Abstract Currently, Arabic character recognition remains one of the most complicated challenges in image processing and character identification. Many algorithms exist in neural networks, and one of the most interesting algorithms is called generative adversarial networks (GANs), where 2 neural networks fight against one another. A generative adversarial network has been successfully implemented in unsupervised learning and it led to outstanding achievements. Furthermore, this discriminator is used as a classifier in most generative adversarial networks by employing the binary sigmoid cross-entropy loss function. This research proposes employing sigmoid cross-entropy to recognize Arabic handwritten characters using multi-class GANs training algorithms. The proposed approach is evaluated on a dataset of 16800 Arabic handwritten characters. When compared to other approaches, the experimental results indicate that the multi-class GANs approach performed well in terms of recognizing Arabic handwritten characters as it is 99.7% accurate. Keywords: Generative Adversarial Networks (GANs), Arabic Characters, Optical Character Recognition, Convolutional Neural Networks (CNNs).
摘要当前,阿拉伯语字符识别仍然是图像处理和字符识别中最复杂的挑战之一。神经网络中存在许多算法,其中最有趣的算法之一被称为生成对抗性网络(GANs),其中两个神经网络相互对抗。生成对抗性网络在无监督学习中得到了成功的实现,并取得了突出的成就。此外,该鉴别器通过使用二进制S形交叉熵损失函数,被用作大多数生成对抗性网络中的分类器。本研究提出利用S形交叉熵,利用多类GANs训练算法对阿拉伯手写体字符进行识别。在16800个阿拉伯手写字符的数据集上对所提出的方法进行了评估。与其他方法相比,实验结果表明,多类GANs方法在识别阿拉伯手写字符方面表现良好,准确率为99.7%。关键词:生成对抗性网络,阿拉伯文字,光学字符识别,卷积神经网络。

Abstract Data mining techniques have recently drawn considerable attention from the research community for their ability to predict flash flood phenomena. These techniques can bring large-scale flood data into real practice and have become the necessary tools for impact assessment, societal resilience, and disaster control. Although numerous studies have been conducted on data mining techniques and flash flood predictions, domain-specific flash flood prediction models based on existing data mining techniques are still lacking. Notably, this study has focused on the performance of four data mining techniques, namely, logistic regression (LR), artificial neural networks (ANN), k-nearest neighbour (kNN), and support vector machine (SVM) in a comparative assessment as prediction models. The area under the curve (AUC) was utilised to validate these models. The value of AUC was higher than 0.9 for all models. Accordingly, the outcomes outlined in this study can contribute to Halim et al. the current literature by boosting the performance of data mining techniques for predicting flash floods through a comparison of the most recent data mining techniques. Keywords: Artificial neural networks (ANN), Flash flood, k-nearest neighbor (kNN), Logistic regression (LR), Support vector machine (SVM)
摘要数据挖掘技术最近因其预测山洪现象的能力而引起了研究界的极大关注。这些技术可以将大规模的洪水数据付诸实践,并已成为影响评估、社会复原力和灾害控制的必要工具。尽管已经对数据挖掘技术和山洪预测进行了大量研究,但基于现有数据挖掘技术的特定领域山洪预测模型仍然缺乏。值得注意的是,本研究重点研究了四种数据挖掘技术的性能,即逻辑回归(LR)、人工神经网络(ANN)、k近邻(kNN)和支持向量机(SVM)作为预测模型在比较评估中的性能。曲线下面积(AUC)用于验证这些模型。所有模型的AUC值均高于0.9。因此,本研究中概述的结果可以通过比较最新的数据挖掘技术来提高数据挖掘技术预测山洪暴发的性能,从而为Halim等人的当前文献做出贡献。关键词:人工神经网络(ANN)、山洪暴发、k近邻(kNN)、逻辑回归(LR)、支持向量机(SVM)

Abstract Since the early days of 2020, COVID-19 has tragic effects on the lives of human beings all over the world. To combat this disease, it is important to survey the infected patients in an inexpensive and fast way. One of the most common ways of achieving this is by performing radiological testing using chest X-Rays and patient coughing sounds. In this work, we propose a Convolutional Neural Network-based solution which is able to identify the positive COVID-19 patients using chest XRay images. Multiple CNN models have been adopted in our work. Each of these models provides a decision whether the patient is affected with COVID-19 or not. Then, a weighted average selection technique is used to provide the final decision. To test the efficiency of our model we have used publicly available chest X-ray images of COVID positive and negative cases. Our approach provided a classification performance of 88.5%. Keywords: COVID-19, CT-Images, Deep Learning, CNN Algorithm.
摘要自2020年初以来,新冠肺炎给世界各地的人类生活带来了悲惨的影响。为了对抗这种疾病,以一种廉价而快速的方式对感染患者进行调查是很重要的。实现这一点的最常见方法之一是使用胸部X射线和患者咳嗽声进行放射学测试。在这项工作中,我们提出了一种基于卷积神经网络的解决方案,该解决方案能够使用胸部XRay图像识别新冠肺炎阳性患者。在我们的工作中采用了多种CNN模型。这些模型中的每一个都提供了患者是否受新冠肺炎影响的决定。然后,使用加权平均选择技术来提供最终决策。为了测试我们模型的效率,我们使用了公开的新冠肺炎阳性和阴性病例的胸部X光图像。我们的方法提供了88.5%的分类性能。关键词:新冠肺炎,CT图像,深度学习,CNN算法。

Abstract The real estate market is one of the most impacted sectors from the Corona Virus Disease 2019 (COVID-19) pandemic that happened in early 2020 globally. Here, we tried to apply an extension of the Long Short-Term Memory (LSTM) deep learning method, known as the Bidirectional LSTM (Bi-LSTM) networks for stock price prediction. Our focus is on six stocks that were included in the LiQuid45 (LQ45) property and real estate sectors. A simple three-layers Bi-LSTM network is proposed for predicting the stocks’ closing prices. We found that the prediction results fall in the reasonable prediction category, except for Pembangunan Perumahan Tbk (PTPP). Bumi Serpong Damai Tbk (BSDE) got the highest accuracy result with more than 90% score, while PTPP got the lowest score with less than 8% score. The proposed Bi-LSTM network could provide a baseline result for developing a good trading strategy. Keywords: Bi-LSTM networks, deep learning, LQ45, property and real estate, stock price prediction.

Abstract Prediction of gene-drug-disease interactions have talented new insights in biology. Discovering unknown interactions will provide new therapeutic approaches to explore gene expressions. Recent improvements in machine learning techniques have gotten considerable interest due to higher efficiency, accurate results, and their lower cost. However, most of the studies were ignoring relevant associations, by representing only drug-disease interactions on a network while public available data offers a large variety of interactions. Additionally, some computational techniques used in this domain are faced with new challenges, related to the organization of heterogeneous data which suffer from a high imbalance rate since there are extensively more non-interacting gene-drug-disease triplets than interacting ones. In this paper we present integration of heterogeneous biological data about genes, drugs, and diseases to build a model, and building a new graph representation relating genedrug-disease interactions. Using extreme gradient boosting (XGBoost) algorithm, we have been able to extract a list of valid interactions about gene-drug-disease triplets, and a list of gene-drug pairs related to lung cancer. Keywords: Biological heterogeneous data, Data integration, Gene-DrugDisease interactions, Machine learning.
摘要基因-药物-疾病相互作用的预测在生物学中有着新的见解。发现未知的相互作用将为探索基因表达提供新的治疗方法。最近机器学习技术的改进由于其更高的效率、准确的结果和更低的成本而引起了人们的极大兴趣。然而,大多数研究都忽略了相关关联,只在网络上表示药物与疾病的相互作用,而公共可用数据提供了各种各样的相互作用。此外,该领域中使用的一些计算技术面临着新的挑战,涉及异构数据的组织,这些数据具有高不平衡率,因为非相互作用的基因-药物-疾病三联体比相互作用的三联体多得多。在本文中,我们提出了关于基因、药物和疾病的异质生物学数据的集成,以建立一个模型,并建立一个新的与基因-药物-疾病相互作用相关的图表示。使用极限梯度增强(XGBoost)算法,我们已经能够提取关于基因-细菌-三重态的有效相互作用列表,以及与癌症相关的基因-细菌对列表。关键词:生物异构数据,数据集成,基因-药物-疾病相互作用,机器学习。

Human identification using finger knuckle features 利用指关节特征进行人体识别
Q3 Computer Science Pub Date : 2022-03-28 DOI: 10.15849/ijasca.220328.07

Abstract Many studies refer that the figure knuckle comprises unique features. Therefore, it can be utilized in a biometric system to distinguishing between the peoples. In this paper, a combined global and local features technique has been proposed based on two descriptors, namely: Chebyshev Fourier moments (CHFMs) and Scale Invariant Feature Transform (SIFT) descriptors. The CHFMs descriptor is used to gaining the global features, while the scale invariant feature transform descriptor is utilized to extract local features. Each one of these descriptors has its advantages; therefore, combining them together leads to produce distinct features. Many experiments have been carried out using IIT-Delhi knuckle database to assess the accuracy of the proposed approach. The analysis of the results of these extensive experiments implies that the suggested technique has gained 98% accuracy rate. Furthermore, the robustness against the noise has been evaluated. The results of these experiments lead to concluding that the proposed technique is robust against the noise variation. Keywords: finger knuckle, biometric system, Chebyshev Fourier moments, scale invariant feature transform, IIT-Delhi knuckle database.
摘要许多研究认为指关节具有独特的特征。因此,它可以用于生物识别系统来区分人群。本文提出了一种基于切比雪夫傅里叶矩(CHFMs)和尺度不变特征变换(SIFT)两种描述子的全局特征和局部特征相结合的方法。CHFMs描述子用于获取全局特征,尺度不变特征变换描述子用于提取局部特征。每种描述符都有其优点;因此,将它们结合在一起会产生不同的特征。使用IIT-Delhi关节数据库进行了许多实验,以评估所提出方法的准确性。对大量实验结果的分析表明,该方法的准确率达到了98%。此外,还评估了该方法对噪声的鲁棒性。实验结果表明,该方法对噪声变化具有较强的鲁棒性。关键词:指关节,生物识别系统,切比雪夫傅立叶矩,尺度不变特征变换,IIT-Delhi指关节数据库。

Abstract Humans have been fighting the Covid19 pandemic since it started, not just to protect their wellbeing but also to counteract the news and rumors that have been spreading about it. Rumors and false allegations can be almost as dangerous as the virus, as they affect people's mental health and increase their stress levels. To address this problem, several machine learning techniques could be used to detect fake news. In this paper, four different machine learning algorithms are compared according to their ability to detect fake news, including Naive Bayes, Decision Tree, Support Vector Machines, and Logistic Regression. A dataset of annotated news is used in the experiments. The experimental results show that Naïve Bayes outperforms other algorithms in terms of accuracy, precision, recall, and F1 score. Keywords: COVID-19, Machine Learning, Fake news detection.
自covid - 19大流行开始以来,人类一直在与之抗争,不仅是为了保护自己的健康,也是为了抵消有关它的新闻和谣言。谣言和虚假指控几乎和病毒一样危险,因为它们会影响人们的心理健康,增加他们的压力水平。为了解决这个问题,可以使用几种机器学习技术来检测假新闻。在本文中,根据检测假新闻的能力,比较了四种不同的机器学习算法,包括朴素贝叶斯,决策树,支持向量机和逻辑回归。实验中使用了一个带注释的新闻数据集。实验结果表明Naïve Bayes在准确率、精密度、召回率和F1分数方面都优于其他算法。关键词:COVID-19,机器学习,假新闻检测

Abstract The various model that has been used to predict, datamining, and information retrieval are useful to use through the traditional database, due to big data the prediction should derive in a different role that conduct the hidden structure data based on a stability scale to allow discovering accrue unsupervised drug data. Especially, the drug data must be understandable to analysts. Following this approach, conduct the stability drug data through computation methods are quality measurements, preprocess data, k-mean cluster, and decision tree. This approach seeks to identify the data by two dimensions (vertically and horizontally), which extrapolations, compilation, and interpretation values of the dataset while considering individual attributes. A comparison with clusters defines the set for features using balance value by K-mean algorithm to determine the k clusters that consider the set of features based on two values 0 and 1, which given the discernible between dependent and independent class target, and pinpoint the relationship among them.

摘要用于预测、数据挖掘和信息检索的各种模型都是通过传统的数据库来使用的,由于大数据的存在,预测需要在不同的角色中派生,即基于稳定尺度对隐藏结构数据进行挖掘,以允许发现累积的无监督药物数据。特别是,药物数据必须是分析师可以理解的。根据该方法,通过质量测量、预处理数据、k-均值聚类和决策树等计算方法对药物数据进行稳定性分析。这种方法试图通过两个维度(垂直和水平)来识别数据,这两个维度在考虑单个属性的同时推断、编译和解释数据集的值。与聚类的比较,通过k -mean算法使用平衡值定义特征集,确定k个聚类,考虑基于两个值0和1的特征集,给定依赖和独立类目标之间的可辨性,并确定它们之间的关系。关键词:大数据,离散化,k-均值聚类稳定性,靶向药物
