends upon the size of this grid, as the grid size is smaller than the original datasets. The only disadvantage of this method is that a single uniform grid is not sufficient for high-quality clusters having irregular data. 3.5 Model-Based Method In Model-based clustering algorithms, we can use one of the models to form clusters from the given dataset. The basic principle is to optimize between the mathematical models and datasets. This method uses probability distribution to generate the clusters [8].
4 Algorithms 4.1 K-Means Algorithm The K-Means algorithm is a centroid based technique that takes an input parameter K from the user and predicts the most similar data group and gives in K clusters. There are 2 parts of the group: intracluster and intercluster. Intracluster means the group of data objects inside a particular group or cluster having high similarity whereas intercluster includes the group of data points with low similarity. As shown in above diagram (Fig. 2), the K-Means algorithm is illustrated by the
Fig. 2 K-means algorithm illustration
following process. Input data consists of Dataset ‘D’ having collection of different data points and value of number of clusters ‘K’. Further, K-Means algorithm is implemented onto the input data gathered. Output of K-Means is in the form of clusters according to the value of k.
90
A. Khandare and R. Pawar
Algorithm:
1. Select k objects as inial centroids. 2. Repeat ll no changes are observed. 3. Find distance between data objects and centroids. 4. Form clusters by assigning data objects to the closest centroids. 5. Update centroids. K-Means algorithm starts by determining the accurate value of ‘k’. In the first step, centroid is calculated of given data points. The distance between centroid and object data points is calculated later. Based on the minimum distances formed, clusters are formed. The data points that have least distances, are grouped into single cluster. The algorithm further checks whether the object is present or not. If the answer is yes, then again re-running all the above-mentioned procedure, updates centroid, distance values and clusters. This loop gets terminated when there is no more single object present as a single entity in the space and all of them are classified into some or the other clusters. All the data, is represented by means of flowchart in Fig. 3. 4.2 Agglomerative Clustering Algorithm An agglomerative Algorithm is a bottom-up approach that seeks to build a hierarchy of clusters. In this method, pairs of clusters are merged as one moves up the hierarchy [9]. The results are usually in the form of the dendrogram. In Clustering, Agglomerative is one of most widely used algorithms. The basic idea behind Agglomerative is “Merge & Split” in greedy manner. As shown in Flowchart of Agglomerative Algorithm, Fig. 3, Initially the inputs are considered i.e., all the data points are loaded. In this algorithm, each and every single data point is considered as distinct cluster. Then a pair of data points in clusters are considered with minimum value of dissimilarity. This process keeps on repeating until one big Cluster containing all data points is formed.

Figure 4 is the output of the Agglomerative Clustering Algorithm. After the algorithm is implemented onto the dataset, a dendrogram as shown in figure is produced. The above dendrogram represents clusters formed based on the data of Height of some people in different countries. Initially, in the bottom, all the countries are considered as single entity i.e., cluster. Then according to similarity and dissimilarity between each other, clusters keep forming, until one big cluster of all countries is formed.
5 About the Dataset For implementation of clustering algorithms, two datasets were considered, synthetic and real. Dataset is collection of information usually in the form of columns. The first dataset was synthetic one and was created using ‘make_blob’ feature from Sklearn library. Whereas the second dataset was real dataset, that contained information about university. 5.1 First Dataset This dataset was created using ‘make_blob’ feature of Sklearn library. This dataset consisted of 200 samples having 4 cluster centers, with an average cluster standard deviation as 1.8. The data was an array of coordinates randomly stated in state space with shape (200,2).

Fig. 4 Sample Dendrogram
As stated, and visualized in the above Fig. 5, the dataset is formed using 4 cluster centers, which makes it prone to form 4 distinct groups.
Fig. 5 Synthetic dataset
5.2 Second Dataset The second dataset used for analysis was ‘The University Dataset’. The main aim was to classify the dataset into two groups namely ‘Private’ or ‘Public’. This dataset consists of 18 variables and 777 observations. As it is an unsupervised learning algorithm, the dataset is without labels. Since, dataset is based on University, variables could be the number of students enrolled in university, their Application Count, Faculty Count, Types of Streams, Courses Enrollment, Students count in Undergraduate or Post Graduate streams, information about Fee Structure, Study material and Alumni Contacts and many more.

Although the variables stated are just mere obvious predictions and they don’t even affect the working of our algorithm. 5.2.1 Visualizations Figure 5 is heatmap of the dataset. Heatmap is a way to show some sort of relation between the variables/columns of the dataset. The above heatmap represents correlation between variables, with an index ranging from −0.8 to 1.0. With index of −0.8 exhibits very little correlation and index 1.0 means perfectly correlated to each other.
Fig. 6 Heatmap of variables of dataset
Initial Inferences from dataset: • • • •
No Null Values are present in the data. Skewness in the data ranges from −0.8 to 3.7. Out of the 18 variables, 6 variables had balanced data. Out of 12 variables left, 20% were left skewed and rest 80% were right skewed.
5.2.2 Data Imbalance Data Imbalance refers to a state wherein data points are not equally classified into classes. It means some classes have fewer data points than other classes. The classes that have fewer data points are called as minority classes whereas the ones with more data points
94
A. Khandare and R. Pawar
are termed as majority classes. Training any model onto imbalanced data results in poor predictive performance of the algorithm, especially for minority class. Often the data gets imbalanced due to Measurement Errors or Biased Sampling of data. Some of the imbalanced data is shown below. From the above Fig. 7, it can be infered that the data is unevenly distributed amongst the classes. This means that most of the data either tends towards Maximum value or minimum value.
Fig. 7 Data imbalance visualization
The imbalance present in data can be corrected by the use of sampling methods or correcting the error raised during measurement. This is majorly because the training dataset is not the representation of the problems.

95
5.2.3 Outliers Outliers represent the data points that are placed at an abnormal distance as compared to other data points in the dataset. The presence of outlier may be because of the variability in measurement of data or some experimental error. Outliers can cause major statistical errors. Outliers can also arise due to changes in behavior of system or fraudulent, also human or experimental error. Some outliers were detected in the dataset as shown below: Figure 7 represents outliers in all the columns present in the data. On an average, 4.41% is the average outlier present amongst 17 features. With highest outlier noted on Column C and lowest in Column F with 9.39% and 0% respectively. Column.
Fig. 8 Outliers present in the dataset
Outliers in the dataset can increase variability and decrease the statistical power. And hence it is necessary to treat these outliers. However, if the outliers don’t much affect the results, then there is o need to delete the outliers. But, in our case, results are altered. 5.2.4 Outliers Truncation The outliers in this dataset, was removed by using Interquartile Range Method. Interquartile Range Method, also known as IQR, is calculated as the difference between the 75th and 25th percentiles of data. It defines the box in Box and Whisker plot. After the truncation process using IQR Method, all the outliers were successfully removed. According to Fig. 9, all the columns have 0% of outliers.
6 Validity Measures Along with outcomes obtained by executing algorithms, there is also a need to measure the performance and its validity. The validity measures [10] are usually used as fitness functions that help to evolve the quality of clusters formed after every iteration. All the
96
A. Khandare and R. Pawar
Fig. 9 Outliers after truncation process
measures are dependent on the data. All the validity measures might not be time-efficient but they may affect the quality of the cluster. Cluster validation and evaluation techniques supports as procedure to evaluate the goodness of the clusters formed. By validating clusters finding patterns in random data can be avoided. The main aim is to evaluate the quality of clusters formed. Evaluation and Validation parameters include. • Precision: Precision refers to the what percentage of obtained results are relevant. It can be defined as the ratio of correctly predicted positive observations to total predicted positive observations. • Recall: Recall is the percentage of the total relevant results that are been correctly classified by the algorithm. It is the ratio of correctly predicted positive observations to all the observations in actual class. • F1 Score: F1 score can be determined as weighted average of Precision and Recall. And hence it takes into account false positives and false negatives. • Accuracy: Accuracy stands as the most intuitive parameter to measure and evaluate the performance of the algorithm. It is the ratio of correctly predicted observations to the total observations. • Calinski Harabasz Score: It is also known as the Variance Ratio Criterion. Calinski Harabasz Score is the sum of between-clusters dispersion and inter cluster dispersion. Higher the score, better the performance. • Silhouette Score: Silhouette value determines how close a particular object is to its own cluster and compared to other clusters present in the data. The range of score is from -1 to 1, where a high value indicates that the object is well matched to cluster and poorly matched to neighboring other clusters present.

7 Result And Discussion 7.1 K-Means Algorithm This clustering algorithm is based on a partitioning approach. The algorithm is applied to the datasets and its results are shown below: The clusters were formed as shown below when the value of k was given as k = 4. The above Fig. 10 consists of 2 sections. On the right side, the original dataset is been conceptualized. Whereas the left side presents amount of data scattered after the model is trained and tested on giving value of k as 4.
Fig. 10 Clustering results for k = 4 (K-means)
That means, the model has more or less correctly classified the clusters. Although minor differences are observed when clustering the data points. But, good amount of accuracy is obtained. Table 1 Results of K-means Precision

As the data has initially 4 types of data points, and hence the value of k as 4 was best suited for it. After training the model with value of k as 4, accuracy of 96% was achieved, followed by precision, recall and F1 Score values as 0.96, 0.94 and 0.96 respectively. Whereas silhouette score was around 0.551. This can conclude ingenious results with the first try. Further after, the value of K was reduced to 2 and following changes were observed:

Although points were classified according to nearest distance, the model yielded 50% accuracy and precision, recall, F1 score as 0.3, 0.5 and 0.37 respectively. There was no prominent change observed in Calinski Harabasz Score. But the Silhouette Score was increased by 25% approximately. This was due to; the points were correctly classified according to their positional distances. But accuracy of model decreased by nearly 50% as, the data initially consists of 4 distinguished sets which can be visualized as 4 different clusters. Hence, from above observations, one can conclude that, proper selection of value of K largely affects the results and overall accuracy of the model trained.

Abstract. In AI and machine learning the process of extracting and discovering patterns in large datasets involving methods in network clustering has been extensively, studied. Clustering method are widely used for partitioned the data. In Unsupervised Machine Learning K-Means is very powerful technique. K-means algorithm calculation is a repetitive process where we try to limit the distance of data points from the approximate data points in cluster. A power-efficient for Wireless sensor network a K-means algorithm is proposed, which is utilized to enhance the performance. K-means algorithm has many drawbacks that hampering his work. In this we proposed a limitation of K-means and some suggestions. Most of the existing K-Means algorithm are there but does not provide a better performance. This performance is based on proper selection of initialization method. It is shown that how the modified k-means algorithm will build the nature of cluster and mainly it focuses on the assignment of cluster which is centroid selection so as to improve the clustering performance through K-Means clustering. There are some of the methods for initialization through which we can hypertune our algorithm to improve it. In this paper, an enhanced clustering algorithm of modified K-Means approach it has been proposed to enhance the performance of it so that we get a better accuracy. And, that we can apply on WSN applications. Keywords: Clustering · K-means algorithm · WSNs · Improve Centroid selection · Accuracy · SSE · Modified method in algorithm

By coordinating frameworks advancement in chips has welcomed a critical change in transit we see our general surroundings. The improvement of central processor has prompted the creation of little measured gadgets utilized in numerous applications, there are called sensors. These hubs are as yet being developed stage however numerous applications these days use them for their purposes. Sensor elements are not only capable of measuring a physical factor to which they are designed, but also to process and store the collected data [1].

another sensors. In request to accumulate data more efficiently, there is use of unsupervised clustering algorithm is utilized for data correspondence in wireless sensor network (WSN). The concept of Clustering has been around for quite a while and its real life example in our day to day life we uses and also came to know how these approach used to cluster our data. Clustering analysis discover clusters of data that is like one another [2] and its main principle objective for clustering analysis is to find out the high-quality cluster such that we can find the similarity and useful for exploring data. If there are finding of natural grouping because there are no obvious groupings, here clustering algorithms can be used [3]. And in WSN can be characterize as a network of wireless devices that can gather and furthermore, convey the data through the wireless links [4]. Clustering in sensor nodes is very important in order to solve many problems like scalability, energy and lifetime issues of sensor networks. It incorporates gathering of sensor centers into clusters and choosing cluster heads (CHs) for all the clusters. A Clustering helps in organizing voluminous, huge data into clusters which shows inward design of the data. Example clustering of genes. A Wireless sensor network (WSN) can be characterize as, a network of wireless devices that can gather and convey the information through the wireless links. It is a self-coordinated organization made by an enormous number of miniature sensors that are arbitrarily sent in observing territorial through remote correspondence. Bunching is one of the critical procedures for drawing out the organization lifetime in remote sensor networks (WSNs). It incorporates gettogether of sensor centers into cluster and picking cluster heads (CHs) for all of the cluster. The data is ready to be used for other AI techniques after clustering. Example: For news Summarization wherein we group data into clusters and then find centroid. For relevant information data clustering Techniques are very useful. A couple of years back there is increased in the potential use of Wireless sensor network in applications such as Environmental management and various surveillance [5]. Continuously issue, it is regularly tracked down that the assessment of the specific estimations of all the rules is troublesome and in WSN it incorporates gathering of sensor hubs into groups and choosing Cluster Heads (CHs) for all of the groups. The working of CHs is to collecting the information from specific bunches hubs and forward the accumulated information to base station, so in request to energy efficient. Clustering is well known problem which has been calculated widely used in the applications of WSN. This paper, is to define the problem of WSN where clustering include, we propose K-means which is distance based method for clustering by grouping of sensor nodes [6]. K-means algorithm—It is Clustering algorithm in which use for selection of cluster head through Euclidian distances done, after that all nodes transmit their data to a central node which save this information in a node. Then after the data are collected from all the nodes then it will performs the k-mean clustering algorithm [7]. To overcome the K-mean disadvantages we will using calculation in a smarter way for initialization [8] of the centroid and improve the behavior of the clustering. Aside from initialization, the remainder of the calculation is the same as the standard K-means calculation. That is K-means++ is the standard K-implies calculation combined with a more smarter way for the selection of centroid and also Elbow technique used to discover

the number of cluster in a right manner. Using different parameters like initialization method, accuracy, homogeneity score, Davies Bouldin score and Silhouette score [9]. After that we go through experiments for implementing K-Means with different measurement techniques. Based on the results of the experiments, we finally come to a conclusion about the performance done by modified algorithm using different parameters [10].

2 Ease of Use 2.1 K-means Generalization Benefits . We are given an informational index of things, with specific highlights, and qualities for these highlights (like a vector). The undertaking is to arrange those things into gatherings [11]. To accomplish this, we will utilize the K-Means calculation; an unsupervised learning algorithm. The calculation functions as follows: • First we introduce k focuses, called means, haphazardly. • We categorize each item, to its nearest mean and we update the mean’s directions, which are the midpoints of the items ordered in that mean up until now. • We repeat the process, for a given number of iterations and toward the end, we have our groups [12]. K-means Advantages: • • • • •
It is simple to implement. It also scales to large datasets. Guarantees Good convergence. It start with warm positions of centroids. It is easy adaptable.

• It forms Clusters into different sizes and shapes, such as elliptical clusters [13]. Drawback: One of the downside of this algorithm is delicate to the initialization of the centroid or the mean points, a random initialization of centroids resulted in poor clustering which is not suitable [14]. Clustering outliers: In all the algorithm outliers is main issue it might get their own cluster instead of being ignored. Consider removing outliers before clustering [15]. 2.2 Modified K-means (Initialization Method) A smarter initialization will improve the clustering, the rest of it remain same as standard k-mean algorithm i.e. k-means++ is used in first phase of standard K-means algorithm. The procedure for initialization, will pick up centroid that are far away from one another. The chances of initially picking up centroids that lie in the different clusters [16]. Applications of K-means algorithm: • • • • • • • • • • • •
It is used in Market segmentation. It is used in Document clustering. It is used in Image segmentation, compression. It is used in Vector quantization. It is used in Cluster analysis. It is used in learning or dictionary learning. It is used in Identifying crime-prone areas. It is used in Insurance fraud detection. It is used in Public transport data analysis. It is used in Clustering of IT assets. It is used in Customer segmentation. It is used in WSN applications.
2.3 Clustering in WSN Wireless sensor organizations (WSNs) are utilized in different applications from medical care to military. Because of their restricted, small force sources, energy turns into the most important resource for sensor hubs in such organizations [17]. To improve the use of energy assets, scientists have proposed a few thoughts from expanded points. Bunching of nodes assume a significant function in preserving energy of WSNs. Clustering approaches center around settling the contentions emerging in compelling information transmission [18]. In this part, we have plot a couple of current energy-proficient bunching ways to deal with improve the lifespan of wireless sensor network. In order to collect the data more efficiently, an unsupervised Machine learning Clustering Algorithm is used for data communication in WSN. For that cluster analysis there is a significant procedure for ordering a “mountain” of data into sensible important documents [19]. One of the clustering techniques for dragging out the network lifetime in WSN. It include the gathering of sensor hubs into clusters and CHs for all the clusters [20].

K-value—It find the optimal value for K which perform for the unsupervised ML Clustering Algorithm. When the value of K increases, result in fewer distortion. Accuracy—It measured the true value which is closer. SSE—It is full form is sum of the squared and calculated the centroid and each member of the cluster distance. As K value increases there will be decreases in disortation which will be small. Davies Bouldin Score—This defined as the score of average similarity measure of each cluster which containing its most similar cluster, it is the ratio between the withincluster distance and cluster distances similarity. For better result clusters which are farther separated and less dispersed. Homogenity Score—Its absolute value of the labels is an independent metric. It’s value for cluster label would not change in any way. For perfect labeling are homogeneous which shows its value between 0 and 1. Silhouette Analysis—It is utilized to decide the degree of separation between clusters. And it ranges in the interval between [−1, 1]. • If value 0 → this sample is very near to neighboring clusters. • If value 1 → this sample is consider when neighboring cluster is far away. • If value −1 → this sample consider that it is assign to wrong cluster.
5 Conclusion For knowing algorithm performance we have to take more parameters to know for it’s better result. Because in unsupervised there is no labelling of data. The K-means algorithm has been widely used for clustering large sets of data. Because of the performance of existing standard k-means algorithm does not always guarantee to have a good results as the accuracy because the final clusters depend on the selection of initial centroids. Moreover, the computational intricacy of the standard algorithm is questionably high owing which require to reassign the data point88s focuses a number of times, during each and every iterations of the loop. This presents an enhanced and development of algorithm which joins a systematic strategy for finding initial phase for centroids and it is an efficient way to utilize on WSN application. There is still researching for a better result the result shown above is experimenting of different datasets. Acknowledgements.

Abstract. A side channel analysis is major threat in secure communication device. Here our object is very clear to protect the sensitive information by adding DNA cryptography with chaotic countermeasure method. To overcome the side channel issues. Due to the side-channel attack can retrieve easily sensitive information from crypto embedded devices. So that the reason we need to protect the sensitive information (encryption key) in crypto embedded devices by applying the random number generation method. Mostly the random number generation used in medical data transmission, information security, and all sensitive areas. So in the research work, we apply a random generation by using the chaotic circuit. And also the paper concentrate to realize the chaotic circuit in hardware using FPGA with partially reconfigurable. And also based on Lorenz’s chaotic circuit used to protect sensitive information. Simulation and Synthesis verification done by using the VIVADO tool. Security analysis is done by hierarchical UACI, NPCR, and correlation. Keywords: Side channel attack · FPGA · Chaotic
1 Introduction Electronic trading, digital signature, multimedia communications and other areas have quickly grown with the popularity of personal computers and networks [1]. At about the same time, more and more focus is also being paid to information security issues in these areas. Most hackers are excellent at analyzing the encryption algorithm mathematically, so that they can quickly decrypt sensitive information [2]. In recent years hackers are retrieve the sensitive information through side channel power analysis attack. To overcome the above problem we need to develop a random number generation to enhance the security devices. The sensitive values will be pass through the initial condition of chaotic equation, based on the chaos initial condition it will generate random values, and it is proved that chaos exists in almost all engineering fields [3]. Further the chaos theory have been use huge areas like secure communication, image processing, filed of cryptography [4–9]. This paper organized as follows. Our contribution is two-fold. First, we suggested chaotic counter-measures with initial conditions groups for an efficient counter-measure technique includes in DNA crypto © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2022 V.

process. Second, we suggested a regional and power-centric hardware implementation for proposed chaos solution that could be deemed sufficient for the effective prevention of SCA (Side Channel Attack).
2 Cryptography Now day’s cryptography devices are prone to the hackers to retrieve sensitive information, for example military data, medical data, banking transaction. Future most of the people going use NFC (Near Field Communication Device) for money transactions. For this kind latest technology we need to have countermeasure for side channel attack. Especially by using Side channel attack via power traces to retrieves the information from secure device [10]. a. Related work Now days reverse engineering is used take the sensitive information of the crypto devices [6]. For example side channel attack is one of the reverse engineering departments, this attack based on the three categories i.e. 1. Correlation Analysis 2. Differential Power Analysis 3. Template Attack and Non-Template Attack [11–16]. Based on the above three methods, hackers can analysis the sensitive information of crypto devices using power traces [17]. Convert to the research stage of power traces to collect secure information, such as hidden PIN number; until they obtain the data they can convert into a cloning process to produce precisely the same output of the system. As a result, the majority of the papers adopted only the extraction of the key from the secured network, only with a few writers focusing on including a countermeasure using the FPGA method and all authors includes reconfigurable architecture with Test involves machine learning algorithms for classification power traces of protected computer data as a countermeasure and practice [18–25]. Based on the above survey we categorize include DNA cryptography with chaotic countermeasure method in this paper. b. DNA Cryptography We need a cryptographic device to encrypt confidential information. But recent days a reverse engineering technique used to extract confidential information from the crypto devices. The most of the paper says that DNA crypto process is more secure [26] but due to the side channel attack hackers can retrieve the sensitive information via power traces of the secure DNA devices. In general, most cryptography algorithms are so effective in mathematics, but if you know the key structure, you can easily retrieve sensitive information through side channel attack. [27], and few works are implemented regarding to mitigate the side channel attack but general structure of the DNA process is below. The sequence of DNA has been seen in this study and Used as.

Methodology FPGA Design Flow: In the FPGA design flow, we need a design specification for the first stage. Using the Verilog HDL language to incorporate and realise the hardware configuration based on the specifications. The features of the modeling process must be analyzed by Afterword using the simulation process. So simulation here is nothing but testing the functionality of

the design whether it functions properly is not based on specification using the VIVADO tool in the context of wave form as shown in Fig. 4. To verify the Verilog HDL code, we used HDL code along with test bench. Appling test patterns are used to stimulate the template on the test bench. And the next step is to grasp the specification-mentioned hardware. So, the RTL architecture is transformed into the net-list hardware relationship between the modules based on the synthesis process (Fig. 2). c.

4 Results and Comparison Analysis In Fig. 4, the action of the effects of chaotic circuit simulation using Matlab is shown. In this simulation results, it is explicitly mentioned that hackers cannot figure out what the initial values and the final values of the random actions are. So based on this random process intruder that is unable to process, confidential information cannot be tracked back by side-channel power research (Figs. 5, 6, 7, 8, and 9).

Abstract. Throughout the history, various pandemics invaded the human race deducing their existence by half or more. A brief study on the past pandemics holds the above statement true. A similar situation is being experienced in the present day, a war against an invisible enemy; the novel COVID-19 coronavirus. A statistical study of the current case helps to analyze the impact of the pandemic and take required measures and is preserved for future use in case of a similar situation. The world data of covid-19 is compared and studied graphically from the very start of the pandemic till date. Keywords: COVID-19 · SARS-CoV · MERS-CoV · H2 N2
1 Introduction Viruses are parasites at microscopic level, usually very much smaller than bacteria. Viruses, like every other parasite, cannot multiply outside of a host body. Viruses can infect animals, plants, microorganisms like bacteria and archaea. Viral diseases or infections usually occur when virus particles enter cells of an organism that are vulnerable enough for the virus to reside and reproduce [1]. CORONAVIRUS FAMILY: Coronaviruses are a subfamily of Orthocoronavirinae, in the family Coronavirida, enveloped, single stranded, +ve strand RNA viruses classified within the Nidovirales order. Pathogens of many animal species and of humans, including the recently isolated SARS-CoV are found in the coronavirus family. Almost 10 years after SARS wrecked havoc, in 2012, MERS-CoV began causing illness mainly in the Arabian Peninsula, and was later found to have infected dromedary camels. It evolved from a different bat coronavirus. MERS had a relatively higher death rate than SARS but it did not spread as much [2].

A Statistical Review on Covid-19 Pandemic and Outbreak

1.1 The Novel Coronavirus or COVID-19 The WHO on the February 11, 2020, named the Novel coronavirus- induced pneumonia, as coronavirus disease 2019 (COVID-19). The virus escalated in scale since it first appeared in December 2019 in Wuhan, China. The novel coronavirus was named as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) by The International Virus Classification Commission on the same day. Covid-19 is not the 1st grievous respiratory disease outbreak caused by the coronavirus. Coronaviruses have caused three epidemic diseases in the past two decades, which are COVID-19, SARS and MERS. Many countries have reported cases of Covid-19 around the world. The number of confirmed cases in China reached over 79 thousand, of which 2,873 were dead, and 41,681 were cured, according to the data, up to the March 1, 2020. The number of confirmed cases in other countries reached to 7,041, of which 105 were declared dead, and 459 recovered. The “World Health Organization” (WHO) declared COVID-19 was listed as the “Public Health Emergency of International Concern” (PHEIC) on the 31st of Jan-20, i.e. it is risk to all over the world and a coordinated international action taken is in need. Based on the research being carried out on covid-19 and the previous study on SARS-CoV and MERS-CoV vaccine or medicine is yet to be finalized as the newly found vaccines or medicines are not effective enough [3]. 1.2 Formation of COVID 19 Coronaviruses are enfold viruses with a +ve sense single-stranded RNA genome (26– 32 kb). coronavirus genera (α, β, γ, δ) are identified, Human coronaviruses (HCoVs) detected within the α and β respectively as coronavirus (HCoV-229E and NL63) coronavirus (“MERS-CoV, SARS-CoV, HCoV-OC43 and HCoV-HKU1”) genre. After few days (“19th-Dec-2020”) patients symptoms like suffering with cough, fever, and dyspnea with “acute respiratory distress syndrome” (ARDS) were reported in Wuhan, China, caused by an unidentified microbial infection. Virus genome pattern of 5 patients with pneumonia hospitalized from Dec-18-2019 to Dec-29-2019, led to discovery of new β-Covid strain altogether. The newly found novel β-Covid that has been isolated is 88% identical to the pattern of two bird family, batderived SARS with likely corona viruses, bat-SL-CoVZC45 and bat-SL- CoVZXC21 are about 50percent identical to the pattern of MERS-CoV. The worldwide Virus Classification Commission then renamed novel β-CoV to “SARS-CoV-2”. The phylogenetic tree structure of SARS-likely corona viruses complete genome sequences is clearly depicted in the Fig. 1. In China it was discovered by several researchers and scientists that SARS-CoV-2 necessary need of ACE-2 (“angiotensin-converting enzyme 2”) as a receptor to enter cells just like SARS-CoV. The most significant factor for viral infections and diseases is the attachment of the virus with the receptors of the host cells. SARS-CoV plausibly emerge from bats, spread to other species ACE-2 and spread species to humans. DPP4 (“Dipeptidyl peptidase 4, also referred to as CD-26) was detected as a functional receptor for diseases MERS-Covid, due to receptor binding the S1 domain of the MERSCovid spike protein was co-purified with DPP-4 explicitly from lysates of susceptible Huh-7 cells. MERS-CoV can bind DPP-4 from different species, which promotes the

transmission to humans and other species, and effected cells from an outsized number of species [4]. 1.3 Symptoms Symptoms of COVID-19 are visible in two to Fourteen in days after subjected to virus either of directly/indirectly. Fever, frog-in-one-s-throat, shortness of breath or difficulty in inhalation are the symptoms that are visible in a person infected by the virus, Other symptoms may be tiredness, aches, runny nose and sore throat. In some people there might be no signs of symptoms at all. The symptoms of COVID-19 can range between a severity level of very mild and severe. Old age or who are suffering from lung disease, diabetes, heart disease and who have a bad immune system may have a higher chance to be effected by the virus [5]. 1.4 Treatment for outbreak of virus COVID-19 It is quite same situation and earlier like SARS-Covid and MERS- Covid currently availability of vaccine does not exist for SARS-CoV-2 infection. The health care department are used to treat the effected include oxygen therapy and to cover secondary bacterial infections a wide range of antibiotics are used. Plasma therapy effective in some cases, showed satisfactory results. It is not considered as an idle way to treat covid-19 worldwide. When new medicines or vaccines are being tested it should strictly follow the specifications set by each Health organizations of respective countries and that it should pass all the previous phases test [6].
2 Literature Survey Sixth cholera (1899–1923): Cholera is a nature borne disease from water that ejected from a bacterium that is said to be Vibrio cholerae. India is the first to experience an outbreak of the disease, later Middle East, North Africa, Eastern Europe and Russia observed similar outbreaks. An estimated 8,00,000 were killed by this pandemic. Someone who was in close contact with the effected or the disease, may experience symptoms such as extreme dehydration, diarrhea, and vomiting [7]. Hong Kong flu: The global outbreak of the influenza virus first started in China which is the origin of the flu. The virus’ H3 N2 subtype, the cause of a previous influenza outbreak is suspected to be where the pandemic was evolved from. One million people were killed by this virus. The factor that facilitated its rapid spread around the globe is that the virus was highly contagious. Five hundred thousand cases had been reported within two weeks in Hong Kong. The virus later escalated rapidly throughout Southeast Asia. Respiratory symptoms typical of influenza, symptoms like muscle pain, chills, fever, and weakness were caused by the infection. People infected by this virus suffered from these symptoms for around a week. In the group of highly susceptible are infants and the elderly and were related to the group of highest levels of mortality. Only after the pandemic had peaked in many countries, a vaccine had been developed and became available [8].

Asian flu (1957): The pandemic of the late 1950s, avian influenza (Asian flu) outbreak that spread and later became non-existent after a vaccine was introduced. Two million people died from this pandemic at its peak. It is recorded that a virus called as influenza. A subtype H2N2 is the cause of this widespread outbreak. Research has specified that virus is mix of the genetic material of a species into new combinations in different individuals, starting from strains of human influenza viruses and avian influenza. The virus spread throughout China and its surrounding regions in the initial months of the 1957 flu pandemic. Some individuals who were infected experienced only minor symptoms, like mild fever and cough, others experienced fatal complications like pneumonia. Protective antibodies were believed to be embedded in the ones who were unaffected by the virus. The mortality and spread of the Asian flu epidemic occurring worldwide had been limited by the fast express development of a vaccine and availability of antibiotics [9]. Spanish flu (1918): This flu was one of the deadliest flu outbreaks in history. The Spanish flu killed over 50,000,000 people and infected about 500,000,000. It was one of the deadliest flu outbreaks in history. The widespread outbreak was caused by the H1N1 virus. It is reported that spread of disease was mainly caused by excessive intake of patients and poor hygiene of hospitals. Europe was the first to report cases of the Spanish flu. The United States and Asia were reported to found cases of the virus before it escalated to other parts of the world. During the time of the pandemic, there were no vaccines or drugs to treat this fatal flu. People were ordered to cover their face using a mask, schools, other educational institutions, entertainment centers and other public places were shutdown. The deceased were either buried or cremated. The respiratory system was mainly attacked by the flu. This strain of virus was highly transmissible: when a person affected by the flu, sneezes, talks or coughs, the droplets of saliva are passed on by air, and when inhaled by anyone nearby the flu is transmitted to the other. A person can also be infected if he or she comes in contact with the virus contaminated objects and then touches their nose, eyes or mouth. Around five hundred thousand people worldwide are estimated to die from the illness during a typical flu season as reported by WHO. Up to 40% of the world’s population were sickened by this deadly pandemic that began in the year 1918 and killed an estimated 50,000,000 lives [11, 18]. EBOLA VIRUS: The Republic of Sudan and the Democratic Republic of Congo were the first to observe the outbreak of Ebola in 1976. In the early 2014, the outbreak began in West Africa. Touching with blood or tissue from infected people or mammals or other body fluids causes the spread of Ebola. As reported by WHO this outbreak is the most complex wave of the disease [12]. HIV: HIV may be the deadliest virus of the modern world. It is still the biggest killer. An estimated 32 million people were killed by HIV since it was first recognized in the early 1980s. People infected with HIV can now live for years, all thanks to the powerful antiviral drugs. Many under developed and developing countries are still struggling because of the disease. 95% of new cases are reported in such countries. In the African region under WHO nearly 1 in every 25 adults is reported HIV-positive, which accounts nearly two-third of the people living with HIV in the world [15].

SMALLPOX: The World Health Assembly declared that there were no new cases of smallpox reported in 1980. Prior to the development of vaccine, about 1 in 3 of those who were infected died from this disease. Lasting scars and, decline in eye sight were the after effects of the disease. Higher death rate was observed outside of Europe. From research it is known that the virus was contained within Europe before tourists from Europe carried it to other regions. Historians estimate that 90% of the native Americans died from smallpox which was brought in by the tourists from Europe. A total of 300 million people were killed by then fatal disease in the twentieth century [16].
3 Statistical Analysis Datasets from WHO and world meters are taken for the analysis of the covid-19 current status around the world. The dataset gives the following Attributes: Country—Countries effected by covid-19, Cases-cumulative Total—The total number of cases in each country respectively, Cases—cumulative total per 1 million. Total no population—total number of cases per one million population for each country respectively, No of Cases—newly reported in last 7 days, in last 24 h, Total no of Deaths— cumulative Total—total number of cases reported till date, Deaths—cumulative total per 1 million population, Deaths—newly reported in last 7 days, Deaths—newly reported in last 24 h (Table 1). The datasets used are: https://covid19.who.int/table https://www.worldometers.info/ coronavirus/. Graphs and statistical analysis: https://github.com/HepsibaKanaparth/COVID-19Statistical-analysis.
4 Results and Discussion From the statistical analysis of the above mentioned dataset the following are the results observed: United States of America is at the top of the list with the most reported case in the world i.e. 16,245,376 cases, it also stands first for the total no of deaths recorded with 298,594 cases. Figures 2 and 3 India takes the second place for the total no of cases recorded i.e.9,932,547 cases Fig. 2, where as Brazil takes the second place for the most no of deaths recorded with 181,835 Fig. 3. USA has the most no of cases reported in the past week and the past 24 h with 1,489,380 and 204,281 respectively also the no of deaths reported in the past week (17,152) as well as the past 24 h (1754) Fig. 7. After USA, Italy has the most no of deaths reported in both, past week and past 24 h: 4617,846 respectively Figs. 6 and 7. From studying the dataset it can be said that the most transmissions had occurred due to community transmission Fig. 12. Afghanistan has the least number in all the fields in the analyzed dataset with zero cases and deaths reported. Surprisingly the origin of the covid-19, China is listed at 74th place in the world dataset with only 779 recently reported cases and 11 reported deaths (Figs. 2, 3, 4, 5, 6, 7, 8, 9, 10, 11 and 12).

Performance Evaluation of Secure Web Usage Mining Technique to Predict Consumer Behaviour (SWUM-PCB) Sonia Sharma(B) and Dalip Department of MMICT&BM, Maharishi Markandeshwar Deemed to be University, Mullana (Ambala), Ambala, Haryana, India [email protected]
Abstract. In the changed scenario of e-commerce, not only the number of visitors but also the frequency of their visiting the site, browsing information is increasing day by day. So investigating client’s conduct is a significant piece of web architecture which is helpful for decision making, planning sites as indicated by the client’s needs. To understand and handle consumers’ web behaviour, web usage mining (WUM) is used which includes data preprocessing and pattern discovery. For pattern discovery, Apriori algorithm is selected as standard of the study. Apriori algorithm isn’t just the primary utilized affiliation rule mining procedure yet also the most well-known one. After threadbare analysis, it came to the fore that the conventional Apriori algorithm suffered from two serious flaws. Firstly, it keeps filtering the database again and again and thereby generating, unnecessarily, enormous number of rows. Secondly, it lacks the foolproof system of security of data. The proposed algorithm (SWUM-PCB), which has been accomplished on genuine information of website by utilizing Hash table, Hashing Encryption (Message Digest algorithm MD5), association rule mining has a marked edge over the conventional Apriori algorithm. Not only its effectiveness and security of information is unquestionable but also its accuracy in predicting the consumer’s future conduct is found to be unparalleled. Experimental results to find a performance evaluation of the proposed approach will present better results on real weblogs (raw data) of a website in less execution time, memory usage, less number of rows, calculation cost and less searching time to predict the result. Keywords: Consumer behaviour · Performance evaluation · Weblogs · Security
1 Introduction In the present day, the World Wide Web proved as a benchmark for all the consumers all over the world to access meaningful, purposeful information of their interest and gives all types of services such as online education, traveling guide, e-government, etc. It also provides various cradles to obtain data for mining. Web mining [1–3] acts as an umbrella to extract useful information and discover the information from the web. It consists of three methods such as web structure mining (WSM), web content mining (WCM) and © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2022 V. E. Balas et al.

web usage mining (WUM) [4–7]. To predict and identify user behaviour is an important activity in web usage mining. It is also known as weblog mining and this method is mainly used by many organizations to predict consumer browsing behaviour [8–11] & website personalization. Behaviour of consumer is analyzed from patterns generated from the weblogs [12, 13]. Association Rule mining is used to uncover the relationship among data. It identifies the exact association between the data. In the present scenario, association rule methods are searching the data as per the support count. In web usage mining, association rules means accessing of the set of website pages together with minimum support count [14]. For association rule mining, Apriori algorithm is most widely used algorithm by the organizations. After ragged scrutiny, it came to the fore that the Apriori algorithm grieved from two grim problems. Firstly, it keeps filtering the database again and again and thereby generating, unnecessarily, enormous number of rows. Secondly, there is not a concept of security of data. In the field of web utilization mining, analyst utilizes the numerous calculations and check the exhibition assessment with existing (Apriori) calculation yet just on information accessible free or little thing set, for example, mushroom/pumb set dataset and some applies the security yet just for the protected information communication [15]. The proposed algorithm (SWUM-PCB) which has been accomplished on genuine information of website www.viralsach.xyz1 by utilizing Hash table [16, 17], Hashing Encryption (Message Digest algorithm MD5), encoding and decoding, Apriori property & anti-monotonicity has a marked edge over the conventional Apriori algorithm. The Proposed algorithm not only gives the assurance of security of data [18–20] but also predict the consumer behaviour in an efficient way. The Message Digest (MD5) algorithm [21, 22] is utilized for expanding the nature of the whole framework through the age of the encoding and unraveling the information made sure about keys and in this manner the real information is made sure about with more effectiveness and keep up the uprightness of information and furthermore fulfill the property of secrecy, non-disavowal and approval. In this paper, section-II shows the previous work done by researchers in the arena of web usage mining and generating frequent patterns. Section –III describe the existing Apriori algorithm of data mining which is used to find an association between the data. Section-IV presents the proposed algorithm (SWUM-PCB) which is designed to predict consumer behaviour on real data (weblogs of website). Section-IV presents the experimental results and performance evaluation of the proposed algorithm with the existing algorithm.
2 Literature Review The discovery of hidden pattern is most important activity of web usage mining. Numbers of researchers done a lot of work in this field and have applied many techniques on processed data for pattern discovery. In [23] authors used the clustering technique to find user interest among the website pages [24]. The authors deliberately present the usage of access patterns and show the difference of technology boom in the field of web usage mining [15]. To find the best hit ratio, the authors proposed a fuzzy probabilistic algorithm and two-levels of predicting model is designed by the authors [25].

authors introduced a new technology for horizontal and vertical segmentation of data and apply the Diffe-Hellman algorithm [25]. Authors emphasized the technique of web usage mining and also explain the benefits of data collected in the form of weblogs [26]. Custom built Apriori algorithm is proposed by the authors to find the pattern to know the consumer browsing behaviour.
3 Apriori Algorithm This algorithm is known as an influential and classical algorithm [27, 28] to generate association rules in data mining. It is used for mining frequent item sets. The Pruning technique is used in Apriori. The first pruning technique is based on the support count and the second is based on the frequent item set. It follows the closure property of frequent item set i.e. if A is the set of Frequent Items then its proper subset is also frequent. Steps of Algorithm A1 = {list of frequent items}; For (r = 1; Ar! = r + + ) do for each transaction t in required database do Increment the count of all candidates in Cr + 1 that are contained in t Ar + 1 = candidates in Cr + 1 with min_support Returnr Ar;
4 Proposed Architecture The proposed architecture is shown in Fig. 1 proposed work is divide into mainly four steps. A lots of raw data is stored on the web server. Firstly data is collected and converted into.csv format for the study. After that pre-processing of data is done, after getting processed data, proposed secure pattern discovery algorithm is applied to generate patterns. At the last step analysis of pattern is done for the prediction of consumer behavior.
5 Proposed Algorithm This study proposes a Secure Web Usage Mining Technique (SWUM) for the prediction of consumer behaviour. In SWUM algorithm, Hash based approach with Message digest algorithm and association rule mining are used together. The Hash Based approach decreases the size of candidate set through filtering any k-item set whose corresponding hashing count below the threshold and instead of scanning whole data base only those items to be scanned that occurs frequently. Use of MD5 secure the data (data integrity) and also it compress the data and encoding and decoding the data is done in the proposed

The experimental runs have been conducted on different data set i.e. Data set I, II, III & IV (shown in Table 1) at various minimum support count &taking some parameters in consideration such as Data security (data integrity, confidentiality, non-repudiation, authorization, Availability, data Freshness), execution time, memory usage and predicting of consumer behaviour in terms of generating rows under consideration.. Results obtained are very large so in this paper some of the results are shown of two different sized datasets. It has been found that the proposed algorithm always takes less time than basic Apriori and the interesting information can be mined in a shorter time. Difference in execution time for data set –I and data set-II is shown in Figs. 2 and 3. It is shown in Fig. 2, Time taken by Apriori algorithm is very high as compared to Proposed algorithm. At minimum support level 50, Apriori algorithm takes 3998.453 s where as proposed algorithm taken only 52.29 s. Similarly at minimum support 80, SWUM-PCB takes 20 s only which makes proposed method as an optimum solution. SWUM-PCB takes less execution time for data set-II consisting of 10,567 rows as shown in Fig. 2. It takes 10.19 s at 50 minimum support count and Apriori algorithm takes 558.39 s. Figures 4 and 5 depicts the difference in memory usage by both algorithm for data set-III & IV. Due to use of hash table and Md5 which compress the data and maintain the security of data and thus increase the efficiency of proposed system and give the result in less time. So also provides results in less memory usage. For checking of memory usage, memory function is applied on both algorithms which shows less processing time and memory usage. Figures 6 and 7 shows the difference in time and generating number of rows for different data set at best minimum support count. If minimum support threshold set

Increasing amount of records, Apriori algorithm takes longer time to generate frequent item set as compared with proposed method. After selecting best minimum support count, the difference in time, memory and generating number of rows for prediction of consumer behaviour is obtained. Prediction of consumer behaviour and generating frequent pattern by the proposed algorithm (SWUM-PCB) is very efficient and give high

The conventional Apriori algorithm is used by the many researchers but it takes more execution time and more memory usage.

The proposed algorithm (SWUM-PCB) i.e. secure web usage mining technique to predict consumer behaviour is very simple for producing the secure, efficient, accurate, fast results in comparison to the existing algorithm. The existing algorithm relies on mathematics so it is less robust. In the proposed algorithm, there is no need to maintain the separate database and no need to mine the data separately. As the technology is changing day by day, our proposed system contributes high robustness and can cope up with the advancement of technology.

Abstract. Quantum Computing is new standard which will contribute computational efficiency on to the many operational methods of classical computing. Quantum computing motivates to use of quantum mechanics such as superposition and entanglement for making new standard of computation which will be far different than classical computer. The quantum computing concept need to understand Qubit which is nothing but Quantum Bit that differs quantum computing from classical computing. Classical bit, which can be either Zero 0 or One 1 in single state at a time moment, a Qubit or Quantum Bit can be Zero 0 and One 1 at same time called as in superposition state. Quantum Computers will use quantum superposition and quantum entanglement are the two basic laws of quantum physics principles. Computational tasks which are non-computable by classical machine can be solved by quantum computer and these computational tasks defines heavy computations those expects large size data processing. Machine learning on classical space is very well set but it has more computational requirements based on complex and high-volume data processing. This paper surveys and propose model with integration of quantum computation and machine learning which will make sense on quantum machine learning concept. Quantum machine learning helps to enhance the various classical binary machine learning methods for better analysis and prediction of big data and information processing.

has some computational difficulties in terms of operational methods of classical computer. Proposed techniques in quantum computing domain will overcome computational difficulties and represent data on very high dimensional feature space by making use of quantum mechanisms. Quantum mechanics such as superposition and entanglement will help to represent and process data on higher dimensional space which will make sense of how quantum machine learning will reproduce better results over classical ml methodologies. To understand quantum concept, we should be brief on following points: Quantum Qubit, Superposition, Entanglement. The benefits of quantum computers motivate the standard by introducing qubit or a quantum bit, the Quantum information called as Quantum bit. Single number has 0 or 1 used to represent the state of a bit on a classical computer. So classical bit can be having state 0 and 1 at one-time moment. Classical binary data and information is string of zero 0 and one 1. An atom might represent a quantum bit and electrons, photons will be used for state formation of qubit. Qubit is a powerful bit having multiple states within it based upon superposition and entanglement principle.1 qubit is in having two different states, which can also be denoted as 0 and 1 at same time moment. 2-qubits can have 4 states as (00, 01, 10 and 11) at same time moment. Similarly, 3-qubit has 8 states as (000, 001,010,011,100,101,110,111) at the same time and so on for n-qubit the states will be 2n. Quantum mechanism is motivation behind proposed quantum machine learning. Quantum mechanism will have benefits on operational limits of classical computers. The probability for each state is α and β. Two-qubit quantum computer thus requires four amplitudes. Quantum Bit or Qubit on Classical Computers, data and information of data is in terms of Classical 0 s and 1 s, and the concept that carries such information is called a “bit” or called as ‘ON as 1’ and ‘OFF as 0’ bit. A Classical bit can be in either a 0 or 1 state at any one-time moment. A quantum computer proposed new standard in terms of mechanism that is a quantum bit or “qubit” instead of a classical bit 0 and 1. A quantum bit will make use of two states (0 and 1) to represent data and information, but bit will hold single state at a time moment and a qubit can take together states of 0 and 1 simultaneously at any one moment is called as superposition. In similar way, two qubits in this state can provide the four values of 00, 01, 10, and 11 all at one time and 3-qubit can have eight states such as (000,001……111). Bloch sphere is single qubit representation as shown in diagram. Bloch sphere represents 1 qubit space in which electron will spin in up position is activation state represented as ‘1’ and electron spin in down position will represented as ‘0’. Sphere representation of Qubit is well known as the Bloch sphere, and it will visualize the state of a single qubit. Figure 1 shows 1-qubit Bloch sphere representation with real value amplitudes [1]. Superposition Atom is tiny and very small chemical particle which will change the whole definition of classical to quantum mechanism. Data on classical machine is represented by a single atom that is represented in states denoted by |0 > and |1 > . A bit with composite state is known as a qubit nothing but Quantum Bit. Qubit implementation utilizes the atom energy levels is called as superposition mechanism which definitely makes comparison between classical and quantum Machines. Electron spinning up direction is excited state represented as |1 > and a ground and null state representing |0 > A single or 1- qubit is

is superposition of two states 0 and 1 for 1 qubit accordingly state will measured for multiple qubits as per mechanism. Equations 1, 2 ,3 represents 1qubit, 2qubit, 3qubit. 2- qubit state is represented in following manner, four states and shown in Fig. 2 = α1 |11 > + α2 |01 > + α3 |10 > +α4 |11 >

Entanglement Quantum entanglement is one the fundamental and strong quantum physics mechanism of quantum systems to define correlations between states within a Superposition. Qubits cannot be separated once they are getting entangled with each other. after entanglement on multiple particles Qubits are going to behave and react with each other as per their entangled rule which is applied. Figure 2 shows quantum entanglement for 2 qubits and which is the superposition of four states. Quantum entanglement is one of principles of quantum physics, and which is really very complex to understand. Entanglement which is Linking of multiple qubits together to show superposition states on higher dimension. Qubits are entangled with each through the action of laser to connect them. Once after entanglement they are in intermediate state of behavior with each other. But then after qubit can separated with any distance but they will be remaining entangled with each other. Quantum gates Quantum gates are used to represent states and superposition between the qubits. Quantum computing will use logic gates and these gates are having different purposes. Like, Hadamard gate will gives superposition of 1qubit, Pauli-X will require to rotate in xdirection, also Pauli-Y will rotate in Y-direction. Controlled Gates will work on 2-qubit and more to measure second Qubit. Table 1 shows quantum gates overview and what will be the input provided to the gate have shown [1]. Table 1 Quantum gates Gate

Quantum computing will perform such tasks which classical computer cannot on operational ability of machine. Quantum machine learning is capable to consider higher dimension feature space such as n-dimensional feature space. Classical machine learning can plot data on multiple dimensions but it would take more time and sometimes it will fail on operational power of system. Quantum Machine learning will perform complex analysis and prediction in terms of weird pattern generation. Complex and high dimensional pattern generation will be not possible on classical machine at some extent. Quantum ML

Quantum computer can analyze vast amount of data and predict certain result in very less time in comparison with traditional computers such as digital and high-performance computers. These machines are still taking longer time to predict accurate analysis. By proposing quantum machine learning algorithm, the model which will predict pattern in very short time with excellent accuracy. Quantum machine learning will help to generate and model system which will give faster result on classical machine.
3 Quantum ML Research Domains Quantum Whether Forecasting: In this application dataset formation will be on real time basis. also forecasting data will be required real time processing which will predict result in faster manner. This application currently using GPU processing. forecasting will process and analyse Rain, Temperature and other climate related data. This real time data has very big size so processing will be also time consuming. Quantum computing in whether forecasting would overcome this difficulty in computations. Drug Discovery: Quantum computing and machine learning will be playing very important contribution in this field also. Quantum Satellite Image Processing: Image processing will be best set classical application also giving good performance on supercomputers. But there are certain image types those are very big size such as Satellite images. Quantum satellite image processing would be more time efficient. Quantum Social network data Analytics: Data gathered on various social networking sites such as Facebook, Twitter, Instagram will have vast volume. Not only text data analytics but also multimedia data analytics on real-time basis can be made. Quantum computer can also take challenge to process this type of data. Disaster Management: Disaster data such as Earthquake, Flood, Land Sliding requires before time predictions. Quantum computer can really do its good in it. Cryptography: There is lot of research happened in past two decades in cryptography. CPU and GPU are currently involved and contributed in various cryptography techniques [2]. 3.1 Survey on Quantum Literature Ablayev and Ablayev [3] in 2019 have proposed quantum methods for ML and also highlighted on available quantum tools in initial part of paper.

Ablayev et al. [4] proposed in as continuous research on [3] on quantum ML tools. F. Ablayev and M. Ablayev surveys QML for classification and discusses the quantum nearest neighbor algorithm (NN) algorithms. Next section highlights the QNN algorithms gives quadratic time speed-up over classical algorithms. Quantum neural network is beneficial on time scale compare to classical NN. Literature review in this paper consist of two parts, quantum tools”, here it presents some fundamentals and several quantum tools based on Grover search quantum algorithm. Grover search is well known quantum search algorithm. Second section of paper discusses classification in ML that that can be enhanced with quantum technology. This paper enlightens supervised learning algorithms as classification to elaborate and speed up by the use of quantum tools. Yangyang et al. [5] Quantum information processing, Molecular science, and atomic physics will require robust control design and which is key task in quantum technology. In this paper, multiple samples and mixed-strategy DE (msMSDE) algorithm is proposed. This algorithm is also called as improved dimensional algorithm. Proposed problem will search fields for quantum control parameters. In this algorithm (msMSDE), is highlighting on mutation operations. Fitness evaluation method for mutation operation requires to use multiple samples and its mixed strategy for performance measures. Author wants to convey that the msMSDE algorithm is best fit for control problems. This work discussed the Optimal universal quantum machine’s performance. Proposed research is using quantum qudit which quantum partical on n-number of states. Qudit is more powerful than qubit. The state discriminating of a qudit is begins from a set of templates states collected. Training set which is used is classically available and requires some global information for processing data. Realistic modelisation approach is quite hard to make up. Quantum state absolute information is not accessible because of random states of qubit. Structural properties of quantum states are available. Scenario is explained with quantum communication. In Quantum communication, receiver is unaware of transmitted state, but has classical knowledge on the code used by the sender.

1 Introduction Data Analysis and Forecasting on Supermarket Sales Transactions which focus on the betterment of the sales in the business. We are presently observing solid outcomes from organizations that utilize Machine Learning (ML) as well as Artificial Intelligence (AI) to surpass their opposition and close more arrangements. In fact, sales teams that adopt these tools are seeing an in drives what’s more, plans of over half and cost diminishes of up to 60%, as showed by the Harvard Business Review. Here are just a few of the

possibilities like interpret customer data, Improve sales forecasting, predict customer needs, Efficient transaction sales. For data analysis, we from the outset handle the information. So In Statistics, EDA (exploratory data analysis) is used to: Better understand the data, build an intuition about the data, generate hypothesis, find insights, Visualization [1]. After the visualizing the data we used RFM (recency, frequency, monetary) analysis to segment the customer. The RFM model estimates when individuals buy (Recency), how frequently they buy (Frequency) and the amount they buy (Monetary). While past procurement of customer can suitably anticipate their future purchase direct, association can recognize which customer is praiseworthy. To figure RFM model score we will apply K-mean bunching [2]. But we should tell how many clusters we need to K-means algorithm. To find it out, we will apply Elbow Method. Elbow Method just tells the ideal group number for ideal dormancy. For better understanding of the result we can see the mean value of Recency, Frequency and Revenue represent. With we can segment the data on the filter of low-value, mid- value and high-value. After RFM Score we need to recognizes the strength of relationship between sets of item bought together and distinguish examples of co-event, for that we use Market Basket Analysis (MBA). A co-event is when at least two things happen together. For beneficial outcome in MBA we measure the strength of a rule by calculating the following matrices like Support, Confidence and lift [3]. After MBA we investigate deals exchange information for item racking by Apriori Algorithm [4]. Time arrangement estimating has been shown practical in sensible dynamic in various spaces [5]. Right now translating beyond facts or enjoy into forecasting of factors to come. Due to the seasonal fashion of time collection used, the Seasonal ARIMA (SARIMA) is selected for the version development [5].
2 Problem Statement The present questionable economy, organizations are attempting to receive elective approaches to stay serious. Distinctive incapable determining strategies lead to various item stock outs. So research revolves around (company size, stakeholders, solutions they want) different forecasting techniques for demand prediction through machine learning have the ability to compare it to historical sales efforts. The proposed framework can come to an obvious conclusion and better foresee what arrangements would be viable and the probability of the arrangement shutting and to what extent it will take. This understanding enables deals the executives to more readily apportion assets and anticipate deals projections.

3.1 Exploratory Data Analysis (EDA) In EDA (exploratory data analysis) the first sign that a visualization is good is that it shows you a problem in your data, detect outliers or anomalous events and find interesting relations among the variables [6]. Dataset Understanding (Fig. 2). Added a column Invoice Year Month to have a month wise view of the data (Figs. 3 and 4). A genuine model can be used or not, yet essentially EDA is for seeing what the data can exhort us past the ordinary showing up or hypothesis testing task [7].

3.2 RFM (Recency, Frequency, Monetary) Model For a fruitful business, taking part in a powerful battle is a key assignment for advertisers. Customarily, advertisers should initially distinguish showcase division utilizing a scientific mode and afterward execute an effective battle intend to target gainful clients [8]. Proposed system was expected to used RFM (recency, frequency, monetary) concept to segment customer [9]. RFM method is used to analyzing customer value. It is generally utilized in database promoting and direct advertising and has gotten specific consideration in retail and expert administrations ventures [10]. This investigation proposes utilizing the accompanying RFM factors: • Recency(R): at the point when individuals purchase. • Frequency(F): how frequently they purchase. • Monetary(M): the amount they purchase. In RFM model apply K-implies grouping to allot a score to the client [11]. Nevertheless, ought to instruct what number with respect to bunches we need to K-implies calculation. To find it out, it will apply Elbow Method. The elbow methodology runs

k-suggests gathering on the dataset for a degree of qualities for k (state from 1–10) and from there on for each evaluation of k cycles a common score for all groups [12] (Figs. 5, 6, 7, 8, 9 and 10).
Fig. 5 Calculating Recency for each customer
3.3 Market Basket Analysis (MBA) Market Basket Analysis (MBA) is a standard instance of affiliation rule mining. Market Basket Analysis makes If–Then circumstance rules, for example, if thing An is obtained, by then thing B is likely going to be purchased. The guidelines are probabilistic in nature or, in a manner of speaking, they are gotten from the frequencies of co-occasion in the discernments [13]. Among every one of the strategies for information mining, apriori algorithm is seen as better for association rule mining [14].

The key idea in the Apriori algorithm is that it accept all subsets of an incessant itemset to be visit [15]. Similarly, for any infrequent itemset, all its super-sets must also be infrequent. In order to select the interesting rules out of multiple possible rules from the business, proposed system is using the following measures [16]. Support: The ensuing measure called the sureness of the standard is the extent of the amount of trades that remember all things for {B} just as the quantity of exchanges that remember all things for {A} to the quantity of exchanges that remember all things for

Confidence: The ensuing measure called the sureness of the standard is the extent of the amount of trades that remember all things for {B} just as the quantity of exchanges that remember all things for {A} to the quantity of exchanges that remember all things for {A}[17]. Confidence = (A + B) / A

Lift: The third measure called the lift or lift extent is the extent of certainty to expected certainty. Expected certainty is the certainty partitioned by the recurrence of B. The Lift discloses to us how much better a standard is at anticipating the outcome than simply accepting the outcome in any case. More noteworthy lift esteems show solid er affiliations [18] (Fig. 11).

3.4 Time Series Forecasting Time-series techniques for estimating. Forecasting is a strategy or a method for assessing future parts of a business or the activity. It is a technique for interpreting past information or experience into assessments of things to come [19]. Time arrangement includes the utilization of information that are filed by similarly separated increments of time (minutes, hours, days, weeks, and so on) Because of the discrete idea of time arrangement information, time arrangement informational indexes have an occasional as well as pattern component incorporated into the information [20]. The initial phase in time arrangement displaying is to represent existing seasons (a repeat ring design throughout a fixed timeframe) as well as patterns (upward or descending development in the information). Representing these installed designs is the thing that we call making the information fixed. Arrangement is supposed to be fixed arrangement if and just if the joint likelihood is doesn’t change over the long run that is the mean and fluctuation of the arrangement stay consistent over the long haul [21].

165
With moving information, as time increment the mean of the arrangement either increments or diminishes with time (think about the consistent expansion in lodging costs after some time). For occasional information, the mean of the arrangement varies as per the season (think about the increment and diminishing in temperature like clockwork) [22] (Fig. 12).

One step ahead forecast uses the actual value for each subsequent forecast (Figs. 13 and 14).

There are two strategies that can be applied to accomplish stationarity, contrast the information or straight relapse. To take a distinction, you ascertain the distinction between successive perceptions. To utilize direct relapse, you incorporate double marker factors for your occasional segment in the model [23]. 3.5 SARIMA (Seasonal Autoregressive Integrated Moving Average) Autoregressive Integrated Moving Average, or ARIMA, is a guaging technique for univariate time arrangement information. As its name proposes, it upholds both an autoregressive and moving normal components. The coordinated component alludes to differencing permitting the technique to help time arrangement information with a pattern [24]. An issue with ARIMA is that it doesn’t uphold occasional information. That is a period arrangement with a rehashing cycle [25]. ARIMA expects information that is either not occasional or has the occasional part taken out, for example occasionally changed through strategies, for example, occasional differencing [26]. SARIMA technique is time arrangement anticipating strategy for stochastic model information with occasional information design [27]. • ARIMA (p, d, q): The non-occasional piece of the model • SARIMA notation is (P, D, Q) s: The occasional piece of the model • s: Seasonal factor Seasonal Autoregressive Integrated Moving Average, SARIMA or Seasonal ARIMA, is an expansion of ARIMA that expressly upholds univariate time arrangement information with an seasonal segment [28]. It adds three new hyperparameters to

determine the autoregression (AR), differencing (I) and moving normal (MA) for the occasional segment of the arrangement, just as an extra boundary for the time of the irregularity [29]. Time series forecasting of Germany (Figs. 15 and 16):

One step ahead forecast utilizes the real incentive for each ensuing estimate [30]. The Mean Squared Error of our forecasts is 1607357.8. Dynamic forecast utilizes the estimation of the past forecasted estimation of the reliant variable to register the following one [32] (Fig. 17). The Mean Squared Error of our forecasts is 1648114.76 (Fig. 18).

Step 5: Assign Score to the customer using K-means Algorithm. Step 6: Utilized Market Basket Analysis Technique to recognizes the strength of affiliation. Step 7: Distinguish the relationship between sets of items bought together. Step 8: Distinguish examples of co-event. Step 9: For better association rule mining apply apriori Algorithm. Step 10: Visualize the time series. Step 11: Stationaries the data. Step 12: Build SARIMA Model for seasonal component. Step 13: Make The prediction of the data.
5 Conclusion This paper portrays the procedure of Forecasting in detail. In experiences, EDA is an approach to manage separating educational assortments to summarize their rule ascribes, consistently with visual methodologies. It is allude to performing introductory examinations on information to find designs, to spot oddities, and to check supposition with the assistance of summery insights and graphical portrayals. There is a better understanding on which customers are priority and which are not and have better understanding what action are required on low priority customer to improve sales. It would seem that 3 is the ideal one dependent on business necessities. We can proceed with less or more bunches. Now its shows products are mostly bought in pairs, which can enable the business at store level to sell these product side by side in store to improve furthermore sales. further this model was regularized, market basket analysis on France from the Dataset then use these finding to improve sales by pairing up the frequent bought items together. The precision of the regularized model was discovered to be in the sell 340 Green Alarm tickers yet just 316 Red Alarm Clocks. so perhaps it can drive more Red Alarm Clock deals through proposals. Accordingly it is presumed that SARIMA gives precise consequences of figures and can be utilized for foreseeing the deals of store on Germany information utilizing One stride ahead conjecture of genuine incentive for each ensuing estimate and the Mean Squared Error of our gauges is 1607357.8. At that point Dynamic estimate utilizes the estimation of the past gauge estimation of the reliant variable to figure the following one. The Mean Squared Error of our conjectures is 1648114.76. In spite of the fact that picking of the model for determining will absolutely rely upon the kind of dataset.

Abstract. Today, for Internet users, micro-blogging has become a popular networking forum. Millions of people exchange views on different aspects of their lives. Thus, micro blogging websites are a rich source of opinion mining data or Sentiment Analysis (SA) information. Because of the recent advent of micro blogging, there are a few research papers dedicated to this subject. In our paper, we concentrate on Twitter, one of the leading micro blogging sites, to explore the opinion of the public. We will demonstrate how to collect real-time Twitter data and use algorithms such as Term Frequency-Inverse Document Frequency (TFIDF), Bag of Words (BOW) and Multinomial Naive Bayes (MNB) for sentiment analysis or opinion mining purposes. We are able to assess positive and negative feelings using the algorithms selected above for the real-time twitter info. The following experimental evaluations show that the algorithms used are accurate and can be used as an application for diagnosing the depression of individuals. We worked with English in this post, but it can be used with any other language. English in this document, but it can be used for any other language.

1 Introduction Depression as a common mental health disorder has long been defined as a single disease with a set of diagnostic criteria. It often co-occurs with anxiety or other psychological and physical disorders, and has an impact on feelings and behaviour of the affected individuals [1]. According to the WHO report, there are 322 million people expected to suffer from depression, equal to 4.4% of the global population. Nearly half of the in-risk individuals live in the South-East Asia (27%) and Western Pacific region (27%) like China and India. In many countries depression is still under-diagnosed and left without any adequate treatment which can lead into a serious self-perception and at its worst, to suicide [2]. In addition, the social stigma surrounding depression prevents many affected individuals from seeking an appropriate professional assistance. As a result, they turn to less formal resources such as social media. With the development of Internet usage, people have s-tarted to share their experiences and challenges with mental health disorders through online forums, micro-blogs or tweets.

Their online activities inspired many researchers to introduce new forms of potential health care solutions and methods for early depression detection systems. They tried to achieve higher performance improvements using various Natural Language Processing (NLP) techniques and text classification approaches. Some studies use single set features, such as bag of words (BOW) [2, 3], N-grams [4], LIWC [5] or LDA [6, 7] to identify depression in their posts. Some other papers compare the performance of individual features with various machine learning classifiers [8–11]. Recent studies examine the power of single features and their combinations such as N-grams + LIWC [12] or BOW + LDA and TF-IDF + LDA [13] to improve the accuracy results. With almost 326 million active users and 90 million publicly distributed tweets to a wide audience, Twitter is one of the most popular social networking sites [13]. Many researchers have used Twitter data successfully as a source of insights into the epidemiology of users tweeting emotions, depression and other mental disorders. As an online discussion site conducted by multiple groups or “sub-reddits,” Reddit social media is widely used. It is also used for discussions on stigmatic subjects because it enables the users to be totally anonymous. The posts of Reddit users who wrote about mental health discourse were studied by Choudhury. Features such as self-concern, weak linguistic style, decreased social participation, and the expression of hopelessness or anxiety predicted this change.
2 Related Work To provide new insight into depression detection, there are different types of research exploring the relationship between mental wellbeing and language use. Sigmund Freud [12], dating back to the earliest years of psychology, wrote about Freudian slips or linguistic errors to expose the authors’ inner thoughts and feelings. Various approaches to the relationship between depression and its language have been established through the development of sociology and psycholinguistic theories. For example, according to the cognitive theory of depression of Aaron. Reference [12], affected people appear to view themselves and their environment in mostly negative terms. Via derogatory words and first-person pronouns, they also express themselves. Identify self-preoccupation as their typical feature, which can evolve into an intense stage of self-criticism. Other scholars have been inspired by these hypotheses to come up with empirical evidence for their validity. For instance, in three separate periods of their lives, Stirman and Pennebaker [12] compared the word use of 300 poems written by 9 suicidal and 9 non-suicidal authors. The findings indicate that more first-person singular pronouns (I, me or we) were used by suicidal poets. Depressed students used more negative words and fewer positive words of feeling, according to his findings. In order to predict the improvement of depressive symptoms, Zinken et al. [13] investigated the psychological importance of syntactic structures. He assumed that in its word use, a written text may barely differ; however, it could differ in its syntactic structure, especially in the construction of relationships between events. Analyzing the roles of cause and insight. Studies on depression and other mental health problems have brought new challenges with the advent of social media and the

Internet era. In order to capture user behavioural patterns, online domains such as Facebook, Twitter or Reddit have provided a new forum for groundbreaking analysis with a rich source of text data and social metadata. As an online discussion site conducted by various groups or “subreddits,” Reddit social media is widely used. Since it allows the complete privacy of users, it is also used to address stigmatic subjects. Choudhury et al. [13] reviewed the posts of Reddit users who wrote about the debate on mental health and later moved to fix suicidal ideation problems. In the recent past, in a large research community, shared tasks potentially applicable to different circumstances have become significantly common. RISK, or the Early Risk Prediction Conference and Labs Assessment Forum, is a public competition that enables researchers from various disciplines to participate and collaborate on the production of reusable benchmarks for the assessment of early risk detection technologies used in various fields, such as health and safety.
3 Problem Statement Patients of mental problems such as Alzheimer’s, depression, anxiety and neurodegenerative diseases. The most depressed place in the world is India. Using Natural, after taking input as text data, results will be extracted from the dataset. Language processing algorithm and classification algorithm algorithm to find the data as depression data and prediction or not as a suicidal post.
4 Proposed System Data Pre-Processing: We will take our first look at it now that we have received our data, looking for missing values and selecting which sections of the data set will be useful for our classifier. We’re also going to start pre-processing text information with natural language tools. Some exploratory data analysis and visualizations end with this portion. Before we move to the feature selection and training level, we use the NLP tools to pre-process the dataset. To divide the posts into individual tokens, we use tokenization first. Next, we remove all URLs, punctuations, and stop words that might lead to erroneous results if ignored. Then, we apply stemming to reduce the words to their root form and group related words together (Fig. 1). Extracting functionality: After data pre-processing, we feed our models with the characteristics which reflect the language habits of users in Reddit forums. To explore the linguistic use of the users in the blogs, we use the LIWC dictionary, LDA topics, and N-gram features. To encode words to be used by different classifiers, these methods of text encoding are used. N-gram modelling is used to analyse the characteristics of the documents. In text mining and NLP, it is widely used to calculate the probability of co-occurrence of each input sentence as a unigram and bigram as a function for depression detection [8], [40]. As a numerical statistic for n-gram modelling, we use the Term Frequency-Inverse Document Frequency (TF-IDF), where the value of a word is highlighted with respect to each corporate document (Fig. 2).

5 Proposed Methodology Architecture In computational linguistics, topic modelling is an important method to reduce the input of textual data feature space to a fixed number of topics [19]. Hidden topics such as subjects connected with anxiety and depression can be extracted from the selected documents via the unsupervised text mining approach. It is not generated by a predetermined
176
A. Mali and R. R. Sedamkar
collection of pre-established terms in contrast to LIWC. However, it produces a category of non-labelled terms automatically (Fig. 3).
Fig. 3 Block diagram of proposed system
We use classifying methods to quantify the probability of depression among the users in order to quantify the presence of depression. Using Logistic Regression, Support Vector Machine, Random Forest, Adaptive Boosting and Multilayer Perceptron classifier, the proposed structure is built (Fig. 4).

Adaptive Boosting (AdaBoost) is an ensemble technique that can make one strong classifier combine several weak classifiers [56]. It is commonly used for problems of binary classification, A special case of the artificial neural network, Multilayer Perceptron ( MLP) is mostly used for modelling complex relationships between the input and output layers [58]. It is able to discern data that is not only non-linearly separable due to its many layers and non-linear activation [59]. In our analysis, we used the MLP method and two hidden layers with 4 and 16 perceptrons to correct all the characteristics in order to ensure accuracy of the comparison (Fig. 5).
Fig. 5 Flow of proposed system
Since depression also affects psychomotor functions [60], we can find terms that represent the symptoms of low energy, exhaustion or inverse insomnia and hyperactivity (tired, I ’m tired or sleepy). It is also articulated somatically (my brain, discomfort, hurt) via the symptoms of the body. Unigrams and bigrams in regular posts, unlike depressionindicative posts, contain the terms identifying the events that happened quite in the past (time, month ago, year ago, last year) (Fig. 6). To evaluate the connexion between the textual data and the features themselves, we selected 68 out of 95 characteristics. In view of psycholinguistic characteristics resulting in association provided in the features extraction, we transformed every depressive and non-depressive post into numerical values. The Psychological Mechanisms (0.19) followed by the Linguistic Aspects (0.17) and Personal Concerns (0.16) show the greatest correlation. c)GSM Module Working (Fig. 7).

The findings indicate that depressed individuals use more self-oriented references with respect to the mental concentration of depressed and non-depressed users and prefer to shift their attention to themselves (I, me, and mine) (0.17). The work of [12, 13] is confirmed by the findings. With a stronger focus on the present and future, their posts contain more negative feelings, depression and anxiety. Based on our results, when applied to the design tools, LIWC may play an effective role in data detection models (Fig. 8). We developed a topic model to quantify the hidden topics extracted from the posts, which acts as a depression triggering point. LDA requires that the number of topics produced be specified. Any parameter change can trigger a change in the accuracy of the classification. For this purpose, an acceptable value needs to be identified.

6 Results Deployment done using flask where as in user right in text box it will call the backend API and through that will give the result as shown in Fig. 9. There is an 90% accuracy of prediction depression text data. The data was extracted from Reddit and categorised by subreddit, with VADER Sentiment analysis performed on each request. Separately from the test set, a training set of data was developed. The training set of data was pruned to exclude submissions that were overly positive for r/SuicideWatch and excessively negative for r/CasualConversation. This was achieved to increase the training data’s divergence. The data was fitted and transformed using a Spark Machine Learning Pipeline that generated features based on TF-IDF analysis and the negative sentiment.

Abstract. Online News Portals are currently one of the primary sources used by people, though its credibility is under serious question. Because the problem associated with this is Click-bait. Click-baiting being the growing phenomenon on internet has the potential to intentionally mislead and attract online viewership thereby earning considerable revenue for the agencies providing such false information. There is need for accurately detecting such events on online-platforms before the user becomes a victim. The solution incorporates a Novel Neural Network Approach based on FastText Word2Vec Embeddings provided by Facebook and Natural Language Processing where Headlines are specifically taken into consideration. The proposed system consists of Hybrid Bi- Directional LSTMCNN model and MLP model. Promising Results have been achieved when tested on a dataset of 32,000 columns equally distributed as Click-bait and Non-Clickbait, in terms of Accuracy, Precision and Recall. The graphs achieved are also self-explanatory in terms of reliability of the system. A comparative analysis is also been done to show the effectiveness of our design with respect to detecting Click-bait which is heavily present on-line.

1 Introduction Currently, print media is replaced by digital media, resulting in the increasing number of news portals that provides a number of information. The growth of online media led to Click-bait, which is a negative impact of online journalism referring to the consumption of unrestricted or appalling headlines with only intention of attracting traffic and mouse clicks to gain more and more revenue from site. Often written in a language which is misleading and has provocative sentences. A title gives the first impression and dominates the user’s approach and is a key term in the news. As theory stated by Lowenstein states that Click-bait is the result of lack of understanding created by one’s interest in certain matters. This gap is capable of affecting one’s emotions. In the time of instant access to internet, people are increasingly consuming more and more contents in the name of news, images and videos for e.g., YouTube or from internet rather than trusted cable networks and news agencies (Fig. 1). © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2022 V.

Fig. 1 Overview of click-bait
The time spent by people on online media is anticipated to be much more than people spend on traditional TV worldwide in the year 2019. Considering, YouTube has more than a billion users occupying nearly one-third of the Internet population and reaches billions of views per day. An online news typically is made up of title, thumbnail, and the video content. Before the news the title and thumbnail (in case of video) are visible to the viewers, before they click and actually identify the content. Hence, headlines are found to be the crucial factors that attracts the users to click and watch any video. The content is clearly different from its title or thumbnail. The content is specially generated to attract viewers to click video and increase the viewership of the video. However, spreading of Click-bait videos wastes the time of viewers also decreases the trustworthiness towards journalism. Listed below are few examples of Click-bait headlines: • You won’t believe…… • These 12 tricks ……will change your life…… • Omg!!! Click to see what happens next…. Using intentionally deceiving links, tweets, or social media posts to attract online viewership, are all strategies of Click-baiting and it has been one method of flooding misinformation on the internet. A lot of attention has come towards Click-bait even though research in the field of Click-bait detection is still in an early phase. Because of its extensive use in online media and news, significant fallout has started to happen against social media platforms where any such content is found. Social Media platforms such as Facebook decided to take action against such activities, however it still continues to be flooded with such articles. To fight against this, huge number of Twitter handles have emerged and gained number of followings, with only purpose to identify Click-bait. Handles such as @SavedYouAClick and @HuffPoSpoilers are consistently updating their feeds with such posts to create awareness about them. The method is bit time taking because of their manual detection as users running those accounts themselves read and classify the tweet as Click-bait or not for the benefit of people. According to sources sentimental headlines create more curiosity among people and leads to Click-bait. Around 69, 000 headlines from four international media houses in 2014 were analyzed based on polarity of sentiments and found extremities in sentiments resulted in increased popularity. Headlines are the first impression and it can affect how the news articles are considered by users. A headline strongly affects which existing knowledge is triggered in one’s brain. By its way of phrasing, a headline can dominate one’s mindset so that readers later recall details that coincide with what they were expecting, leading individuals to perceive the same content differently according to the headline. Another explanation is the frequently said Loewenstein’s information gap theory. In simple words, the theory states that whenever we distinguish a gap between what we
184
A. Khan and M. Patil
already know and what is unknown to us, that gap has emotional consequences. Such information gaps lead us towards false content provided online (Fig. 2).
Fig. 2 Effect of click-bait on mental state
2 Literature Survey The Click-bait detection system proposed here has been primarily built upon feature extraction. Where in total 60 features are taken into consideration [1]. The baseline experimental setup constitutes: (a) (b) (c) (d)
Logistic Regression, Support Vector Machine Convolutional Neural Network Parallel Convolutional Highway Network
In the following model word embeddings learned from a large corpus is used. The corpus consists of the data collected from Reddit, Facebook, Twitter, and keeping the hyperparameters constant, the word embeddings are then fed to convolutional neural network [2]. The model here achieves higher accuracy without any feature extraction or hyperparameter tuning. A simple CNN with one layer of convolution is used here. The following paper demonstrate the approach based on machine learning for detecting Thai Click-bait. Such texts mostly consist of attractive words, low quality of information regarding the content to gain visitor attention. The corpus is generated by crowdsourcing, 30,000 of headlines to draw up the dataset [3]. The work specifically shows how to develop Click-bait detection model using two type of features in the embedding layer and three different networks in the hidden layer. Click-bait spread wider and wider, with the evolution of online advertisements. It disappoints the users because the article content does not go along with their expectation. Thus, recently detecting Click-bait has quite a lot of attention. Limited information being the reason in headlines [4] traditional Click-bait detection methods are built upon heavy feature engineering and cannot appropriately distinguish Click-bait from normal headlines. A suitable network can be Convolutional Network and can be useful for its detection, since it uses pretrained Word2Vec embeddings to understand the semantics of headline, and uses different kernels to find various characteristic feature of the headlines.

185
However, different ways to gain users attention are used by different articles, and cannot be distinguished by pre-trained Word2Vec easily. To address these issues, a Clickbait convolutional neural network (CBCNN) is built to consider not only the specific characteristics but also overall characteristics features from different types of article. The results show that the method currently outperforms all the traditional methods and the Text-CNN model in terms of precision, recall and accuracy. The use of misleading techniques in user-generated news portals are ubiquitous. Unscrupulous uploaders intentionally mislabel video descriptions aims to increase their views and results in increasing their ad revenue [5].
3 Problem Statement The work stated in this paper solves the following issues: • To identify Click-bait and non-Click-bait headline and classify them successfully. • To obtain word embeddings for the words present in the dataset and specifically, for rare words, which was found to be the common drawback in almost all proposed solutions till now. • To allow the system to run on CPU rather than GPU. Thus, it is considered to be a binary classification problem, where the headline is taken into consideration.
4 Data Collection and Visualization The data is collected from Kaggle. The spam headlines are collected from sites such as ‘BuzzFeed’, ‘Upworthy’, ‘Viral Nova’, ‘That scoop’, ‘Scoop whoop’ and ‘Viral Stories’. The relevant or non-spam headlines are collected from many trustworthy news sites such as ‘Wiki News’, ‘New York Times’, ‘The Guardian’, and ‘The Hindu’. The dataset in total has 32,002 rows and 2 columns. It has two columns. The first column consists of headlines and the second one has numerical labels or binary labels of Click-bait in which 1 represents Click-bait and 0 represents non-Click-bait headline. The dataset contains total 32,000 rows of which 50% are clickbait and other 50% are non-clickbait, shows that dataset is equally distributed (Table 1).

An additional variable “document length” is used here which accounts for total words present in a headline, in order to understand the distribution of headlines in training and testing datasets (Fig. 3).
Fig. 3 Word cloud for click-bait and non-click-bait headlines respectively
The above visualization of Click-bait and non-clickbait datasets clearly shows the dissimilarities between these two. The following Fig. 4 shows the top words and their count.
5 Proposed System The development of the proposed system has been classified into phases for ease of operations. The first phase is built by pre-processing of textual data using Natural Language Processing technique. In this, extra white spaces, punctuations have been removed. Entire headline is converted from uppercase to lowercase. Stop Words Removal and tokenization have been done. While performing visualization on the dataset it has observed that numbers also play an important role in Click-bait headlines, hence numbers are kept for detailed analysis of headlines. On the other hand, stemming and lemmatization chop off the entire word in one way or other, so there will be nothing in specific to feed to a neural network, hence both these techniques are not used in here (Fig. 5). In the next i.e. Second phase FastText word embeddings are obtained for the dataset that will be fed to the neural network. FastText: It allows users to understand and use text representations and text classifiers as it is an open-source, free, lightweight library. Standard, generic hardware is needed for working with FastText. Models in later stage can be reduced in size and can be made able to be used on mobile devices. It is another word embedding method and an extension of the word2vec model. Instead of learning word vectors directly, FastText represents each word as an n-gram of characters. This helps in capturing the meaning of shorter words and allowing the embeddings to understand suffixes and prefixes. It works on

CPU rather than GPU. This makes our model really effective in terms of cost. Here, for this model FastText embeddings provided by Facebook for text classification is used, which is 2-million-word vectors generated from common crawl in total accounts for 600 B tokens. The next and the third phase is model building with the embeddings generated.

The loss function used here is binary cross entropy and Adam optimizer is used along with “sigmoid” activation function. Multi-layer Perceptron Model: In machine learning MLP algorithm is known to be the backbone of deep learning. Using MLP with proper parameters and FastText word embeddings, it can give considerable result (Fig. 7).

7 Conclusion To stop and demote the excessive usage of click-bait headlines by agencies in order to earn revenue for themselves and flooding the online portals with fake news, novel neural network architectures are been proposed, and it has been found out that word embeddings play a major role in increasing the accuracy and reliability of the system. Also, the Bi-Directional LSTM-CNN model performs better than MLP model with FastText word embeddings and outperforms all other classification algorithms and Word2Vec techniques by achieving highest accuracy till now.

Abstract. A Wireless ad hoc network (WANET) is a decentralized brand where all nodes compete in routing by promoting data for supplementary nodes. This is arranged in a disaster region to gather patient’s data and develop medical amenities. The health information gathered from these calamity regions are compressed and transmitted through this network for treatment purposes. During this process several issues identified comprises of the quality of service (QoS) issues, interference between nodes, connectivity issues, efficient routing, security or authority issues, scalability, network topology, network lifetime, battery power consumption, network bandwidth etc. To overcome these issues so far many algorithms for instance data compression (DC) algorithms, routing algorithms etc. Furthermore several issues exist with these existing algorithms. This work reviews some existing algorithm their advantages and limitations identified with the existing works in DC and transmissions and also provide future study and growth directions.

1 Introduction The WANETs is self-assured of numerous tiny nodes sprinkled in the calamity region. The nodes are adequate of wirelessly transferring the composed health data to the base stations [1]. A WANET is meant to be arranged in a calamity region to gather data of patients and look up health facilities [2]. In the calamity region model, a calamity circumstances is alienated into diverse context-based regions (illustrated in Fig. 1) such as the calamity region, casualty treatment region and transport zone [3]. The ad hoc network (NET) architecture is applied in trade, corporate companies to enhance the yield and revenue. The NET is divided according to their appliance as Mobile Ad hoc NETwork (MANET) which is a identity managing infrastructure less network, Vehicular Ad hoc NETwork (VANET) that utilizes driving cars as network nodes [4]. Rather than these applications it can be also applied in other purpose for instance military arena, provincial level, industry sector, Bluetooth etc. [5]. DC is the procedure of transforming a source data stream to a new data stream i.e. the compressed stream that © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2022 V. E.

has fewer bits [6]. Several common issues identified in NET comprises of restricted wireless choice, secret terminals, packet fatalities, route changes, heterogeneity in devices, power constraint in battery etc. [7]. Further the key concern includes energy conservation, unstructured network topology, scalability, low quality communications, resource constrained computation, hidden node crisis etc. [8]. Finally NET has no centralized authority, QoS, sufficient admission control and interference between the nodes [9]. In wireless networks, all node has undeviating radio association to further nodes, known as its peers. Before efficient routing the nodes determine and recognize the network interface addresses (NIAs) of their neighbours labelled peer discovery. The crisis is essential in NET [10]. So far several techniques are proposed to resolve these issues that comprises of a dual authentication method to offer a high stage of security and prevent unauthorized vehicles incoming into the VANET [11]. Then a vibrant trust prediction model rooted in the historical behaviors of nodes is presented. This is then integrated with a Source Routing method named as Trust-based Source Routing protocol (TSR) [12]. Then a neighbour coverage rooted probabilistic rebroadcast protocol is proposed for dropping routing overhead in NETs [13]. A procedure for signal potency depending on tie availability calculation is utilized in Ad-hoc on demand Distance Vector (AODV) routing. At this point the nodes calculate approximately the link crack instance and hint the other nodes concerning the link discontinuities [14]. A directional routing and scheduling scheme (DRSS) is presented that enhance the energy effectiveness in consideration of congestion, safeguard and interruption [15]. Apart from this WANET suffer from DOS attacks comprising black hole attack (BHA), grayhole attack, wormhole attack, byzantine attack etc. [16]. To overcome the security issues a hierarchical structure rooted in chance detection and usage control (UCON) skills is presented. The features of UCON tackle continuing attacks [17]. The paper structure is as pursues Sect. 2 facts the review on recent

2 Review on Recent Works for Lossless Compression A. Medical Data Compression in WANET Wagh et al. [18] described an application based on WANET which was deployed in calamity region. An AODV was used as routing protocol between the nodes. This AODV protocol was independent of any location information. Medical Data of Patient (MDP) was main entity of raw images of patients such as endoscopic image. These images are of large size and use up lot of bandwidth and also decline the life span of the Remote Medical Monitoring (RMM) system was introduced for routing the health data in the calamity region. The proposed structure comprised a apparatus that collected, compressed, and transmitted compressed health data to the base station via WANETs. Dutta [19] discussed about WANETs that is self-possessed of nodes sprinkled in calamity region. The nodes were capable to wirelessly broadcast the composed health data to the base stations. To tackle this concern, an optimization based health DC method, was proposed which was vigorous to broadcast faults. Then a fuzzy-logic-based direction choice procedure was given to distribute the compressed data that maximized WANETs lifetime. The technique does not employ several environmental data. Cho et al. [20] described about health information systems that were striving towards observing models to concern patients through Electrocardiogram (ECG) signals. Conversely, there were limits for instance data distortion and restricted bandwidth. Hence this study alerted on compression. Moreover this work presented an algorithm Encoded Data Lempel–Ziv–Welch (EDLZW) for ECG data transmission. B. Security Issues Nogueira et al. [21] described about raising reliance of citizens on crucial applications and wireless networks to assure protected and dependable service operation. To maintain network actions and security needs of serious applications, SAMNAR, a Survivable Ad hoc and Mesh Network Architecture was presented. It provides protective, reflex and liberal security means to necessary forces in attacks. SAMNAR was used to devise a trail selection method for WANET. Yao et al. [22] discussed safe routing in a multihop WANET in front of eavesdroppers. The eavesdropper’s positions were moulded as a consistent Poisson point process (PPP) and the source–destination duo was aided by middle relays by the decode-and-forward (DF) policy. To assist finding a key to secure routing, estimation of the SCP was derived. A Bellman-Ford algorithm was assumed to discover the best trail. Cai et al. [23] focused on relay transmission for safe letter of a private message in the existence of snoopers. The source–destination duo is capable of potentially aided by relays. For a random relay, precise terms of safe association likelihood for colluding and non-colluding eavesdroppers were derived. Additionally, minor bounce terms on

the safe association likelihood attained. These lower bound expressions, was used to proposed a relay assortment approach to progress the safe association likelihood. Xu et al. [24] depicted Physical Layer Security (PLS) in wireless communication systems. The amalgamation of PLS and QoS for route choice in multi-hop WANETs remains a technical issue. This work focused on a multi-hop WANET with two transmission plans like amplify-and-forward (AF) and decode-and-forward (DF), and discovers the route selection with the deliberation of both security and QoS. Kulkarni et al. [25] discussed the knowledge dispatch in active network is named Delay Tolerant Network (DTN). One main concern on this network is safety. This work is centered on the shield issues associated with DTN routing protocols. The routing in DTN is a concern, resulting in non-operation of routing protocols, non efficient network, and it’s believed to routing hard to safeguard beside attacks of hateful deeds, to nonexistence of central power in DTN. Kiskani and Sadjadpour [26] described about caching that intend to hoard data nearby in several nodes inside the network to be capable to recover the fillings. However, caching in the network did not believe secure storage. Here, a decentralized safe coded caching loom was projected. Here nodes just broadcast coded records to evade snooper’s wiretappings and defend the consumer fillings. Here arbitrary vectors were utilized to merge the fillings by XOR action. The proposed coded caching method was modeled by a Shannon cipher scheme to prove that coded caching attain asymptotic privacy. Hence by the proposed plan, any filling can be rescued by choosing an arbitrary lane. Xu et al. [27] studied the safe optimal QoS routing (SOQR) in WANETs rooted on the PLS techniques. First closed-form expression was derived of connection outage probability (COP) and secrecy outage probability (SOP) for any specified end-to-end (ETE) trail Then, the least COP habituated on that SOP was explored under a threshold and the equivalent realizable power allotment was attained. With the aid of study of a known trail, additional SOQR algorithm was proposed which choose the safe trail amid source and destination nodes duo. Zhang et al. [28] addressed the issue of recognizing and dividing mischievous nodes that reject to send packets in multi-hop NET. An Audit-rooted Misbehavior Detection (AMD) was urbanized that isolated nonstop and choosy packet droppers. The AMD integrated honest route innovation, reputation management, and misbehaving nodes discovery rooted on behavioural checks. AMD also notice choosy dropping attacks when ETE traffic was encrypted and is practical to multi-channel networks. C. Algorithm for Detecting Attacks in WANET Shu and Krunz [29] described about connection fault and wicked packet dropping. In this work insider-attack, whereby malicious nodes (MN) use their information of the communication environment to fall serious to the network performance was explored. To advance the accuracy, the connection amid vanished packets was developed. Moreover, to guarantee honest computation of these associations, a homo-morphic linear authenticator (HLA) was developed rooted communal review structural design that permit the detector to confirm the honesty of the packet loss data. A packet-block-rooted method was moreover projected to diminish the calculation overhead.

Baadache and Belmehdi [30] described that in multi-hop WANET, nodes not in straight series rely on middle nodes to correspond. To protect its restricted assets, a middle node fall packets, in its place of forwarding it to descendant. In this work, this BHA was dealt, by proposing an authentic ETE response rooted method. Lee et al. [31] depicted the routing misbehavior of WANET where nodes were not forwarding letters properly. One time the attack was commencing, nodes in the network were not capable to dispatch letters. To spot the attack, previously a watchdog means was employed which is not competent with high false positive ratio. Here, a mechanism rooted on routing misconduct was proposed. It detected attacks and solved the issues in existing watchdog. Soleimani and Kahvand [32] since WANET have no central infrastructure and administration; they are susceptible to numerous safety threats. Hateful packet dropping is an attack in these networks, where an opponent node attempts to fall packets in its place of forwarding them to the next hop. In this work, an active trust representation was proposed to protect network beside this attack. Here, a node belief all instant neighbors originally. Attainment of feedback from neighbours’, a node revises the equivalent trust rate. Koh et al. [33] presented a phantom-receiver-rooted routing plan to improve all source–destination duo anonymity while employing a modifiable overhead. Also this included conventional network policy and opportunistic routing to drip appropriate confidentiality and to mitigate vulnerability. Also the destination was allowed to secretly surrender a response to the source. Chen et al. [34] described the characteristic of non-infrastructure hold in WANET that experience diverse attacks. Besides, user certification was the original protection fence in a network. A common faith was accomplished by a protocol that enabled corresponding gathering to verify everyone together and to swap session keys. Thus, a user verification plan rooted on the self-certified public key scheme and elliptic curves cryptography was proposed. Hence, a collaborative user verification and safe session key contract was attained. Sneha and Jose [35] described about packet loss which is an issue rooted by hateful packet dropping. It is hard to separate the packet failure owing to connection fault and hateful sinking. Here are mechanisms which spot the hateful packet sinking by relationship amid packets. An assessment planning rooted on homomorphic linear authenticator was employed to guarantee the response of packets confirmation. Also a repute method rooted on not direct reciprocity was employed to guarantee the forwarding of packets at each node. Shrivastava and Verma [36] portrayed the infrastructure-less characteristic of NET that has concerns like routing, security, MAC layer, etc. Security concern is a major one. Vampire attacks (VM) alter embattled packets by arranging extended way or misguiding the packets. MNs employ fake messaging affecting the bandwidth and node battery power. Routing and network possessions acquire VM defence; a method was proposed to discover hateful routing packets. The proposed method employed packet screening method to discover hateful packets.

D. Algorithm for Detecting Vampire Attacks Vasserman and Hopper [37] focused on security that payed attention on contact rejection at the routing. This paper explored supply exhaustion attacks at the routing protocol layer, which enduringly hinder networks by exhausting nodes’ battery power. These VA were not precise, but rely on the belongings of numerous routing protocols classes. It was identified that all inspect protocols were vulnerable to VMs, which are disgusting, hard to notice, and were easy to embrace away by as little as lone intolerable insider transferring merely protocol submissive letters. Umakanth and Damodhar [38] researched on ever more approved ideas from wireless communications. In this paper routing protocols, concern from attack yet those intended to be safe, require attacks guard, called VMs. An Energy Weighted Monitoring Algorithm (EWMA) method was projected to combine the crack rooted by vampire in the packet forwarding stage. Vijayanand and Muralidharan [39] discussed about ad hoc sensor wireless networks. The security work focused on contact rejection of routing admission manages levels. The attacks which were centered on routing protocol layer were recognized as resource exhaustion attacks. This attack causes the collision of continually stopping the networks by exhausting the node’s battery power. These VM were not impacting some exact protocols sort. Discovery of VMs was not a trouble-free one. A uncomplicated vampire in the network increased network extensive energy handling. Rajipriyadharshini et al. [40] described the energy wastage at sensor nodes. Wireless sensor networks (WSN) necessitate clarification for saving energy point. VM attack happen at network layer that guide to resource exhaustion at all sensor nodes; by destroying battery power. It broadcasts a little protest letters to stop an entire network, making it hard to identify and avoid. Existing protocols were not centred on this VM event on routing layer, then there subsist two attacks specifically, carosuel and stretch attack. New PLGP protocol, a precious and safe protocol was proposed with the key administration protocol entitled Elliptic Diffie-Hellman key swap protocol to evade VM. Vasserman and Hopper [37] depicted WSN in globe are the way of contact. These contain nodes that operate as transmitter and receivers were attacks prone leading to fatalities. The resource exhaustion attack VM ditches out the energy. These attacks were protocol acquiescent, they were effortless to apply. As they were orthogonal they know how to infringe into every routing protocol. They distress the whole network grounding energy failure. The proposed method notice the occurrence of VM shows the energy consumption [60]. Kwon et al. [41] studied safe contact by the joint loom of sport hypothesis and stochastic geometry, where legal transmitters and eavesdroppers are dispersed. Two scenarios were considered to the Eve level plan: (I) the Eve level activate nodes to maximally snoop the secret letters of the Alice level and (II) the Eve level triggers just few nodes to capitalize on its energy efficiency (EE) in snooping according to the Alice level node establishment. In situation I, an irregular optimization plan was proposed that take advantage of the secrecy EE of the Alice tier by calculating the node launch likelihood, the secret letter rate, the redundancy rate, and the count of dynamic antennas. In situation II, an EE node launch game was set among the Alice level and the Eve level,

where the earlier and the second manage their node-activation likelihood to exploit the confidentiality EE and the snooping EE. E. Security Issues in MANET Turkanovi´c et al. [42] discussed the distinguishing features of MANETs, with lively topology and unlock wireless standard, may guide to MANETs anguish from safety vulnerabilities. Here, a faith administration plan was proposed that enhanced the safety. Here the faith outline has two works: faith from straight and circuitous observation. With straight study, the faith value was copied by Bayesian inference. Conversely, with circuitous study, the faith value was copied via the Dempster-Shafer theory (DST). Movahedi et al. [43] depicted that trust management to conduct node’ transactions and set up management interactions in MANETs. Need of central administration, strict resource limitation, and network dynamics make faith administration a risky mission. In this work, diverse faith administration frameworks geared for MANETs was offered, that hold active attacks misleading honesty calculation to misinform faith-rooted network actions. Moreover, a holistic classification was proposed. For all structure, a loom was employed to explain the faith form, enchanting all components for faith administration as a instruction. Dhananjayan and Subbiah [44] depicted safe data transport alongside the hateful attacks in MANET. The requirements of nodes positional data revise in AODV protocol recommend less faith level between the nodes. A trust-aware ad-hoc routing (T2AR) protocol was given to advance the faith level among the nodes. This mode modified the usual AODV routing protocol by limitations of faith rate, energy, mobility rooted hateful deeds forecast. The packet series ID identical from the record information of neighbor nodes conclude the faith rate avoiding the hateful details creation. Muthuramalingam and Suba Nachiar [45] described faith rooted models that present security. Here, two schemes like, straight and circuitous examination rooted faith assessment were proposed. Originally, the network was created to examine security. The full likelihood form exploitation in Bayesian edge evaluated the faith from the spectator node in straight surveillance system. On the other hand, the neighbour hop data was employed in the origin of faith value in circuitous examination plan. The Dempster-Shafter hypothesis calculated the faith rate following the examination plans. After all, the Dijkstra’s algorithm launches the routing procedure rooted on shortest trail. Ahmed et al. [46] debated locked data distribution that is a tricky job in MANET. This work proposed Flooding Factor rooted Framework for Faith Administration (F3TM). True flooding loom was exploited to recognize attacker nodes rooted on the computation of faith value. Route invention Algorithm was urbanized to determine a data trail for sending by investigational Grey Wolf algorithm for authenticating network nodes. Improved Multi-Swarm Optimization was employed to optimize the release trail. Ullah et al. [47] figured faith advice, encompassing a critical part in calculation of faith and confidence in peer to peer (P2P) atmosphere. So, alleviation of dishonest faith suggestion was predetermined as a challenging concern in P2P systems (esp in MANET). To gratify these concerns, “intelligently Selection of Faith Recommendations rooted on
Data Compression and Transmission Techniques in Wireless
201
Dissimilarity factor (iSTRD)” was devised. iSTRD develops individual knowledge of an “evaluating node” in combination with common vote of the recommenders. Wei et al. [48] proposed a trust administration plan that enhanced Manet’s security. The proposed faith administration scheme has two mechanisms: faith from straight and circuitous test. With straight test from a spectator node, the faith value is imitative by Bayesian inference. Alternatively, with circuitous inspection, the faith value is derived by the DST. Singh et al. [49] debated the routing protocol design with EE and security. To conquer this dispute, EE secured routing protocol was proposed. To offer safety for association and letter without relying on the mediator, security was provided by a safe association for routing by safe Optimized association State Routing Protocol. All nodes decide multipoint conveys nodes amid the one-hop neighbours set, so as to attain all two-hop neighbors. The admission rule unit approve nodes proclaiming the node discovery. After selecting the association, on need of a fresh way, ensure nodes’ power position in its routing table and then consequently start a way. Then, execute set key allocation using the produced keys. The group key can be distorted occasionally to evade non-authorized nodes. Then, offer letter privacy for message correspondent and message receiver. Poongodi and Karthikeyan [50] depicted BHA which confine the way from starting place to target by transferring respond with main sequence digit and smallest hop count. Here, Localized Secure Architecture for MANET (LSAM) routing protocol was projected to discover and avoid supportive BHA. Security Monitoring Nodes (SMNs) would be triggered only if the threshold rate was surpassed. If MNs were identified, former SMNs in its immediacy spot are humiliated to detach the MNs. Kaliappan and Paramasivan [51] discussed the challenges of MANETs to different security attacks. Because of central management lack, safe routing was tricky in MANETs. Sport theory was employed as a means to analyze, formulate and crack egoism concerns in MANETs. This work used a Dynamic Bayesian Signalling sport to analyze tactic outline for usual MNs. The Payoff to nodes for motivating the exacting nodes concerned in misbehavior was calculated. Regular nodes observe endlessly to assess their neighbors by belief evaluation and faith revise method of the Bayes rule. F. Security Issues in Adhoc Networks Tan et al. [52] discussed that NET endure from diverse attacks in the data plane. To lock the data plane of NET, a faith administration system was proposed. Fuzzy logic (FL) was engaged that invent vague experimental data, and then estimate the path faith value. FL with graph hypothesis was approved to construct a faith form for computing the node faith rate. To protect attacks to faith administration systems, a filtering algorithm was proposed. An honesty decompose way was also intended to resolution the argument regarding the decomposing past faith rate in a faith-rooted routing assessment. As well, a faith factor collection approach was proposed to guarantee that the faith administration method was attuned with further security primitives. Finally, the proposed faith administration method was incorporated into the optimized connection state routing protocol.

Xu et al. [53] expresses PLS in NETs. To concentrate on these concerns, this work discovers the PLS alert routing and recital tradeoffs in a multi-hop NET. For one ETE path foremost, get its connection outage probability (COP) and secrecy outage probability (SOP) in closed-form, which provide presentation metrics of letter QoS and broadcast safety. Rooted on the closed-form terms, the security-QoS tradeoffs to diminish COP trained on that SOP was assured. Adams and Bhargava [54] focused on friendly jamming PLS method that uses further obtainable nodes to jam any snoopers. This work judges extra obtainable nodes employment as gracious jammers to advance the route security. This work considered routing issues during a D2D network as equally diminishing the SOP and COP, by gracious jamming to advance the SOP of all link. The jamming authorities were resolute to put nulls at gracious receivers whereas exploiting the snoopers’ power. Then the crisis was mounted as a convex optimization problem and an supplementary variable was measured to adjust the optimization among the two metrics. G. Security Issues in VANET Faghihniya et al. [55] conferred security in VANET acts critical task. The broadcast packets usage in the AODV route detection phase root it is tremendously susceptible beside DOS and DOS flooding attacks. The method proposed here is Balanced AODV (B-AODV) since it suppose all network nodes act usually. If network nodes were away of regular activities then they acknowledged as MN. B-AODV was intended with subsequent characteristic: (1) The exploit of adaptive threshold depending to network circumstances and nodes behavior (2) No additional routing packets was used to verify MNs (3) execute discovery and avoidance process autonomously (4) execute discovery and avoidance action in real time (5) No requirement for promiscuous mode. This technique for discovery and avoidance flooding attack utilize average and standard deviation. Krundyshev et al. [56] discussed information security problems in VANET. This examined routing attacks on dynamic networks, in which a MN supply fake routing data by promoting itself comprising shortest trail to the source node and then deny the traffic from the source node. A method to offer for VANET security by swarm algorithms of artificial intelligence was proposed. Li and Song [57] discussed the security and privacy challenges posed by VANETs. The honesty of VANETs was improved by tackling both data faith, and node faith. Here, an attack-resistant trust scheme (ART) was projected that notice and handle with cruel attacks and as well assess the honesty of data and MNs in VANETs. Data faith was assessed by the data sensed and gathers from numerous vehicles; node faith was measured in two proportions. Mokdad et al. [58] discussed VANETs that are considered as NETs with changed topology, making complicated resource administration and unlock a few strands in security. Particularly on the Physical and MAC layers that were extra susceptible. Thus, it is exigent to discern when broadcast data were not distributed to the target, if this is owed to an attack. In this work, an algorithm DJAVAN (Detecting Jamming Attacks in VANET) was proposed to identify a jamming attack.

He et al. [59] guaranteed secure communication in VANETs must be dealt. The conditional privacy-preserving authentication (CPPA) plan was appropriate for resolving safety and privacy-preserving issues, since it tackles joint verification and privacy guard. To attain improved presentation and decrease computational difficulty, the CPPA scheme design without bilinear paring for the VANET environment develop into a dispute. To tackle this, a CPPA plan was proposed for VANETs without bilinear paring (Table 1). Table 1 Description of existing medical data compression Technique

1 Introduction VANETs have appeal to the consideration of numerous researchers, for the capability of giving diverse use, for instance vehicle security associated services, Zhou et al. [1] VANETs are particular sort of short-extend wireless communications Mobile Ad hoc Network (MANETs). The vehicles in VANETs act as a node, connecting to one other to shape a network. Each contributing vehicle has program skills. Oubbati et al. [2] Numerous vehicle producers have outfitted their vehicles with Global Positioning systems (GPSs) and wireless contact plans [3]. The measure of vehicles has exponentially increased wherever on the planet, causing genuine traffic congestion. The congestion may result in an increase in street accidents and reaction times of emergency vehicles. Typically, emergency vehicles use alarms and lights to caution street clients about their presence and appearance. People on foot and vehicle drivers may wrongly decipher the appearance direction of the emergency vehicle because of some echo signals, in this way moving into its way and exacerbating © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2022 V.

the traffic circumstance. In any action, when they correctly decipher the way of the emergency vehicle, they might be in substantial traffic congestion or holding up at an intersection and thusly not in a situation to offer approach to them [4]. Traffic accidents and jams are triggering passing’s and misuse of fuel and productive hours [1]. These statistics could be compact by spreading upcoming traffic data in a timely way utilizing robotized process in vehicular specially appointed networks (VANET) [5]. One of the most important objectives of VANETs is to give security applications to travelers. What’s more, VANETs give comfort applications to clients (e.g., mobile internet fields, and climate data) [3]. Vehicles as mobile hosts can connect with one new directly if and just if their Euclidean distance isn’t longer than the radio spread range. Each vehicle right now treated as a host as well as a switch. Using DSRC empowers a wide assortment of driver-helping applications such as Vehicle to Vehicle (V2V) and vehicle-to-side of the road (VRC) informing of traffic and accident data just as permitting timely and shrewd communication to improve street security and traffic Stream [6]. The key know-how’s for VANETs, called V2V communications, include the vehicles networking of and extra communicating procedures. Force manage is the way to keep up the superior networks link amid plans, which is utilized for VANETs. Be that as it may, dissimilar to the modern mobile impromptu networks, VANETs have a great deal of uniqueness, for instance distribution, arbitrary node versatility, time–space indecision broadcast, and hindrance [7] Directing in VANETs is an invigorating endeavor on account of rapid adaptability and dynamic organization geographies. Low circulation dormancy and high dispersion share are two key targets in the goal of steering structures in VANETs, where the dissemination idleness determines the time frame it takes to make an impression on the objective and the conveyance proportion is the proportion of the amount successfully passed on interchanges towards the full scale number of correspondences [8]. Recent Intelligent Transportation System (ITS) presentations able to be isolated into significant classes; to be specific, on-street travel safety applications and infotainment applications. Traffic well being appliance comprise traffic checking during joint informing, insinuating visually impaired curve street, forestalling conflict during mechanical electronic split scheme, on-street constant traffic rooted traffic light action and traffic light data in read method [9]. A fuzzy-rooted trust prediction method has to implement in the way development in vehicular impromptu networks. In the calculated style, each vehicle representations the trustworthiness of the immigrants select the transfer nodes that can be utilized for information transmission and the election of the fitting way for routing in vehicular specially appointed network condition [10]. A. Applications of Vanets VANETs are considered by a collection of capable functions and facilities. A few methodical reports built up via models figures and modern groupings gradient many applications that will in the end be sent later on. We will recognize three programs of submissions: well being associated, traffic-associated, and infotainment. These programs are designated as trails.

(1) Security Related Applications: The reduction in the amount of individuals harmed or executed scheduled the streets is unique of the primary inspirations for the advancement then the investigation of VANETs. This group holds every presentation that mean to advance street well being. These presentations are then proposed to advance the imageground of the driver contribution a heavy guide to it. The driver can accordingly predict and respond to construct the dynamic knowledge additional secure. For instance, it very well may be educated that an automobile takes damaged the ruby traffic beam or a person on foot is traversing the street. (2) Traffic-Related Applications: This group comprise appliance that utilization between vehicular interactions to split traffic data amid vehicles so as to augment the driver knowledge and streamline the passage stream. Diverse situation can be conceived for this category akin to the collaboration amid vehicles to assist the section of crisis vehicles. (3) Infotainment Applications: This group comprises all applications that furnish drivers with data, diversion and promotions in their excursion like convention data services, Internet right to use, and capture spilling and record distribution. As they are tied in with donating extravagance services to drivers, these appliances are not interruption delicate appliance and can endure postponement. Contact rooted management in vehicle networking and vehicles collaborate amongst themselves structure amicable lines to stay away from calamities.
2 Survey on Recent Works for Vehicular Adhoc Networks A. Review on Message Propagation VANETS Zhou et al. [1] VANETs embrace the periodical transmit to scatter notice letters. The transmit means carries the issue of how to locate the appropriate letter duration for the spread of the notice letter. To attempt the previously mentioned issue, Vanet work embraces the accompanying four stages to examine the occasion driven admonition message spread process and propose an appropriate communicationperiod for the Vehicle-toVehicle (V2V) network. From the outset, an investigative form was proposed to explore the occasion driven admonition letter proliferation method in an associated network, and along these lines guarantee it is hard to secure total nodes in the ZOR presence in a similar segment. Subsequently, a logical form was proposed to examine the occasion determined admonition letter proliferation procedure in an apportioned network, and afterward the likelihood of conveying notice letters to every node in the ZOR for diverse traffic circumstances is determined. Moreover, to diminish idleness grounded by multi-jump transmit, a direction-mindful transmit protocol was proposed for the parceled network according to the proposed logical forms. The occasion driven admonition message engendering process in VANETS was investigated. Zhou et al. [11] described to break down the notice message proliferation process and recommend appropriate communication duration for the V2V network, foremost intend investigative forms to contemplate the notice letter spread procedure in the associated

and apportioned network. At that point, in view of the proposed models, determines the rescue likelihood beneath diverse traffic situations. Vehicle thickness, speed and perilous time. Examine the admonition letter spread procedure in VANETS, which can be in the connected or parceled networks. The proposed form, have determined the rescue probability beneath diverse traffic circumstances. Vijayakumar et al. [12] proposed another CPAV validation arrangement for safe vehicular message in VANETs which is shaped throughout IoT. In CPAV verification plan, a Road Side Unit (RSU) can efficiently validate vehicles in a mysterious way by giving security associated letters to vehicles. This plan not just gives the unknown verification little record and mark proof price, yet in addition gives a well-organized qualified confidentiality, trail method to uncover the genuine personality of the hateful vehicle for improving VANET method efficiency. It also gives improved effectiveness regarding quick authentication on record and marks than the recently announced plan than the before described patterns. Sugumar et al. [13] built up a faith rooted verification plan for cluster-constructed VANETs. In view of this at that point, all vehicles is checked by a lot of verifiers, and the letters are carefully marked by the dispatcher and encrypted utilizing a public/private key circulated by a faith power and decrypted by the ending station. This confirms the character of dispatcher just as recipient in this way giving verification to the plan. Eckhoff and Sommer [14] introduced a form of a best in class attacker utilizing a multi aim trailing algorithm and pertained this form in wide processor replications utilizing recreated vehicle development and genuine traces. The examination bolsters our discoveries that, beneath sensible presumptions concerning a foe’s potential, restricted confidentiality is neither essential nor can it be attained devoid of concession traffic well being. Roca et al. [15] proposed a technique using the network state data (i.e., the nodes versatility examples and link quality) to overcome flimsy communication in the haze computing and SDN-rooted connected vehicle condition. At that point manufactured a campus network utilizing the SUMO test system and executed the mobile SDN condition by modifying the Wifi. Hassan et al. [16] introduced Multi-metric Geographic Distance Routing (MGEDIR) protocol for VANET. M-GEDIR depends on subsequent jump vehicle assortment from active sending district in view of various metrics. The security territory and hazardous region was resolved for ideal subsequent bounce vehicle assortment. The outage likelihood of wellbeing and hazardous vehicles was assessed to abstain from picking inaccessible vehicle. Upcoming point was evaluated for the entire hazardous vehicles to stay away from shaky vehicles. The utilization of weighting aspects has empowered M-GEDIR to pick ideal vehicle ensuing in elevated throughput. It moreover diminishes jump calculation devoid of distressing the nature of connectivity ensuing in minor start to finish hindrance. The precise routing choice of the proposed protocol diminishes the likelihood of link disappointment ensuing in minor pace of way detachment.

B. Features of VANET Liu et al. [17] Examined VANET, a sub-class of MANET and is increasingly well known in advancing street wellbeing and Smart City applications. In particular, the better information sending have been discussed and furthermore introduced another cooperation approach dependent on Mobile Social Networking (MSN) alongside the conventional cooperation approaches. Each cooperation approach holds its own features, criteria and drawbacks. Tomar and Prakash Sharma [18] had anticipated the vehicle location and speed through GPS and assessed the comparable with aid of GPS innovation. By in that case, the preeminent assessment of the vehicle boundaries is made throughout Kalman channel by joining of the two likelihood thickness capacity of the assessment and assessment vehicle data. Kumar et al. [19] discussed the vehicles are assembled with RHET partitioning region enclosed by hand-off node in RHETBP, transfer nodes are determined utilizing equation WT in all region for subsequent jump, and file recipe can be utilized to limit link delay. Consequently, the number of hand-off nodes is condensed, and superfluous letter was condensed, as well. So the street calamity letter can be speedily spread in diverse tracks beside diverse streets about the calamity node. RHETBP doesn’t utilize cyclic signals, and neither keeps up the posting of neighbors for discovery of street junctures, which severely diminish network transparency, diminish holding up delay and sending node ratio, and advance coverage rate. Shah et al. [20] described a RSU-rooted effective channel access pattern for VANETs below high traffic and portability clauses. It dynamically adjusts the contention window of each vehicle dependent on its cutoff time of takeoff from the scope of RSU. Goudarzi et al. [21] proposed to stay away from channel overcrowding and to attain exactness. Right now, constraints comprising traffic thickness, vehicle position and spot position are measured as data sources. To wrap the diverse clauses of traffic thickness, another model by performing fuzzy logic was employed to discover the thickness of traffic. Balico et al. [22] VANET has unsteady wireless channel superiority, which is influenced by a couple of elements (e.g., street development, street surroundings, vehicle category, and vehicle velocity). (i) A hub that gives a firm power flow that the engine sponsorships. Space vehicle transporters can guarantee the receiving wire estimations and supplementary correspondence gear, yet as well enclose tough registering power and capacity limit. (ii) The hub progress by a specific consistency: it simply has two-course advancement next to a basic solitary way. Zheng [23] dissected a multi-source information blend way to deal with identify fake crisis letters, in which every vehicle employs its on-board sensor data and got signal letters to see the traffic circumstance and figures its conviction on validity for crisis

letters. Likewise, the proposed loom gives improved strength next to intrigue assaults via planning an anomaly discovery system in which a bunching calculation is carried out to filter through the colluder whose lead veers off generally from others. Banani et al. [24] discussed the location and path of the transmitter, just as nearness (i.e., communications from vehicles that are possibly not going to ground a calamity). Evaluating with supplementary existing plan, the examination outcome illustrate that the proposed system can validate letters from close by vehicles with inferior between letter delay and condensed packet misfortune and in this manner gives elevated stage of consciousness of the close by vehicles. Ji et al. [25] described a clustering algorithm subject to the data of course masterminded by vehicular course schemes. Comprising course data into cluster means isn’t minor because of two concerns: (i) reliability is a possession of time somewhat than position; (ii) course different assortment might root elevated re-clustering overhead at way junctions. To deal with the principle concern, we propose a task to quantitatively estimate the covering time amid vehicles reliant upon course data, with which a cluster head assortment metric. Gurung and Chauhan [26] depicted the Reasonable AODV (B-AODV) on the grounds that it expects all organization hubs continue routinely. In the event that network hubs are strange direct (an unnecessary measure obviously demands) by then they recognized as vindictive hub. B-AODV is tended to with following highlights: (1) The usage of adaptable limit as per network clauses and hubs lead (balance record) (2) Not using extra directing bundles to recognize noxious hubs (3) Perform identification and expectation activities independently on each node (4) Perform recognition and evasion tasks constantly (5) No necessity for wanton mode. Medani et al. [27] had proposed “Equilibriums Table Vigorous Telecom” (OTRB) calculation. At this moment, to every hub speaks with its area, a ton of hubs is chosen to extend the time over the complete organization. The proposed time synchronization convention is throughout acclimated to self-assertive organization geography changes, high nodal speed while offering extraordinary exactness and power against nodal frustration and parcel incident. C. Vanets Confinement Strategies Hassan et al. [9] portrayed IVD rooted network careful steering (Ivd-Vehicle) for upgrading availability careful data dispersal. IVD scheming is robust and can efficiently deal with immediate GPS disappointment. Two localization methods; in particular, supportive localization and Geometry rooted Localization are created. Average deviation of constant IVDs of a sending way is determined. Dissemination of IVDs of a sending way is utilized for evaluating connectivity. Portion vehicle established succeeding bounce means of transportation selection is used. Shams et al. [28] discussed a whole IDS in VANET utilizing the combinations of changed unrestrained mode for information gathering and SVM for information examination to set up a mutual belief an incentive for each vehicle on the network as Trust Aware SVM Built IDS (TSIDS).

Zhang et al. [29] examined two cluster-rooted algorithms for target aphrend in VANETs in our past works. These algorithms give a dependable and stable stage for tracking a vehicle dependent on its visual features. Menuar et al. [30] analyzed an Effective and QoS upheld Multichannel Medium Access Control (EQM-MAC) rules for VANETs in a road domain. The EQM-MAC protocol uses the overhaul network funds for non-security communication spreads through the entire organization interim, and it energetically changes according to the traffic clauses. D. Vehicular Communications Credentials and Detection Latif et al. [31] described in writing, different information dispersal schemes are proposed. Be that as it may, a large portion under meager or thick traffic clauses. Additionally, these plans don’t successfully conquer the previously mentioned concerns at the same time. Another information spread VANETs protocol that scatters the tragedy letters in diverse situations beneath shifting traffic clauses. In thick traffic clauses, DDP4V utilizes the division of communication locale about a vehicle so as to choose the mainly fitting next sending vehicle (NFV). So, it partitions the communication area fragment to advance the letter to all neighbor vehicles, though it furthermore utilizes implied acknowledgments as assured letter rescue in meager traffic clauses. Another information scattering protocol, DDP4V, to conquer the tricky transmit gale, network parcel, sporadically connected network, and ideal NFVs assortment issues. The projected protocol exhibits the likelihood to give a data scattering in arranged VANET circumstances with fluctuating traffic clauses. It offers sensible presentation in three dissimilar appraisal circumstances: road circumstances and two metropolitan circumstances by means of and devoid of network parcel. Beneath thick traffic scenario, DDP4V lean towards the vehicle(s) within the perfect part about transmission locale to retransmit the data packet. It reduce the data packet delivery delay with creating traffic compactness in completely assessed VANET circumstances as vehicles within the perfect bit communicate the data packet with most concise holding up time. Cart wheel concept helps theDDP4V protocol in choosing the finest vehicle as NFV to hold on the scattering procedure and alleviate the transmit gale. Gong and Yu [32] discussed right now, content downloading plan with the aid of side of the road left cars. The left cars, which organize a virtual cluster, assume the job of RSUs, downloading the content from the supplier and send out it to the downloader. Cluster builds a plan to inform the downloader concerning how to get content lumps from which clusters dependent on the evaluated downloader trail. Nguyen et al. [33] described a novel pattern utilizing a story-carry-forward (SCF) system to challenge the network segment and transmit gale issues that are two significant challenges in VANETs. The proposed system embraces a SCF method to unravel transmit storm also network segment issues, while keeping up elevated neighbor data perfection. The imitation end demonstrate that the SCF system beats different plan at relieving broadcast storms, and has a elevated delivery ratio crosswise different traffic
214
G. Jeyaram and M. Madheswaran
compactness. This resources the SCF plan functions admirably in both thick and meager traffics. Auxiliary examination centered on declining expectancy commenced by the transmit concealment method and SCF means. Kolandaisamy et al. [34] described MVSA approaches keeps up the various phases for detecting DDoS attack in web. The Multivariant flow examination offers one of a kind result dependent on the V2V letter during RSU. The loom watches the traffic in diverse circumstances and time outlines and keeps up diverse principles as different traffic modules in different time pane. An efficient Multi variant Stream Analysis (MVSA) approaches to perceive also mitigates DDoS attacks have being implemented. The vehicle peruses the network trace and calculates time to live, a normal proportion of payload, and the frequency as all stream categories at dissimilar time pane. Four features are estimated in the strategies to create the standard deposit. The standard deposit is produced also the features are mined from the packet established from the client. By and by, the strategy computes the multivariate stream weight. The strategy was demonstrated competent in perceiving VANET DDoS attacks and in this way condensed the collision on the VANET condition. Kadadha et al. [35] described a multi-pioneer multi-supporter Stackelberg sport classical that rouses nodes to perform considerately, being MPRs, by growing their notoriety. Assembled notoriety augments are utilized to decide the arrangement of devotees that a MPR (pioneer) course for dependent on nodes’ notoriety. Furthermore, the offered protocol offer a comparative percentage of chosen MPRs and start to finish delay compared to the benchmarks.

Abstract. Clustering is a technique of segregating the data points into certain clusters in such a manner that the data points present in the cluster are more similar in nature to the other data points in that cluster as compared to the data points that are segregated in different groups. In layman words, the purpose is to form distinct groups of data points having alike characteristics and allot it into the groups. The clustering algorithms are advocated for the task of classifying the spatial datasets into a set of groups. Generally, this algorithm can be distributed into two sections—Hard Clustering where every data object either corresponds to a group or cluster entirely and the other is Soft Clustering wherein the odds of that data object to be in those clusters is assigned rather than placing every data object into a distinct cluster. This paper focuses on comparative study of different clustering algorithms that are applied in data mining. Keywords: Clustering · K-means · Hierarchical · DBSCAN · Silhouette coefficient index · Davies–Bouldin index · Calinski–Harabasz index
1 Introduction Clustering technique is primarily defined as segregation of the data objects into collection of related objects. Such collections are called a cluster that consists of points having similar nature amidst themselves and disparate nature as compared to other groups. Clustering algorithms is the most widely used type of unsupervised machine learning algorithm [1]. In this respect, we compare among different types of clusters and found it more appropriate to place the algorithms such as: K-means algorithm, Agglomerative hierarchical [2] clustering algorithm and the Density Based Spatial Clustering of Applications with Noise (DBSCAN) [3] algorithm, to be under dissertation. They are generally used to find out how subjects are similar on a variety of different variables. However the algorithms are not eager learners and rather directly learn from the training instances. The most frequently used process of gathering the points consists of the several steps mentioned—feature extraction and feature selection that helps to extricate and handpick the supreme demonstrative attributes from the initial data set; next step is clustering algorithm design—that design the clustering algorithm corresponding to the features of the challenge; the following step is result evaluation in which we appraise the algorithm result and estimate the legitimacy of algorithm; and the last step is the result explanation—it gives a concrete elucidation for the aforesaid result.

that the application to large spatial [3] datasets promotes such prerequisites for the clustering algorithms: marginal necessities of the domain knowledge so as to influence the input considerations, the unearthing of clusters with capricious shape and fine efficiency on the large datasets.
2 Related Work Chitra and Maheswari, This paper focuses on a keen study of different clustering algorithms in data mining. A brief overview of various clustering algorithms are analysed and draw a conclusion that how this algorithm plays a significant role in data analysis and data mining applications. Besides, it is majorly the task of a combination of a set of objects in such a manner that objects in the identical group are more related to each other than to those in other groups. They elucidated that the clustering algorithms can be classified into partition-based algorithms, Chitra and Maheswari [4] hierarchical based algorithms, density-based algorithms and grid-based algorithms. Cluster analysis can be exercised by finding similarities between data according to the characteristics found in them and integrating similar data objects into clusters. Clustering has an extensive and prosperous record in a range of scientific fields in the vein of image segmentation, information retrieval and web data mining. Peerzada Hamid Ahmad, Dr. Shilpa Dang With the ongoing elevation in the technology, cluster analysis plays a significant role in analyzing examining text mining techniques. It segregates the dataset into several various meaningful clusters to exhibit the dataset’s natural structure. During the course of study, they look over the four major clustering algorithms namely Simple K-mean, DBSCAN, HCA and MDBCA [5] and detailed study on the performance of these four clustering algorithms. The behaviour study of these four techniques are evaluated in depth and interpreted using a clustering tool called WEKA. The resultant are tested evaluated on different datasets namely Abalone, Bankdata, Router, SMS and Webtk dataset using WEKA interface and compute instances, attributes and the time taken to build the model. Also they have highlighted the advantages, disadvantages and applications of each clustering technique. Khandare, Anand & Alvi, In this paper, they explored few reports on the improved k-means algorithms, abstracted their shortcomings and further identified any scope for enhancement in future to make it more scalable and efficient for large data. Conventional algorithms used in various fields of engineering science and technologies are the clustering algorithms. We also observed that the k-means is an exemplar of unsupervised clustering algorithm which is often implemented in applications in terms of medical images clustering, gene data clustering etc. In spite of extensive research work on the basic k-means clustering algorithm, the researchers could focused only on certain limitations of k-means. From the literature, it was observed that this paper studied distance, validity and stability measures, algorithms for initial centroids selection and algorithms to decide the value of k. Further, the author proposed the objectives and guidelines for enhanced scalable clustering algorithms. There were variour suggesting methods to avoid outliers using concepts of semantic analysis and AI [1]. Na, Xumin and Yong, Clustering analysis method is one of the main analytical [6] methods in data mining and this will have direct influence on the clustering results. This

paper deliberates the standard k-means clustering algorithm and peruse the limitations of standard k-means algorithms. To say, the k-means clustering algorithm is used to compute the distance between each data object and all cluster centers in each iteration, this in turn makes the efficiency of clustering on a lower side. So this paper put forward an improved k-means algorithm in order to resolve such challenges which have a simple data structure to store certain information in every iteration that might be used in the next iteration. The improvised method focused on evading to compute the distance of each data object to the cluster centers repeatedly, hence helps in saving the running time. The study predicts that this methodology can effectively improve the speed of clustering with better accuracy while reducing the computational complexity of the k-means. Valarmathy and Krishnaveni, Data mining in the educational system has received great interest and has become a new emerging research nowadays. Recently all universities and colleges [7] are generating huge volumes of data by conducting online exams and storing a lot of information for future purposes. These colossal amounts of data need some data mining techniques to retrieve some useful and meaningful information from the dataset. The real victory can be achieved only when a task specialized is applied so that it can be effective in that area. This paper surveys the purpose of data mining to the outmoded educational systems, various well known clustering algorithms, its applications, advantages and disadvantages. This paper also focuses on performance evaluation of some clustering algorithms using educational dataset.

3.3 Clustering Cluster mixing techniques are one of the utmost unsupported methods of ML. These approaches are applied to determine similarities and patterns of relationships between data points [11] and then combine those points into groups that are similar in terms of symbols. Merging is imperative as it establishes the internal collection between current data without labels. They make some assumptions about data points to make their similarities. Each assumption will create different but equally acceptable collections. Since the task of assembling is low, there are sundry ways to achieve this. The whole process follows a set of different rules to define ‘similarities’ between data points [11]. In fact, there are more than 100 known algorithms for integration. But there are a small number of widely used algorithms: • Connectivity models: As the name suggests, these models are centered on the notion that data points [11] closer to the data space show more resemblance to each other than data points lying far away. These species can follow two paths. In the first method, they first divide the data into isolated groups and then combine as the gap decreases. In the second method, all data points [11] are divided into a single group and then separated as the distance upsurges. Also, the choice of a distance job is logical. These types are very easy to translate but do not have the ability to manage large databases. Examples of these models are hierarchical clustering algorithms and their variations. • Centroid models: These are iterative integration algorithms where the concept of similarity is established on the proximity of a data point to the centroid collections. Kmeans compilation algorithm is a widespread algorithm that comes under this category. In these species, the number of [7] the required sets at the end must be listed down in advance, which makes it important to have prior knowledge of the data. These species work hard to find a local optima. • Distribution models: These types of mergers are grounded on the postulation that all data points [11] in a collection are subject to the same dispersal (Example: General, Gaussian). These species often suffer excessively. A popular example of these types is the Expectation–maximization algorithm that uses many common distributions. • Density Models: These models search for data space locations for an eclectic of data points [11] in the data space. It divides the different regions of quantity and assigns data points within these regions into one group. Popular examples of congestion models are DBSCAN and OPTICS [12]. 3.4 Cluster Formation Methods It is not mandatory that clusters designed after applying the technique will be of spherical shape. Followings are various additional cluster formation methods: • Density-based: Here, in this technique, the groups or clusters are designed as the dense region. The benefit is that it provides decent precision as well as decent proficiency to amalgamate two clusters. Eg: Ordering Points To Identify the Clustering Structure (OPTICS) [12] etc.

• Hierarchical-based: The cluster is formed based on hierarchy in the form of tree type structure in this technique. There are two categories namely, Agglomerative i.e. Bottom up approach and Divisive i.e. Top down approach. Eg: Balanced Iterative Reducing and Clustering using Hierarchies [13] (BIRCH), etc. • Partitioning: The cluster is formed into k clusters by portioning the object. Number of partitions is equivalent to the number of [7] clusters. eg: K-means algorithm, Clustering Large Applications based upon Randomized Search (CLARANS) [14]. • Grid: The clusters formed are grid like structure. The clustering operations which are done on grids are expeditious and independent of the number of [7] data points which is an advantage for these methods. eg: Clustering in QUEst [15] (CLIQUE). 3.5 Clustering Algorithms: The three discrete categories of clustering algorithms [4] mentioned are K Means Clustering, Agglomerative hierarchical clustering, Density-based spatial clustering (DBSCAN). K Means Clustering K-means is the least difficult unsupervised learning algorithm that solves the well-known clustering problem. The method follows a straightforward and simple approach to organise a particular dataset through a specific number of clusters (accept k clusters) fixed apriori [16]. The primary thought is to characterize k centers, one for each bunch. The better decision is to put them at a distant away from each other. The following stage is to consider each point of the given dataset and correlate it to the closest center. When no point is forthcoming, the initial step is finished. Now there is need to analyze the k new centroids as the barycenter [16] of the clusters that would provide result from the previous step. After acquiring the k new centroids, a new binding needs to be done between the identical dataset points [11] and the nearest new center. A loop is generated. As it turns out the loop may notice that k centers modify their position gradually step by step until no variations are to be done or the centers do not shift any more. The algorithm targets at minimizing an objective function know as squared error function which is given by: J (V ) =
ci c xi − vj2 i=1 i=1
where, ||xi − vj|| is the Euclidean distance [17] between xi and vj. ci is the number of [7] data points in ith cluster [17] c is the number of cluster centers [17].

Agglomerative Hierarchical Clustering Clustering types also encompass partitional clustering which split the dataset into a preferred number of [7] clusters. The dataset is first assigned to a single cluster which is further divided until all clusters containing a single instance are called as divisive hierarchical clustering (DHC). Each instance is initially assigned to a distinct cluster and the closest clusters are then agglomerated until all instances are contained in a particular cluster is called as agglomerative hierarchical [2] clustering which is an opposite approach of DHC (Fig. 1).
Fig. 1 Agglomerative hierarchical clustering
The benefit of the algorithm is that it can churn out the categories of the objects, which may serve as enlightening for statistics display. The smaller clusters which are generated may be helpful to establish the resemblance between prototypes and data points [11], and it operates well only in. The constraints faced are, some constraint amalgamations when applied with agglomerative algorithms can affect the dendrogram to stop impulsively in a dead-end elucidation even though other feasible solutions exist with a smaller amount of clusters. When constraints escort to competently solvable feasibility problems and do not give a dead-end solution, we can then illustrate the profits of benefitting constraints to enhance cluster purity and [18] average distortion. DBSCAN DBSCAN algorithm or the Density based spatial clustering of application with noise [8], is a density based method which can detect the arbitrary shaped clusters where the clusters are demarcated as the dense regions disconnected by low dense regions [19]. This methodology begins with a random arbitrary object present in the dataset and verifies its neighbouring objects within the given radius (Eps) set by the user. If the neighbouring objects within that Eps are more than the [8] minimum number of objects required for a cluster, it is marked as a core object or the core point [8]. In case the neighbouring objects it surrounds within given Eps are less than the minimum number of [8] the objects required, then such points are marked as noise or the outliers.

Due to this, this algorithm can determine which information or points should be categorised under an outlier. The DBSCAN algorithm can recognize the clusters of large spatial datasets observing the local density of wedges of data using a single input parameter. Furthermore, the user gets a recommendation for the parameter value which would be appropriate. An example of a software program that has the DBSCAN algorithm implemented is WEKA [8]. The DBSCAN clustering algorithm can be categorised as following. Detection Based DBSCAN clustering: This technique is the most simple detection problem as it can be solved proficiently as an upper bound on a discredited likelihood function. It is a helpful algorithm as it recovers maximum number of likelihood of sides and orientation at locations of the most likely polygons the first stage of the detection is posed as a discrete Hough-based algorithm. The second stage takes an approximation to the full likelihood function to recover orientation [20] and number of sides. Hierarchical DBSCAN clustering: Hierarchical DBSCAN clustering is one of an approach of cluster analysis which builds a hierarchy of clusters. The tactics for hierarchical clustering mostly fall into two categories: In hierarchical clustering the data are not partitioned into a particular cluster [20] in a single step. Instead, a series of barriers takes place, which may commence from a single cluster encompassing all objects to n clusters each comprehending a single object. Spatial–temporal DBSCAN clustering: It is a fresh clustering algorithm which is premeditated for storing and clustering a widespread range of spatial–temporal data [20]. Distinctive functions were developed for data amalgamation, conversion, visualization, analysis and management. It is indexed and salvaged according to spatial and time dimensions. A time period is attached to the spatial data to display the time validity or storage information in the database. A temporal [20] database may aids valid time, transaction time or both. The valid time signifies the time period during which the statement carries the validity with respect to the real world. The transaction [20] time is the time period during which a fact is stored in the database. Partitioning based DBSCAN clustering: This method of clustering, generally yields in a set of N clusters, each object fitting to one such cluster. Each cluster is exemplified by a centroid or a cluster. The precise form of this explanation will depend on the kind of the entity which is being clustered. In cases where real-valued data is available, the arithmetic mean [20] of the attribute vectors for all objects within a cluster provides an apt representative. If the number of the clusters is more, the centroids can be further clustered to produce [20] hierarchy within a dataset. Incremental DBSCAN clustering: This clustering algorithm basically handles the dynamic databases. It has the capability to change the radius threshold [20] value dynamically. The algorithm confines the number of the final clusters and only once reads the original dataset. Simultaneously, the algorithm introduces the frequency data of the attribute values. It can be used for the categorical [20] data. Grid-based DBSCAN clustering: This approach quantizes the dataset into a certain number of cells and operates with objects belonging to these particular cells. The method

does not displace the points but rather build several hierarchical levels of the groups of objects. The unification of grids and subsequently clusters, does not depend on a distance measure. It is determined by a predefined [20] parameter. 3.6 Different Comparison Metrics See Table 1. Table 1 Comparing metrics Feature/Algorithm

If the value of S is close to 1, then the point belongs to the correct clusters. ii. If the value of S is close to 0, then it indicates that the point is in the overlapping clusters. iii. If the value of S is close to −1, then the point belongs to the incorrect clusters and should be assigned to the other clusters. The higher value of Silhouette Coefficient score associates to a model with enhanced defined clusters and well separated. Davies–Bouldin Index The Davies-Bouldin index [22] (DB) is deliberate as follows—for individual cluster C, the resemblances between C and all other clusters are computed, and the highest value is assigned to C as its cluster similarity [24]. Then the DB index can be attained by taking an average of all the cluster similarities. The smaller the value of index, better the clustering result. By abating this index, clusters are the most distinct from each other, and therefore achieves the best partition [24]. The formula for Davies–Bouldin index is given by: ⎫ ⎧⎡ ⎤ ⎬ ⎨ 1 1 1 maxj,j=i ⎣ d (x, ci) + d (x, ci)⎦ d (ci, cj) (3) ⎭ ⎩ ni x∈c NC ni x∈c i

j
where, D: data set [22]; n: number of objects in D; c: center of D [22]; Ci: the ith cluster [22]; NC: number of clusters; ni: number of objects in Ci; ci: center of C [22]. The minutest score of Davies–Bouldin index is zero, with the lower values signifies enhanced clustering of the points. The various advantages of this index are that the computation of Davies–Bouldin is much straightforward than Silhouette scores and the index computes only magnitudes and characteristics intrinsic to the dataset. One of its drawbacks is the use of centroid distance limits the distance metric to Euclidean [17] space.

Calinski-Harabasz Index The Calinski-Harabasz index depends on the concept that good clusters or points are always compact in nature and have distinct space between them r. The Calinski-Harabasz index (CH) [25] assesses the cluster validity based on the average between and within the cluster sum of squares. The formula for this Index is defined as: i ni d 2 (ci, c)/(NC − 1) i kCi d 2 (x, ci)/(N − NC)
(4)
where, D: data set; n: number of objects [22] in D; c: center of D; NC: number of clusters; Ci: the ith cluster; ni: number of objects in Ci [22]; ci: center of C. Higher the value of this index, better is the clustering model compared to others. One of the drawbacks of this index is observed that the value of index is in general higher for the convex type of clusters than other types of clusters, such as density based [8] clusters which are obtained through the DBSCAN algorithm.
4 Implementation 4.1 K-means Algorithm K - Means uses the Euclidean distance [17] method to compute the distance between the clusters. For the implementation, we first initialize the k points called means. Then we compartmentalize each data point to its closest mean and we transform the mean’s coordinates, which are the averages of the data points classified in the mean so far. We repeated the process for a given number of iterations and at the end, we obtained our required clusters. To decide how many clusters to consider, we can employ several distance calculating methods such as the elbow [26] curve method, BIC score with a Gaussian Mixture Model, etc. For our dataset, we have used the basic and most widely used method the Elbow Curve method. In this method, wherever we observe a “knee” like bent formed by the lines, we consider that number as the ideal figures of clusters in the K-means algorithm (Fig. 2). Here, we did the graphical visualizations between the sum of the squared differences and the K-mean values to find the number of clusters. Afterwards, we fitted our scaled data into a K-means model having 3 clusters, and then labeled each data point (each record) to one of these 3 clusters. We then calculated the number of records in each cluster (Fig. 3).

Fig. 4 Child mortality versus gdpp
After that we checked our model, using the Silhouette score, Davies Bouldin and Calinski-Harabasz Index and visualized the clusters formed between child mortality and gdpp (Fig. 4). From the above graph, we can conclude that the country having high child-mortality and low GDP [10] per capita (measurement of the annual growth frequency of the Total
230
K. Shrikant et al.
GDP) is an under-developing country, the country having low child-mortality and high GDP per capita [10] is a developed country. Here, in K- means algorithm, we conclude that 0 depicts an under-developing country, 1 depicts a developing country and 2 depicts a developed country. 4.2 Hierarchical Clustering Divisive and Agglomerative are two classifications of hierarchical clustering. We have used Agglomerative Hierarchical Clustering because it is the most generic type of algorithm that is used to congregate objects in clusters according to their similarities. This a bottom-up approach [27], each observation starts in its own cluster, and pairs of clusters are merged as one moves up the hierarchy. A Dendrogram [9] is a type of tree diagram that indicates the hierarchical relationships between different sets of data. We plotted the dendrogram on the dataset (Fig. 5).
Fig. 5 Dendrogram
From the above dendrogram we can take the minimum number of [7] clusters as 2 and maximum number of clusters as 5. As we can see from dendrogram 3 in the right no of clusters, so we are going to take 3 no of clusters. We fitted the scaled data into an agglomerative hierarchical model and then labeled each data point. After that we visualized using scatterplot between child mortality and GDPP (Fig. 6). Here, in an agglomerative hierarchical clustering algorithm, we conclude that 0 depicts an—developed country, 1 depicts a developing country and 2 depicts an underdeveloping country. 4.3 DBSCAN Algorithm DBSCAN is an abbreviation of “Density based spatial clustering of applications with noise [8]”. This algorithm convenes the data points that are immediate to each other based on Euclidean distance [17] and a minimum number of [7] data points. It also denotes noise as outliers (noise means the points which are in low-density regions). For implementation, we dropped the country feature from the dataset and converted it

into distance matrix form using the numpy array. Then we applied data transformation to the dataset by scaling the data using StandardScaler and fitting the data and then transforming it. The DBSCAN algorithm [3] was implemented using eps as 1.38 and min_sample = 9. Data fitting was applied on the DBSCAN algorithm and we further calculated the number of records in each cluster (Fig. 7).
Fig. 7 Count DBSCAN
In the subsequent step, we calculated the core points or the core sample, the data points that are within a dense region of distance eps and calculated the number of [7] clusters formed keeping −1 as the outlier. We visualized the dataset using the seaborn scatterplot between child mortality and gdpp (Fig. 8). Here, in the DBSCAN algorithm, we conclude that 2 depicts an under-developing country, 0 depicts a developing country and 1 depicts a developed country.
5 Result On implementing the various measures of clustering performance such as the Silhouette score, Davies–Bouldin index and Calinski–Harabasz index, it is evident that the Agglomerative hierarchical algorithm is better than the K-means and DBSCAN algorithm. When comparing the algorithms on the base of the Silhouette score, K-means outperforms agglomerative clustering and DBSCAN algorithms based on all cluster validation metrics (Table 2).

When compared with Davies–Bouldin and Calinski–Harabasz index, Agglomerative hierarchical [2] clustering algorithm outperforms DBSCAN and K-means algorithm. The Davies–Bouldin index states that the algorithm having minimum score i.e., near zero indicates better clustering and the Calinski–Harabasz index states that higher the score of the algorithm, better is the performance and clusters are dense and well separated (Fig. 9). To further assist our outcome, we compared the three clusters of countries that were formed-developed, developing and under-developing countries. We discovered that certain developing countries in 2017 according to the United Nations [10], Botswana and Angola are developing countries. In Agglomerative hierarchical [2] clustering algorithm, Botswana and Angola is under developing country but according to K-means algorithm, they are categorised as under-developing country whereas in case of DBSCAN algorithm, they are identified as an outlier and so are not under any of the three clusters.
6 Future Scope This paper was intended to compare certain data clustering algorithms such as K-means algorithm, Agglomerative hierarchical [2] clustering algorithm and DBSCAN algorithm. In this paper, we have anticipated a smaller dataset for now and so for the future work, we will work on a larger dataset to obtain efficient high-quality clusters. Furthermore,

the comparisons among the aforesaid three clustering algorithms endeavored by sundry factors other than those contemplated in this paper. To enhance the comparison we will work on the additional variety of clustering algorithms such as—K medoids clustering algorithm, Divisive Hierarchical clustering algorithm, Make density based clustering (MDBC) [5] algorithm etc.
7 Conclusion To conclude, the most widespread applied clustering algorithms such as K-means, Agglomerative hierarchical clustering algorithm and DBSCAN were applied on the dataset. The performance of a particular clustering algorithm depends on the dataset that is selected. In our case, agglomerative hierarchical clustering worked more efficiently than DBSCAN algorithm and K-means algorithm. Since the K-mean algorithm is a centroid based algorithm, it is more sensitive towards the outliers because a mean is easily influenced by the extreme values. In our dataset, we have data points [11] that form groups of capricious density, thereby resulting in the DBSCAN algorithm to not work more efficiently as it does not cluster the data points [11] well. Since the clustering in DBSCAN depends on Eps and minimum number of points [8] parameters, they cannot be opted separately for all clusters. The limitations of the country dataset that it consists of many outliers but since our dataset is small (167 rows only) we did not remove the outliers as it will further reduce the number of rows.

Refactoring Faces Under Bounding Box Using Instance Segmentation Algorithms in Deep Learning for Replacement of Editing Tools Raunak M. Joshi(B) and Deven Shah Thakur College of Engineering and Technology, Mumbai, MH, India
Abstract. Immense amount of funds and time are being invested in video and photo editing. This has an involvement of resources in a high number. Software as well as hardware. Software is handled by an entire editing team. Hardware is used for the purpose of supporting the editing tools. Resource exhaustion is the main cause and is detrimental for the reach of the organization. The work that we present in this paper describes an approach for the problem. Deep Learning is being used as a replacement for a lot of heavy ended monotonous work. Under this notion, the same can be extended to this specific problem. Automating the problem using Neural Network intended for Image Processing applications. This network will directly do all the necessary amount of work and refactor the entire image and video without using any specific tool or special effect. Keywords: Deep learning · Image processing · Image segmentation · Object detection
1 Introduction Deep Learning has proved to be a successful discovery pertaining to Machine Learning and Statistics. Deep Learning [1] is a non-parametric predictive analysis approach and constitutes all aspects of Machine Learning as its building blocks. It is a blend of mathematical concepts such as Inferential Statistics, Linear Algebra and Calculus. A standard Deep Learning approach is performed using an Artificial Neural Network [2]. These Neural Networks are inspired from the human brain’s biological neural networks. These Artificial Neural Networks are abbreviated as ANN and have become Dense with respect to time. Dense networks have more number of activation layers. This promotes a better learning approach for the network. A standard Deep Neural Network is made up of two phases. These phases are Forward Propagation [3] and Backward Propagation [4, 5]. Forward Propagation is the process where one computes the necessary parameters for learning. Backward Propagation is the process where the Neural Network computes the loss and tries to converge it. Any standard Neural Network consists of one input layer, one output layer and several hidden layers in between them. These hidden layers differ in parameters with respect to data. Every input layer takes the input data in the form of a matrix. These values in the matrix © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2022 V. E. Balas et al. (eds.), Intelligent Computing and Networking, Lecture Notes in Networks and Systems 301, https://doi.org/10.1007/978-981-16-4863-2_20

are the features of data. The input layer will arrange the matrix in a single long vector which holds values sequentially. The values in the vector will interact with all the neurons of the layers. These neurons are responsible for holding and learning the parameters. All of the neurons will be intertwined with the neurons in the preceding layer. The output layer is the last layer which gives a distinct value with respect to the values in the labels. Each and every single layer has the values from intertwined neurons in the form of weights. These weights are multiplied with feature values. An arbitrary seed value known as Bias is also added to it. The task of Bias is to maintain an absolute value of the equation as Neural Networks do not perform efficiently with negative values. This entire function is inference of every single neuron. It is later given to an Activation Function. It is used to generate the values of every single hidden layer. A standard activation function is a high level mathematical function like Rectified Linear Unit, Tangent Hyperbolic or Sigmoid function which is responsible for learning all the parameters with respect to that layer. These values are then given as inputs to next layers. The entire procedure that you read so far now is the forward propagation. So backward propagation is another side of coin. The neural network often does learn all the parameters in the first pass. So, there is a significant loss of information which can be retained using the backward propagation. The backward propagation calculates the loss [6] using metrics and then tries to apply loss optimizers. These loss optimizers [7] are high end mathematical functions designed for converging the loss. These loss optimizers are known as converging algorithms. The most common type of loss optimizer in deep learning is Gradient Descent [8]. Calculus is the basis of this algorithm. The backward propagation uses loss optimizers and tries to converge the loss generated in earlier activation layers. So basically, the entire neural network reiterates to generate the desired output. This single pass of one forward propagation and backward propagation is considered as one epoch. Standard state-of-the-art neural network has several epochs.
2 Methodology The methodology we prescribe in this paper is concise study of methods we used to solve the problem statement. The problem statement expects to design a Deep Learning Network that will substitute the traditional editing procedures of Noise Induction. This will prevent resource exhaustion of software as well as hardware. The methodology concentrates in the area of Image Processing. The applications of Image Processing in Deep Learning are solved using Convolutional Neural Network [9–11]. The method of Convolutional Neural Network works with a fully functional neural network that takes the input as images and gives desired output. The convolutional neural network works like a typical neural network with convolutions and max pooling as a feature extraction mechanism for activation layers. This discovery was groundbreaking yet in our system we require something more precise (Fig. 1). The first approach we considered was using the Object Detection Method formulated specifically for Deep Learning. Object Detection was a good start as we wanted something specific that can detect faces from videos or images. The object detection works on the dynamics of the bounding boxes. These boxes are able to detect the objects

with cascades. We were fortunate enough to find an Object Detection Algorithm specifically designed for Deep Learning. You Only Look Once abbreviated as YOLO [12] is a high dimensional object detection algorithm designed for deep learning. The bounding boxes scavenge for objects in every single frame. The overlapping boxes are spotted by Intersection over Union (IoU). YOLO was an appropriate kickstart algorithm for our problem as we would detect the faces in our video frames (Fig. 2).

Object Detection only works for Detection mechanism but our problem wanted something more precise. Image Segmentation was a better approach as we wanted to extract specific units from the input. Image Segmentation is far varied from detection as the detection only spots an object in a frame and gives output. We specifically wanted

239
to separate the frame from the entire portion of video and induce noise in it. But before finding specific object detection and image segmentation amalgamation we decided to search a standard image segmentation algorithm. The first algorithm that we came across was Deep Residual Network [13]. It is also known as ResNet commonly. The ResNet works on Residual Representations and Shortcut Connections. It was designed on the basis of the famous DenseNet [14]. ResNet definitely has limitations but it was our premise to move further for a search of more developed form of Image Segmentation Deep Learning Algorithm (Fig. 3). In order for a better curated solution we also took autoencoders into consideration. An advanced network with multiple stacked layers might not always be reasonable and can promote poor space and time complexity. Under this contention we started our search along with autoencoders and we came across U-Net [15]. It was designed for Biomedical Image Segmentation and was very powerful. It is not a form of traditional Convolutional Neural Network. It is a very dense convolutional autoencoder. It works on the skip connections concept and has over 30 million parameters (Fig. 4). As the search for an improved image segmentation algorithm was satisfactory after UNet, failed to foresee an important point. Driven by the Image Segmentation algorithms we did not take an object detection basis. U-Net is an image segmentation algorithm, but it is a Semantic Image Segmentation approach. We wanted something that could specifically create separation in the input frame. This was viable with only the Instance Image Segmentation approach. This concept was thoroughly shed light on in Conditional Random Fields Meet Deep Neural Networks for Semantic Segmentation [16]. It points out the major differences of semantic and instance segmentation (Fig. 5). The first instance segmentation algorithm that we came across was R-CNN [17]. It is an amalgamation of the object detection and image segmentation. The issue was it was a semantic segmentation algorithm but we had to keep in pace with our main motive. Since only focusing on instance image segmentation was detrimental, we had to consider algorithms that are designed to handle both the tasks. R-CNN is a high dimensional Convolutional Neural Network that works on Region. It performs its operations using the bounding box regression method. It is a very mature and vast network which gave us a new vision for our problem (Fig. 6). We had an intuition that R-CNN would not be able to provide us everything we were looking for. The computational time required was very high. The algorithm was for sure a new start for overcoming problems but required well designed optimization for efficiency. The computational efficiency was quite poor when compared to YOLO. We wanted an algorithm that would provide computational ability as that of YOLO but get the job done. In that fashion we found an algorithm named SPP-Net which was quite better than R-CNN, but was a visual recognition algorithm and Image Segmentation statement would again digress. After a thorough search we were able to find Fast R-CNN [18]. This was designed by the same author who contributed towards R-CNN. The Fast R-CNN uses a multi-stage pipeline that promotes Region of Interest (RoI) [19] pooling layer. It has a truncated SVD for faster detection. SVD is an abbreviation for Singular Value Decomposition [20]. It trains a very deep VGG-16 [21] network which is 9 × times faster than traditional R-CNN.

Later our search for a more advanced network ended up with Faster R-CNN [22]. It is the fastest R-CNN discovered. It is even faster than Fast R-CNN. Region Proposal Network is the principle of Faster R-CNN. The authors successfully merged the both, i.e. Region Proposal Network (RPN) and Fast R-CNN. It continuously detects all the objects and their respective probabilities at every instance (Fig. 7). The next thing we wanted was a real-time instance segmentation. This was possible when our search came across the Yolact algorithm [23]. It was the most appropriate

algorithm for our problem because it was able to cover all the criterions. It produces robust high-quality masks. The prototypes for masking have been induced in this network. The prototype generation branch also known as protonet predicts a set of n prototype efficient masks for the entire input. It was the last network we came across that was able to match our problem statement (Fig. 8).

3 Implementation Since we were able to find a network as our basis, the designing of the network from scratch was eliminated, but the task of noise induction was there. We started working on the method of decolorization. Since Yolact creates high-quality masks which are separated by color codes as per the detected instance segmentation and objects. The idea was to decolorize the masks by making RGB codes to zero. Although decolorization happens but we wanted faces specifically. An extension to this problem was achieved

by reducing the box size and removing masks. This approach would more or much be different than traditional transfer learning. As we were looking forward to reducing the computational complexity, we can use the transferred weights and make changes in the last layer. The noise induction has many different techniques but we decided to go with the most basic i.e. Gaussian Noise [24]. It is a statistical noise having a probability density function. The Yolact issue of a pretrained model using COCO dataset [25] as the current approach using ImageNet [26] is nearly impossible due to lack of computational power. The weights are provided by the author. The backbone we used for weights is Resnet50FPN [27]. Transfer learning [28–30] was performed by adding Gaussian Blur in the output layer. Mask was specifically compressed for faces and then noise was added (Figs. 9, 10, 11, 12, 13 and 14).

4 Conclusion In this paper we were able to find an approach to tackle the problem for replacing editing tools for blur effect. Considering the fact, this paper imposes a curated hypothesis of various deep neural networks which can help one reach the desired outcome. Our approach in this paper creates a pathway for readers to solve the problem with images as well as videos. The project uses instance image segmentation algorithm with transfer

Abstract. In the era of the internet and with an expanding number of individuals as its end users, countless trespassers are presented every day. In 2016, four Pakistani terrorists illegally entered into the Indian army base and carried out grenade attacks on the security forces. Thus, tracking the movement and the location of different trespassers and intervention of unknown or unauthorized persons with the assistance of Intruder Detection Systems is the proposed work in this paper. Intruder Detection System is a developing pattern in research in today’s technological world. Existing investigations and with their use of technology show adequacy and poor approaching ability of AI in dealing with Intruder Detection Systems. In this research paper, we intend to clarify and improvise the identification pace of Intruder Detection System by utilizing OpenCV a built-in library in python. Keywords: OpenCV · Image thresholding · Image smoothing · Contours
1 Introduction Now a day’s human behaviors and their activities are more important in surveillance. To identify and tracking the human behaviors is the main factor of video surveillance system. To identify the persons entering into the prohibited or restricted places and to identify the activities happening in the crowded places video surveillance system is used mainly because one person cannot identify the total activities happening in a crowded place or any restricted places entering and he cannot monitor all the time. These days we have CCTV cameras all over the areas for the security purpose but there is no alert system if any intruder enters into a restricted area without permission or access to enter into an area. The CCTV cameras just records the video and the person cannot sit in front of the screen all the time so to avoid that the detection system is used as if any intruder enters into an unauthorized place, it sends an alert so that the authorized person can be alert and know that an intruder has entered. The main motivation behind this research paper is the alarming rate of crime rate in India. As the intruders entering into the prohibited or restricted places so we can’t find easily what exactly the intruder is doing by entering into the prohibited places. So, to avoid this problem we are coming up with the motion alert and detection system in which if the intruder enters into any restricted or prohibited areas then it immediately sends an alert to the registered authorized persons. It is also used to control the crime rate. It is implemented by using OpenCV with python. As there is a rapid increase in technology it is easy to identify the intruders or any suspicious © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2022 V. E.

activities happening around it is easy to identify through video surveillance system and it reduces the man work. For a person it is very difficult to identify and analyses the behavior of human activities and it is difficult to identify between a usual person and an unusual person so by video surveillance system it is easy to identify. The main goal is to reduce the crimes and threaten events. Main task is to see that unusual events can be located by using this surveillance system which can be manual or automatic. “Motion Detection and Alert System” is a software application which is used to identify the intruders/ unauthorized persons from entering into the unrestricted or prohibited places. We can detect the intruder entry by detecting the motion of any person entering the area. If a person is detected the it will send an alert that intruder is detected then the authorized persons can get the information about the intruders and get alerted and take necessary steps to avoid unusual events happening in the early stages. We can store the data of the persons entering into the prohibited areas and we can identify later if the person again enters into any other prohibited places and it is easy to identify him. This can be done by using OpenCV with python. This can be very accurate in identify the intruders entering into the prohibited or unrestricted areas.
2 Related Study The already existing systems are using thermal cameras for intruder detection [1, 2]. In the most unfavorable weather conditions, there is a rise of a tool that is used for seeing in the darkness that is Thermal Imaging. It is helpful for detecting thermal energy which is further released from the object. Thermal imaging cameras provide images/pictures of an invisible infrared radiation. Based on the temperature differences between the objects, thermal imaging will produce a crisp image/picture on which the smallest of details can be displayed [3]. Thermal imaging cameras will work both while night time and daytime. Uma maheswari et al. (2020) has proposed maximum edge patterns for facial expression analysis [4]. 2.1 Advantages 1. 2. 3. 4. 5.
It can be used daytime and night time. It uses data from PIR sensors. It works in almost all-weather conditions. It can be blocked by any shielded by any physical objects. It can see within the light fog, smoke, & rain.
2.2 Disadvantages 1. 2. 3. 4. 5. 6.
It does not have any physical barrier. It cannot identify intruders. But it can spot them. [5, 6]. Thermal images cannot be captured through certain materials like glass and water. High Cost. There are several techniques by which the image capturing can be restricted. Using blanket technique, we can directly bypass the temperature recordings.

3 Proposed Model The proposed system uses OpenCV to identify and detect any unusual entry of intruders in the restricted area. This technology is cost-effective. The input video is passed through the OpenCV code that is developed for the purpose of Intruder Detection and Alert Authority. The input video firstly goes under pre-processing then the features are extracted [7]. At this point, if an intruder is detected then the OpenCV code sends the alert mail to the authority as well as the output video is also generated and stored in the local storage. The output video is also generated if the intruder is not detected (Figs. 1 and 2).

To generate the status in the output video generated. 3.2 Proposed Model Outcomes 1. Accessing dynamic input and produce output video. 2. If a person is detected in the prohibited area, an alert mail is sent immediately to a concerned team. 3. Date and Time Stamp are detected and are attached to an alert message.

4 Experimental Setup 4.1 Sensors from Which Data is Taken The data for the project is taken from CCTV or any video recording devices or visible light sensors. 4.2 Taking Video Input In order to detect motion, we should take video as input. Upon starting the program, the user will be prompted to select the video which is to be given as input.

4.3 Motion Detection The main objective is to detect the motion in the video, it is detected by calculating the absolute difference in the frames read by the program, if the absolute difference between the frames is more than the experimental value then we say that motion is detected in the video [8, 9]. 4.4 Sending Mails After detecting motion in the given video, the user should be alerted via email, in order to send a mail to any person using SMTP library, we should provide mail id and password and port number to the methods provided by the library. 4.5 Local Storage The video will be stored in the local system and when a motion is detected it show the status on the video screen as well as there will be marked boundaries around the object (Figs. 3 and 4)s.

6 Experimental Procedure A certifiable framework for Human Motion Detection and Tracking mainly, this module requires capacities and calculations written in the Intel’s open CV library. In the equipment’s viewpoints, we had utilized cc television camera recordings for testing purposes and usage of movement location. The exploratory system follows a few stages.

6.1 Pre-processing The OpenCV work ’Video Capture’ imports video from a related camera. In this, every information diagram has 640 × 480 pixels with a 3-layer (red, green, blue) RGB concealing plan. The system changes over the caught picture from RGB concealing association to diminish scaled space that has recently a solitary tone for every pixel. This movement shortens the proportion of computation and appropriately enables consistent use [10, 11]. 6.2 Simple Thresholding For every pixel, comparative edge regard is applied. If the pixel regard is humbler than the edge, it is set to 0, else it is set to the best worth [12, 13]. The limit CV breaking point is used to apply the thresholding. The primary dispute is the source picture, which should be a grayscale picture. The ensuing conflict is the breaking point regard which is used to organize the pixel regards. The third conflict is the most limit worth which is given out to pixel regards outperforming the cutoff [14]. The possibility of thresholding is to encourage rearrange visual information for investigation. To begin with, you may change over to dark scale, yet then you need to consider that grayscale actually has in any event 255 qualities. What thresholding can do, at the most essential level, is convert everything to white or dark, in view of a limit esteem. Suppose we need the limit to be 125 (out of 255), at that point all that was 125 and under would be changed over to 0, or dark, and everything over 125 would be changed over to 255, or white. On the off chance that you transform to grayscale as you typically will, you will get white and dark. In the episode that you don’t change over to grayscale, you will get thresholder pictures, yet there will be shading [15, 16]. 6.3 Smoothing As in some other signs, pictures additionally can contain various kinds of commotion, particularly in light of the source (camera sensor). Picture Smoothing methods help in diminishing the commotion. In OpenCV, picture smoothing (likewise called obscuring) should be possible from numerous points of view. In this instructional exercise, we will get the hang of utilizing the Gaussian channel for picture smoothing [17]. Gaussian channels have the properties of having no overshoot to a phase work input while restricting the climb and fall time [18]. As far as picture handling, any sharp edges in pictures are smoothed while limiting an excess of obscuring. Removing disturbance and separation of individual components and joining different components in a picture. As well as finding of boundaries or openings in a picture [19, 20]. 6.4 Finding Contour Forms can be explained basically as a twist joining all the predictable centers (alongside the breaking point), having a similar concealing or force. The structures are a useful device for shape assessment and article area and affirmation, Referred to as form. For better accuracy, use equal pictures [21]. So, prior to finding shapes, apply edge or watchful edge acknowledgement [18, 22]. In OpenCV, finding shapes takes after finding white thing from a dim establishment [23].

6.5 Contour Approximation It approximates a form shape to another shape with less number of vertices relying on the accuracy we indicate. It is a usage of Douglas-Peucker calculation [13, 24]. 6.6 Contour Area Contour territory is given by the capacity cv.contourArea() [25]. 6.7 Drawing Square Shapes and Output After finding the contours and retrieving NumPy array of contour coordinates, we have to calculate the area occupies by those contours and we have to observe and keep a record of these areas and after several experiments if area is more than 900 then it is concluded that motion is detected in the given frame. Drawing square shapes around the identified articles [26]. Now after detecting motion, in order to store the output indicating that motion is detected and status stating ‘Intruder detected’ will be written and output video is stored in the local storage [27]. 6.8 Sending Mails The smtplib module set out a Simple Mail Transfer Protocol client session item which will be utilized to send email to the Internet device with a ESMTP or SMTP listener daemon. Mails are sent to the client utilizing SMTP. Sendmail () [28]. 6.9 Experimental Data Used There are several types of experimental data like Raw Frames, Pre-processed Frames, Counter array, Counter Area, Email credentials. 1. The main source of data for the project is the feed taken from CCTV cameras and other type of video recording devices. 2. The experimental data will be in the form of frames which will be transmitted to several modules in the execution, first the data is read in the form of frames. 3. These frames are first pre-processed and are converted to readable frames. 4. The frame thus pre-processed is sent to thresholding to maintain the pixel balance. 5. The frames are dilated and are sent to counter retrieving. 6. The counter data is stored in to arrays and are sent for counter approximations. 7. After successful approximation, counter area is calculated which is used to determine motion.

6.10 Control Data The counter area calculated is the control data of our project. Based on the variation of counter data the motion detection is justified. As per calculations if counter area is greater than 900 then motion is detected.
7 Results and Discussions 1. The output data is in the format of video mode specified by the user and the video or the output is stored in the specified location as per the user specification and also the output video can be utilized for further references in the future such as face recognition etc. 2. No moving object can escape the proposed motion detection system, because visible cameras can’t be blocked directly using any material directly and also the visible detection is very powerful during the day time and there is also no loss of image during the transmission. 3. The proposed system on detecting the motion, sends an alert mail to the registered person which can be sent to anywhere in the world rather than the conventional system which produces mechanical sounds or an alarm which may not be that effective in terms of long-distance alert system. 4. The output data is in the format of thermal imaging for the thermal imaging for motion detection system because the images are captured through PIR sensors. 5. A straight forward strategy to impede IR is a conventional ‘space cover’, ‘crisis cover’ or warm cover. They are made of Mylar foil materials and will block IR and bomb the cameras to catch the readings [29]. 6. Symbolism Conventional motion detection systems which use thermal imaging mostly dependent on hardware hence produces signals to the antenna which may be of less distance and may not be that effective in nature. 7. The result obtained will be of specified qualities and formats as specified by the user while saving the video. 8. The video containing intruder gets automatically saved in the local machine, in which the program is being executed. 7.1 Existing System Outcomes 1. The output data is in the format of thermal imaging. 2. A straightforward strategy to obstruct IR is a customary ‘space cover’, ‘crisis cover’ or ‘warm cover. They are comprised of Mylar foil materials and it will impede IR symbolism. 3. Conventional motion detection systems which use thermal imaging mostly dependent on hardware hence produces signals to the antenna which may be of less distance.

7.2 Proposed System Outcomes 1. The output data is in the format of video mode specified by the user. 2. No moving objects can escape the proposed motion detection system, because visible cameras cannot be blocked directly using any material. 3. The proposed system on detecting the motion, sends an alert mail to the registered person present anywhere in the world.
8 Future Scope There is good scope for Motion Detection and Alert Systems. We can use this detection system in restricted places like military areas, there are prohibited areas like sectors present in military areas where all are not allowed to enter that area and in night times if anyone enters then it is difficult to detect who has entered, if we implement this system in such areas then it will be very easy to detect and it immediately sends the alert to the authorized persons so that we can respond immediately and we can prohibit them entering into that area. We can further use this system in Image processing, IOT for further purposes. If we can use this system in image processing then we can detect and differentiate the authorized and unauthorized persons and it gives the details of who has entered that region. Not only in military areas we can use it in museums, industrial compounds which is very useful to protect ourselves.
9 Conclusion This paper illuminates that all the problems, issues faced by the Human behaviors. In this paper we did the analysis of detection of intruders entering into the prohibited places such as abnormal behavior and motion detection. It detects the intruders which is recorded in CCTV camera. It can be used for security purposes further. This system is used to monitor the restricted areas in a better way. If in the restricted or prohibited areas if any intruder enters or if any motion is detected then it will send a warning mail to the registered authority along with time stamp. The output video in which the motion is detected is stored in the system itself for future references. This detection system is also very much secured to use and it detects the intruders very easily. There is decent scope for intruder detection using visible camera. Although thermal cameras are used for intruder detection, there are some flaws with thermal imaging. Utilizing warm covers—Less than one millimeter thick, the sheet retained 94% of the infrared light it experiences. Catching such an excess of light implies that warm articles underneath the shrouding material become undetectable to infrared indicators [30], so visible detection comes to the rescue. As technology is increasing, we can integrate face detection system which can be more effective. We can make multiple person’s detection we can detect the count of the person’s entering to any surveillance place and we can separate the authorized and unauthorized persons by saving their data in the database. In the future we can make a database and store the persons data in such a way that if the persons enter again into a prohibited place the data of that persons will be shown and the alert will be sent to all so that they can restrict the persons from doing any unusual things.

Abstract. This communication presents efficient focusing of radiofrequency for the non-invasive local hyperthermia treatment (HT) of breast tumors. Hyperthermia technique is used to raise the tumor temperature from 42–45 °C. In this combinational therapy, controlled heating at tumor site plays a vital role in the success of HT; else it creates hotspots on surrounding area of the treatment site. In this communication we are presenting mathematical analysis for the temperature distribution during the HT, Computational complexity for effective focusing of radio waves on tumor sites, and 2D modeling of breast model for testing the feasibility of HT. Pennes bio-heat equation is used for thermal analysis of tumor and healthy tissue in MATLAB environment, whereas thermal conduction parameters of 2D breast model are acquired from finite element method by imposing radiation, and convection boundary conditions. Heat flow modeling and electrostatic modeling of the 2D breast model with two tumors is carried out. 2D modeling result shows that HT is safe and reliable if temperature parameters are maintained in the safe limit, avoids hotspots on healthy surrounding tissue and reduces toxicity to a greater extent. Also, the obtained results for magnitude of electric flux density, heat flow in the tumors shows higher efficiency, with minimized hotspots.

1 Introduction Cancer is a disease, in which growth of cells in the body happens in an uncontrolled manner. It spreads very fast in other normal cells. Its uncontrolled spreading can result in death. Hyperthermia treatment (HT) is used to elevate the temperature of the tumor tissue artificially. Off late, researchers have been prompted to probe this noninvasive technique for the destruction of tumor cells. This technique involves heat irradiation [1]. The efficacy of hyperthermia treatment has been demonstrated for various types of cancer [1]. In HT, the temperature at a tumor site is kept in the range of 41–45 °C for the time duration of one hour or more. HT is used to damage and kill cancer cells.

to reduce the number of radiation treatments needed to cure the tumor. Clinically, HT also improves the effect of other cancer treatments like chemotherapy or radiotherapy when used in coalition on cancer patients [2, 3]. Before this treatment, a CT scan is performed to precisely locate the tumor region. Depending on the tumor’s location and stage of cancer, local, regional or whole-body HT is used to dispense heat to the tumor [4]. During local HT, a tumor area is heated superficially by the use of applicators. Superficial applicators of different shapes and types are positioned on the surface of superficial tumors with a contacting layer called a bolus. To avoid any side effects due to excessive temperature, rise at nearer skin area of the tumor, water flow in these boluses is concurrently used to maintain the temperature of the normal tissue skin nearer to the tumor at about 37 °C. Electromagnetic linking between applicators and tumor tissues is provided through these boluses attached to applicator. Thermometers are connected through tubes or needles to observe the temperature of the anesthetized tumor tissue [5]. Breast cancer, one of the most common and highly prevalent forms of cancer, leads to over five lack deaths worldwide every year [6]. This social issue motivated many researchers to investigate noninvasive alternative for the breast cancer treatment. From the experimental investigation and validation by Phong et al. in [7–12], HT with controlled focusing of microwave energy at tumor position is best option for the breast cancer patient [7]. In the implemented model of breast cancer [8], antenna excitation amplitudes and phase excitations are controlled using thermal analysis of tissue temperature to avoid hotspots in healthy tissues [9]. 3D focusing techniques of microwave energy gives better focusing effects than 2D focusing techniques [9]. A fabricated breast phantom model [10] is used for experimental implementation and validation of HT. Coupled simulation of MATLAB and CST microwave studio software has been carried out using the particle swarm optimization computational technique on a woman breast phantom, fabricated with actual mass material properties [11, 12]. Modern RF and microwave heating devices with phased antenna array has advanced settings to control optimized focusing of microwave power on tumor to minimize hotspots. Treatment planning is an important aspect to get best results of locoregional HT [13]. Figure 1 Shows the block arrangement for HT system.

Section 4 concludes this article with optimum temperature distribution on the tumor sites.
2 Mathematical Modeling and Analysis for Hyperthermia HT requires a deep understanding on thermal, electromagnetic as well as the biological characteristics of human tissue. This coupled mathematical analysis is used to model the HT in simulation environment. 2.1 Equations for Effective Temperature Distribution The bio-heat equation for tumor domain is given by Eq. 1 [14]. ρc

The aqueous solution and the intracellular medium have a velocity difference which is represented as a correction parameter for the compensation of this velocity difference. α-where, α-a correction parameter used for compensation of velocity difference between the aqueous solution and the intracellular medium, P-power dissipation of particles per unit volume, T -absolute temperature of body tissue, ρ-denotes the density of tissue, cdenotes specific heat of body tissue, k-represents the thermal conductivity of body tissue, ρb -blood density, cb -blood specific heat,ωb -perfusion rate of blood, Tb -temperature of blood, Qm -metabolic heat per unit volume, αP-effective power dissipation inside the tumor region.

The HT exposed tumor area having temperature in the range of 41–45 °C. In closed boundary condition, 15 square inch effective bounded area is divided in finite element of maximum node size, described in Sect. 2.3. This numerical approximation gives high accuracy in the modeling with minimum error in variation of temperature. Equation 3 represents the sum of square of temperature error. 1 Error = .

where, ϕ-field distribution within the studied tumor object, d- distance between the antenna elements, ξ in terms of antenna array are the ones that need to be optimized according to Eq. 4.

→ The fitness factor is the ratio of the power dissipated inside tumor (Qt (− ϕ )) to the − → power dissipated inside healthy tissue (Qh ( ϕ )) per unit volume. An antenna array produces it. This ratio should be maximum to achieve the higher power dissipation inside the tumor region given in Eq. 6. → maxf (− ϕ)=

To achieve the better exposure of radio frequency on the tumor, we need to cover the full volume of tumor at 42 °C and more. The difference between total tumor volume (Vtot ) and the volume inside the tumor at which the temperature is 42 °C should be minimum, given in Eq. 8. ◦C (8) min f ( α ) = Total Volume (Vtot ) − V42 α ) tumor ( This optimization parameter is scaled for four antenna arrays shown in Eq. 9. − → α = (α1, α2, α3, α4 )

2.2 Equations for Computational Optimization This section discusses the optimization of computational load, the iterative optimization method, Alternating Direction Implicit (ADI) method, is used to solve the partial differential bio-heat equation for different heating and cooling time variations.

where, ∂T ∂n -heat emission density, where, ksb is a Stephan-Boltzmann constant, β is an emissivity coefficient, and T0 - ambient radiation temperature. Parameters β and T0 may differ from part to part of the boundary. The tumor tissue surface temperature is 37–42°C with applied boundary condition of hyperthermia treatment. The tumor tissue is modeled with specific heat capacity of 3.75 kJ/g°C, thermal conductivity 0.55 W/m and tissue density of 1050 kg/m3 . 2D breast model with realistic accuracy has been created, two tumors of 10 mm are inserted in the breast model, finite element method (FEM) is used for electrostatic and heat flow modeling of 2D breast model, with tumors. In this 2D modeling, convection and radiation boundary conditions are used for the measurement of heat flow, temperature in the tumors of the created 2D breast model [18]. Heat conduction in these tumors during the hyperthermia is observed. The primary purpose of this modeling is to get the heat flow inside tumor tissue using radiation Eq. 21 with integrated physics of tumor in realistic dimensions. This simulation, and modeling are carried out using COMSOL Multiphysics solver.

tumor regions, other surrounding tissues are in the safe temperature range (below 40°C). Figure 7 shows that temperature on the tumor site varies in the range of 42–44°C, and the heat flux density varies from 20.73 W/m2 to 31.89 W/m2 in the tumors. Our frequency is higher; hence it has limitations for the deep penetration in the tumors.

4 Conclusion This article concludes with successful results that, computational complexity has been reduced by iterative alternate direction implicit method, simulation results are in good agreement for numerical, analytical and 2D modeling of breast tumors. 2D modeling simulation results are showing efficient focusing of radio frequency waves on tumor sites of the breast model. The optimum distribution of heat flow density and temperature inside the tumor has also been demonstrated successfully. Hyperthermia treatment can be optimized concerning the heat application method and tumor site, to avoid hotspots on healthy tissues around the tumor. We have simulated, and modeled 2D breast model, for the HT’s accuracy, and stability of various treatment parameters in the HT. 3D modeling can also be done for different models of fatty, and dense fatty breast phantoms. Even these modeling results have scope of experimental validation in realistic environment.
