Agricultural production and operation produce a large amount of data, which hides valuable knowledge. Data mining technology can effectively explore the connection between various factors from the massive agricultural data. Classification prediction is one of the most valuable agricultural data mining techniques. This paper presents a new algorithm consisting of machine learning algorithms, feature ranking method and instance filter, which aims to enhance the capability of the random forest algorithm and better solve the problem of agricultural multi-class classification. The performance of the new algorithm was tested by using four standard agricultural multi-class datasets, and the experimental results showed that the newly proposed method performed well on all datasets. Among them, substantial rise in classification accuracy is observed for Eucalyptus dataset. Applying random forest algorithm on Eucalyptus dataset results in classification accuracy as 53.4% and after applying the new algorithm (rough set) the classification accuracy significantly increases to 83.7%.
农业生产经营产生大量的数据,这些数据中隐藏着有价值的知识。数据挖掘技术可以有效地从海量的农业数据中挖掘各种因素之间的联系。分类预测是最有价值的农业数据挖掘技术之一。为了提高随机森林算法的性能,更好地解决农业多类分类问题,本文提出了一种由机器学习算法、特征排序方法和实例滤波组成的新算法。利用4个标准农业多类数据集对新算法的性能进行了测试,实验结果表明,新算法在所有数据集上都具有良好的性能。其中,桉树数据集的分类精度显著提高。在Eucalyptus数据集上应用随机森林算法的分类准确率为53.4%,应用新算法(粗糙集)后,分类准确率显著提高到83.7%。

This research was conducted to perform an in-depth analysis of the coupling metrics of 10 Open Source Software (OSS) projects obtained from the Comets dataset. More precisely, we analyze the dataset of object-oriented OSS projects (having 17 code related metrics such as coupling, complexity, and size metrics) to (1) examine the relationships among the coupling and other metrics (size, complexity), (2) analyze the pattern in the growth of software metrics, and (3) propose a model for prediction of coupling. To generalize the model of coupling prediction, we have applied different machine learning algorithms and validated their performance on similar datasets. The results indicated that the Random forests algorithm outperforms all other models. The relation analysis specifies the existence of strong positive relationships between the coupling, size, and complexity metrics while the pattern analysis pinpointed the increasing growth trend for coupling. The obtained outcomes will help the developers, project managers, and stakeholders in better understating the state of software health
这项研究是为了对从comet数据集获得的10个开源软件(OSS)项目的耦合度量进行深入分析。更准确地说,我们分析了面向对象的OSS项目的数据集(有17个代码相关的度量,如耦合、复杂性和大小度量),以(1)检查耦合和其他度量(大小、复杂性)之间的关系,(2)分析软件度量增长中的模式,以及(3)提出耦合预测的模型。为了推广耦合预测模型,我们应用了不同的机器学习算法,并在相似的数据集上验证了它们的性能。结果表明,随机森林算法优于其他所有模型。关系分析指定了耦合、大小和复杂性度量之间存在强烈的正相关关系,而模式分析指出了耦合的增长趋势。获得的结果将帮助开发人员、项目经理和涉众更好地了解软件的健康状态

When Users Enjoy Using the System: The Case of AIS 当用户喜欢使用系统:以AIS为例
Pub Date : 2022-01-01 DOI: 10.4018/jitr.299952
E. Abu-Shanab, I. B. Salah
This study utilized an extended model of the Unified Theory of Acceptance and Use of Technology (UTAUT2) to explore the factors influencing the future adoption of accounting information systems (AIS) by Qatari students. A research model was proposed to predict future adoption, partially moderated by voluntary status of using the system. A sample of 237 students was used to probe their perceptions regarding the use of such systems in their future careers. Students were enrolled in an accounting information systems course in Qatar University. Results indicated that perceived facilitating conditions, performance expectancy and enjoyment were significant predictors of AIS. The other factors failed to be significant predictors. The estimated R2 was 48.4%. The moderation effect of voluntariness was also significant in influencing the relationship between enjoyment and future adoption. The moderator yielded a negative beta, which means that it faded the relationship under consideration. Conclusions and future recommendations are reported at the end of paper.

Soft Biometrics Authentication: A Cluster-Based Skin Color Classification System 软生物特征认证:基于聚类的肤色分类系统
Pub Date : 2022-01-01 DOI: 10.4018/jitr.298620
Abdou-Aziz Sobabe, Tahirou Djara, Blaise Blochaou, A. Vianou
This manuscript presents the design of a new approach of human skin color authentication. Skin color is one of the most popular soft biometric modalities. Since a soft biometric modality alone cannot reliably authenticate an individual, this new system is designed to combine skin color results with other pure biometric modalities to increase recognition performance. In the classification process, we first perform facial skin detection by segmentation using the thresholding method in the HSV color space. Then, the K-means algorithm of the clustering method is used to determine the dominant colors on the skin pixels in the RGB model. Variations according to the R, G and B components are recorded in a reference model to enable an individual’s identity to be predicted on the basis of 30 clusters. Experimental results are promising and give a false acceptance rate (FAR) of 29.47% and a false rejection rate (FRR) of 70.53%.
本文提出了一种新的人体肤色认证方法的设计。肤色是最流行的软生物识别模式之一。由于单靠软生物识别模式无法可靠地验证个人身份,因此该新系统将肤色结果与其他纯生物识别模式结合起来,以提高识别性能。在分类过程中,我们首先在HSV颜色空间中使用阈值分割方法进行面部皮肤检测。然后,使用聚类方法中的K-means算法确定RGB模型中皮肤像素上的主色。根据R, G和B组成部分的变化被记录在参考模型中,以便在30个集群的基础上预测个体的身份。实验结果表明,该方法的误接受率(FAR)为29.47%,误拒率(FRR)为70.53%。

Beall’s list heavily used as a base for selection of predatory journals by large no. of research studies was ceased from internet in 2017. Thus, status of journal declared as predatory in list is debatable. To verify quality of journals in terms of accuracy and standard of peer review, a sample of Medical Science journals from Beall list and indexed in reputed indexing/abstracting databases was taken. sample of journals was put to quality and credibility check by submitting a deliberately flawed research article. deliberate errors exceed an acceptable norm in submitted research paper. It is astonishing to see that majority of journals (61.96%) accept flawed article on such a sensitive issue, i.e., COVID-19 without peer review and desired revisions. Instant mails reporting paper's acceptance, preceded by multiple emails requesting for submission for Article processing fee, were received frequently. It is found that such publishing ventures are a scare story that only wants to generate as much revenue as possible.
Beall的名单被广泛用作选择掠夺性期刊的基础。一项研究于2017年从互联网上停止。因此,在列表中被声明为掠夺性期刊的地位是有争议的。为了从准确性和同行评议标准方面验证期刊的质量,从Beall列表中选取了医学科学期刊,并在知名索引/摘要数据库中检索。通过提交一篇故意有缺陷的研究文章,对期刊样本进行质量和可信度检查。在提交的研究论文中,故意的错误超过了可接受的标准。令人惊讶的是,对于COVID-19这样敏感的问题,大多数期刊(61.96%)在没有同行评审和期望修改的情况下接受了有缺陷的文章。报告论文被接受的即时邮件,以及之前要求提交文章处理费的多封电子邮件,经常收到。人们发现,这样的出版冒险是一个可怕的故事,只想产生尽可能多的收入。

Performance Enhancement of Cloud Datacenters Through Replicated Database Server 通过复制数据库服务器提高云数据中心的性能
Pub Date : 2022-01-01 DOI: 10.4018/jitr.299948
S. Patra, V. Goswami
Cloud computing has risen as a new computing paradigm providing computing, resources for networking and storage as a service across the network. Data replication is a phenomenon which brings the available and reliable data (e.g., maybe the databases) nearer to the consumers (e.g., cloud applications) to overcome the bottleneck and is becoming a suitable solution. In this paper, we study the performance characteristics of a replicated database in cloud computing data centres which improves QoS by reducing communication delays. We formulate a theoretical queueing model of the replicated system by considering the arrival process as Poisson distribution for both types of client request, such as read and write applications. We solve the proposed model with the help of the recursive method, and the relevant performance matrices are derived. The evaluated results from both the mathematical model and extensive simulations help to study the unveil performance and guide the cloud providers for modelling future data replication solutions.
云计算已经崛起为一种新的计算范式,为网络提供计算、资源和存储服务。数据复制是一种现象,它将可用的和可靠的数据(例如,可能是数据库)更接近消费者(例如,云应用程序),以克服瓶颈,并正在成为一种合适的解决方案。在本文中,我们研究了云计算数据中心中复制数据库的性能特征,通过减少通信延迟来提高QoS。通过考虑两种类型的客户端请求(如读和写应用)的到达过程为泊松分布,我们建立了复制系统的理论排队模型。利用递归方法对模型进行求解,并推导出相应的性能矩阵。来自数学模型和广泛模拟的评估结果有助于研究揭开性能,并指导云提供商为未来的数据复制解决方案建模。

Detection of abnormal crowd behavior is one of the important tasks in real-time video surveillance systems for public safety in public places such as subway, shopping malls, sport complexes and various other public gatherings. Due to high density crowded scenes, the detection of crowd behavior becomes a tedious task. Hence, crowd behavior analysis becomes a hot topic of research and requires an approach with higher rate of detection. In this work, the focus is on the crowd management and present an end-to-end model for crowd behavior analysis. A feature extraction-based model using contrast, entropy, homogeneity, and uniformity features to determine the threshold on normal and abnormal activity has been proposed in this paper. The crowd behavior analysis is measured in terms of receiver operating characteristic curve (ROC) & area under curve (AUC) for UMN dataset for the proposed model and compared with other crowd analysis methods in literature to prove its worthiness. YouTube video sequences also used for anomaly detection.
人群异常行为检测是地铁、商场、体育场馆等公共场所公共安全实时视频监控系统的重要任务之一。由于高密度的拥挤场景,人群行为的检测成为一项繁琐的任务。因此,群体行为分析成为研究的热点,对检测率更高的方法提出了更高的要求。在这项工作中,重点关注人群管理,并提出了一个端到端的人群行为分析模型。本文提出了一种基于特征提取的模型,利用对比度、熵、均匀性和均匀性特征来确定正常和异常活动的阈值。针对所提出的模型,用UMN数据集的受试者工作特征曲线(ROC)和曲线下面积(AUC)来测量人群行为分析,并与文献中其他人群分析方法进行比较,以证明其价值。YouTube视频序列也用于异常检测。

Traditional agriculture is facing numerous serious issues such as climate variation, population rise, water scarcity, soil degradation, and food security and many more. Though, Aquaponics is a promising solution, research on building an economically feasible smart Aquaponics system is still a challenge. In this paper, a sustainable smart Aquaponics system using Internet of Things (IOT) and Data Analytics is proposed. The acquired data from sensors such as Ph sensor, and temperature sensor, is analyzed using machine learning techniques to interpret the health of the system. Further, the proposed system includes automated fish feeder which is controlled by Raspberry Pi to automate and reduce the maintenance issues. The android application helps the user to remotely control and monitor the health of the system and also track the critical system parameters. Further the system is driven by the solar power to make it sustainable. A comprehensive survey on the key aspects of Aquaponics including comparison of the proposed model with the traditional aquaponics model is also presented.

The android application helps the user to remotely control and monitor the health of the system and also track the critical system parameters. Further the system is driven by the solar power to make it sustainable. A comprehensive survey on the key aspects of Aquaponics including comparison of the proposed model with the traditional aquaponics model is also presented.","PeriodicalId":296080,"journal":{"name":"J.

The stock market volume and price are an active area of research for the past many years. Behind every dollar of investment, the customer will be hoping for profit in one or the other way. There is a positive correlation between investor sentiment and stock volume. Predicting the stock market is the most difficult task due to the dynamic fluctuation of volume and price. The traditional analysis methods carried out leads to satisfactory results. In this paper, the proposed system uses real-time data from Twitter to detect the user opinion about the product along with the stock volume for prediction. The stock volume data and the Twitter data are collected first and then the classification of the polarity is carried out using the SentiWordnet dictionary. The algorithm for the prediction of the stock prices uses Long-short term memory, a neural network as the prices are sequential evolving in nature. The results of the proposed system are correlated between the stock market and Twitter data to obtain better insights that are positive.
股票市场的数量和价格是一个活跃的研究领域,在过去的许多年。在每一美元投资的背后,客户都希望以这样或那样的方式获利。投资者情绪与股票成交量呈正相关关系。由于成交量和价格的动态波动,预测股票市场是最困难的任务。传统的分析方法得到了满意的结果。在本文中,提出的系统使用来自Twitter的实时数据来检测用户对产品的意见以及进行预测的库存量。首先收集存量数据和Twitter数据,然后使用SentiWordnet字典进行极性分类。股票价格的预测算法使用了长短期记忆,这是一种神经网络,因为价格在本质上是顺序演变的。该系统的结果在股票市场和Twitter数据之间进行关联,以获得更好的正面见解。
