Sentiment analysis refers to the active field of Natural language processing that extracts the attitude and emotion of a human being. With the growth of social media, more people are using online platforms such as Twitter, Facebook, Y ouTube, etc. to express their opinions. Twitter is considered to be the purest platform to express one's views. Mostly all personalities from diverse backgrounds use twitter. Therefore, it becomes a need of the hour to study public opinion. This provides us valuable information and helps organizations and governments to contemplate mass public opinion and take better decisions accordingly. In this review paper, an extensive and exhaustive guide to the subfield of Natural language processing (NLP), focusing precisely on sentiment analysis on twitter dataset, has been presented. It highlights three main approaches to analyze the sentiment. We have summarized and compared the approaches on different metrics opted by various researchers in the field of sentiment analysis using the twitter dataset. With so much active work in this field, this review paper would assist all future researchers.

A collection of sensor nodes are available in wireless sensor network for gathering the distinguish data from environment. This sensing process consumes more energy of the network which effects the whole network life time. So energy usage in efficient manner is the main issue to maintaining the network. Clustering is the process used for reducing the energy consumption. K-means is the post popular clustering algorithm to form the clusters. In this paper, propose energy efficient clustering i.e quad clustering based on K-means algorithm. This approach improves the performance of wireless sensor network in terms of network lifetime. As simulation shows the proposed work is better than single cluster in case of distance coverage as well as energy consumption.
在无线传感器网络中,有一组传感器节点用于采集环境识别数据。这种感知过程会消耗更多的网络能量,影响整个网络的生命周期。因此,有效地利用能源是维护电网的主要问题。聚类是用于降低能耗的过程。K-means是后流行的聚类算法。本文提出了一种基于K-means算法的高效聚类方法,即四元聚类。这种方法在网络寿命方面提高了无线传感器网络的性能。仿真结果表明,在距离覆盖和能耗方面,该算法优于单簇算法。

Crop diseases are a major cause of degrading the quality and reducing the number of agricultural products. Hence, there is a strong need for the early diagnosis of the disease. The effectiveness of deep learning techniques in pattern matching and image processing motivated the authors to design an automatic tool for the detection of diseases in bell pepper plants. In this manuscript, the authors present the comparative analysis of different deep learning models applied for plant disease classification. They applied the deep learning models namely VGG16, VGG19, ResNet50, ResNet101, ResNet152, InceptionResNetV2, DenseNet121 on the publicly available dataset of the bell pepper plant. The experimental results prove that the model ‘DenseNet’ requires less training time and gives the highest validation accuracy among all the above-stated models. It achieves a training accuracy of 97.49% and the testing accuracy of 96.87% in classifying the bell pepper plants into healthy and diseased categories.

Lately the trend of the internet is taking a front seat for different applications. Organizations are collecting and processing and then sharing the data using the internet. Sharing using public network will invite various security lapses in the data. Security will remain the maj or thrust in the area for providing enough level of security for the data. Encryption is the best way to provide security for the data. There are two different types of approaches for ensuring data security. These techniques are symmetric and asymmetric. The symmetric technique includes different approaches with variation in the time and space complexity. In this research paper five different techniques of the symmetric approaches are compared for three different length strings. AES is the best performing in all the three cases. The time comparison for the AES with different techniques is comparatively better than the other four techniques like IDEA, RC6, Two Fish, MARS.

A* algorithm performs well as a Best First Search method, which would not give the shortest path in certain scenarios. Its accuracy depends on the heuristic function and has slow processing speed in the real world. RRT performs slower than A* and Dijkstra's algorithm gives correct output but shows us a slow runtime performance unsuitable for the real-world. This paper uses Dijkstra's algorithm using the priority queue for testing and proposes an approach that can be applied to any path planning algorithm. Experimental results show that the proposed approach performs 51% faster than A* on game datasets and 14% faster on extremely dense map datasets.
A*算法作为最佳优先搜索方法表现良好,但在某些情况下不会给出最短路径。其精度依赖于启发式函数,在现实世界中处理速度较慢。RRT的执行速度比A*慢,Dijkstra的算法给出了正确的输出,但向我们展示了不适合现实世界的缓慢运行时性能。本文采用Dijkstra算法使用优先级队列进行测试,并提出了一种适用于任何路径规划算法的方法。实验结果表明,该方法在游戏数据集上的速度比A*快51%,在极密集地图数据集上的速度比A*快14%。

Today healthcare industries are maintaining COVID-19 patients' information electronically which includes patients' diagnostic reports, patients' private information, and doctor prescriptions. However, the COVID-19, patient sensitive information is currently stored in centralized or third-party storage model. One of the key challenge of centralized storage model is the preserving privacy of patient information and transparency in the system. The privacy risk include illegitimate access to sensitive information of patient such as identification details access and misutilization of patient information and their clinical records. To overcome this challenge, we proposed a distributed on-chain and off-chain storage model using consortium blockchain and interplanetary file systems (IPFS). The proposed framework though maintaining patient privacy makes it easier for legitimate entities like healthcare providers (e.g., physicians and clinical staffs) to access clinical data of COVID-19 patients'.
如今,医疗保健行业正在以电子方式维护COVID-19患者的信息,包括患者的诊断报告、患者的私人信息和医生的处方。但是,COVID-19患者的敏感信息目前存储在集中式或第三方存储模式中。集中存储模式面临的主要挑战之一是保持患者信息的隐私性和系统的透明度。隐私风险包括非法访问患者身份信息等敏感信息,访问和滥用患者信息及其临床记录。为了克服这一挑战,我们提出了一种使用联盟区块链和星际文件系统(IPFS)的分布式链上和链下存储模型。拟议的框架虽然维护了患者的隐私,但使医疗保健提供者(例如医生和临床工作人员)等合法实体更容易访问COVID-19患者的临床数据。

The article aims to investigate the effect of shifting of spectral reflectance on colorimetric parameters due to solar exposure of the commercially available artificial fabric-based vegetation. The spectral reflectance of the control (samples at time t0) and exposed samples (time t0+t) are measured and analyzed in the visible region using a spectrophotometer. The CIE XYZ color coordinates are computed from the measured spectral reflectance. The XYZ represents the area under the multiplied spectral reflectance, illuminant and observer function. The XYZ parameters are computed for D65 illuminant and 10o observer function. The change in the XYZ with wavelength is discussed to correlate the deviation of the XYZ with color fading. The L*a*b and sRGB values are derived from the XYZ to visualize the color change. The work finds a range of applications in color based process automation, object discrimination and remote sensing for change analysis.

Most common cancer in females is found to be Breast cancer which is a widespread disease. One out of eight females worldwide are affected by this cancer only. We can detect this cancer by detecting malignancy from breast tissues. There are various types of computer-aided techniques and approaches which are used by doctors for detecting cancer. The major objective of this paper is to build a well-defined model for the recognition of breast cancer by expending various parameters. Different types of machine learning and deep learning methodologies are used for the classification of malignant and benign tissues. In this we are using a dataset that obtains 569 samples with 30 features, this dataset is majorly called the Wisconsin dataset. Many techniques are implemented on this dataset we are using deep convolutional neural network (CNN) and Machine learning methodology (KNN) for the diagnosis and training purpose and then compare the results of both the techniques. Deep convolutional NN is implemented on the google platform called the Google Colab on the other side KNN is implemented on the Anaconda Spyder platform. The best accuracy achieved from KNN is 96.49%. To improve the performance and accuracy we implemented CNN on the same dataset and then achieved 99.41% accuracy. Deep learning is extensively useful in getting the best and optimal results in other performance matrics such as precision, recall, F1-score and AVC-ROC - 98.64%,97.61 %, 98.08%, 97.61% respectively.
女性中最常见的癌症是乳腺癌,这是一种广泛存在的疾病。全世界每八个女性中就有一个患有这种癌症。我们可以通过检测乳腺组织的恶性肿瘤来检测这种癌症。医生们使用了各种各样的计算机辅助技术和方法来检测癌症。本文的主要目的是通过扩展各种参数来建立一个定义良好的乳腺癌识别模型。不同类型的机器学习和深度学习方法用于恶性和良性组织的分类。在这里,我们使用一个数据集,它获得了569个样本和30个特征,这个数据集主要被称为威斯康星数据集。在这个数据集上实现了许多技术,我们使用深度卷积神经网络(CNN)和机器学习方法(KNN)进行诊断和训练,然后比较这两种技术的结果。深度卷积神经网络是在谷歌的Colab平台上实现的,而KNN是在Anaconda Spyder平台上实现的。KNN的最佳准确率为96.49%。为了提高性能和准确率,我们在相同的数据集上实现了CNN,准确率达到了99.41%。深度学习在精度、召回率、f1分数和AVC-ROC(分别为98.64%、97.61%、98.08%、97.61%)等其他性能指标上获得最佳和最优结果方面有着广泛的应用。

Deep convolutional NN is implemented on the google platform called the Google Colab on the other side KNN is implemented on the Anaconda Spyder platform. The best accuracy achieved from KNN is 96.49%. To improve the performance and accuracy we implemented CNN on the same dataset and then achieved 99.41% accuracy. Deep learning is extensively useful in getting the best and optimal results in other performance matrics such as precision, recall, F1-score and AVC-ROC - 98.64%,97.61 %, 98.08%, 97.61% respectively.","PeriodicalId":347216,"journal":{"name":"2020 Sixth International Conference on Parallel, Distributed and Grid Computing (PDGC)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114373337","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Cricket is one of the most watched sports in the world. Analyzing the factors, activities that affect the aftermath of the matches is of interest to many cricket lovers. Machine learning (ML) has demonstrated favorable outcomes in various fields like medical diagnosis, image processing, prediction, classification, regression etc. and is evidenced to be accurate. The ingenious frameworks built on ML have scope to learn from past experiences. The cricket pitch is the prime segment along with home game advantage, coin toss, innings, day/night match, physical fitness etc. A compendious examination of the cricket pitch, if done with imminent objectives, will be useful to precisely speculate outcomes match. This paper focuses on the existing research for analyzing the cricket pitch, predicting the performance of players and outcomes of the matches. A comparison among machine learning techniques has also been done and Naïve Bayes gave the best results due to its capability of producing accurate results with small samples while in other researches random forest turned out to be the precise classifier as it gave more accuracy than any other approach used.
板球是世界上最受关注的运动之一。分析影响比赛后果的因素和活动是许多板球爱好者感兴趣的。机器学习(ML)在医学诊断、图像处理、预测、分类、回归等各个领域都显示出良好的效果,并被证明是准确的。基于机器学习的巧妙框架可以从过去的经验中学习。板球场是主要的部分,还有主场比赛优势、抛硬币、一局、日夜比赛、体能等。对板球场进行一次简明的检查,如果是针对迫在眉睫的目标,将有助于精确地推测比赛结果。本文对已有的板球球场分析、球员表现预测和比赛结果预测研究进行了综述。机器学习技术之间的比较也已经完成,Naïve贝叶斯给出了最好的结果,因为它能够用小样本产生准确的结果,而在其他研究中,随机森林被证明是精确的分类器,因为它比使用的任何其他方法都更准确。
