Study and Analysis of Data Analysis Systems (Reconstruction of a Learning Data from the Initial Data) 数据分析系统的研究与分析(从初始数据重构一个学习数据)
S. Belattar, O. Abdoun, Haimoudi El Khatir
Data analysis methods have been widely used in various domains, such as medical, marketing, and agriculture. Since they have a good performance to reduce massive data. Unfortunately, those methods are limited without the usage of Computer Technologies (computer technologies, 'CT'), which lead to developing autonomous systems capable of making appropriate decisions in each situation, by the realization of algorithm and artificial intelligence (artificial intelligence, 'AI') tools. This paper presents the coupling of principal component analysis (principal component analysis, 'PCA') mathematical method and the counter propagation artificial neural network (counter propagation network, 'CPN'), as an objective to reduce and minimize the data before starting learning, improve the learning process results and accuracy of the classification and eliminate the obstacles detected between inputs objects. The results of this combination have been compared with the results of the standard CPN.

Machine Learning Aprroach for Early Detection of Glaucoma from Visual Fields 从视野中早期检测青光眼的机器学习方法
Stéphane Cédric KOUMETIO TEKOUABOU, E. A. Alaoui, I. Chabbar, Walid Cherif, H. Silkan
Glaucoma is one of the leading causes of blindness and visual impairment in adults and the elderly. Early detection of this disease through regular screening is particularly important in preventing vision loss. To do this, several diagnostic techniques are used ranging from classical techniques centered on an expert to modern diagnostic methods, sometimes completely computerized. The implementation of computerized systems based on the early detection and classification of clinical signs of glaucoma can greatly improve the diagnosis of this disease. Several authors have proposed models allowing the automatic classification of clinical signs of glaucoma. However, not only these models are not efficient enough and remain optimizable but also often do not take into account the problem of data instability in their construction and the performance test measures adapted to evaluate them. In this paper, a predictive model based on the Support Vector Machine (SVM) has been introduced to optimize the automated diagnosis of glaucoma signs using patient visual field data. A comparative study of performance as a function of the parameters of this algorithm, which is particularly effective for this type of problem, has been made. The best results for the data collected at the Glaucoma Center of Semmelweis University in Budapest have proven to significantly improve the performance of the models offered so far especially in terms of precision, accuracy and AUC while reducing execution time.
青光眼是导致成人和老年人失明和视力损害的主要原因之一。通过定期筛查及早发现这种疾病对预防视力丧失尤为重要。为了做到这一点,使用了几种诊断技术,从以专家为中心的经典技术到现代诊断方法,有时完全计算机化。基于青光眼临床症状的早期发现和分类的计算机化系统的实施可以大大提高该病的诊断。几位作者提出了允许青光眼临床症状自动分类的模型。然而,这些模型不仅效率不够高,而且仍然是可优化的,而且在其构建过程中往往没有考虑数据不稳定的问题以及用于评估它们的性能测试措施。本文提出了一种基于支持向量机(SVM)的预测模型,利用患者视野数据优化青光眼体征的自动诊断。对该算法的性能作为参数的函数进行了比较研究,该算法对这类问题特别有效。布达佩斯Semmelweis大学青光眼中心收集的数据的最佳结果已被证明可以显着提高迄今为止提供的模型的性能,特别是在精度,准确度和AUC方面,同时减少了执行时间。

Unified Process to Design and Develop Serious Games for Schoolchildren 学童严肃游戏设计与开发的统一过程
Younès Alaoui, Amine Belahbib, Lotfi El Achaak, M. Bouhorma
Serious Games start playing an important role in education [8]. Developed economies start using serious games for a variety of objectives among whish we find retraining the workforce, offering off-hours training in self-service mode, supplementing teachers work with games appealing to young generations, and reducing training costs [6], [7]. Learning in these developed economies is based usually on active methods and serious games bring additional training activities to the learning process[14][15]. Learning in some developing countries is based on remembering and reciting mainly. Training schoolchildren on applying knowledge is a challenge for teachers in some developing countries. Developing countries can use serious games as a catalyst to train schoolchildren on applying knowledge. The development of such serious games for schoolchildren requires collaboration between pedagogues, game designers and software developers. In this paper, we present a process and a methodology to design and develop serious games for schoolchildren. This process is called Gaming and Learning Unified Process to engineer Software, or GLUPS. We present the foundations of GLUPS, list its main artifacts, and illustrate this paper with the application of GLUPS to design a serious game that train on applying the Euclidean Division.
严肃游戏开始在教育中扮演重要角色[8]。发达经济体开始将严肃游戏用于各种目标,我们发现其中包括劳动力再培训,以自助模式提供非工作时间培训,以吸引年轻一代的游戏补充教师工作,以及降低培训成本[6],[7]。在这些发达经济体中,学习通常以积极的方法为基础,严肃的游戏为学习过程带来了额外的训练活动[14][15]。在一些发展中国家,学习主要是基于记忆和背诵。在一些发展中国家,培训学童应用知识是教师面临的一项挑战。发展中国家可以利用严肃游戏作为一种催化剂,训练学童应用知识。为学生开发这种严肃游戏需要教师、游戏设计师和软件开发者之间的合作。在本文中,我们提出了设计和开发面向学童的严肃游戏的过程和方法。这个过程被称为设计软件的游戏和学习统一过程(GLUPS)。我们介绍了GLUPS的基础,列出了它的主要产物,并通过GLUPS设计一个训练应用欧几里得除法的严肃游戏来说明本文。

Abdelhamid Riadi, M. Boulouird, M. Hassani
Massive-Multiple Input Multiple Output (M-MIMO) is a new technology offers large antenna at the Base Station (BS), simultaneously serving multiple single-antenna users. In this paper, two geometrical channels are established and compared, based on Plane Wave (PW) and Spherical Wave (SW). The Multipolarized-Uniform-Linear-Array Massive-MIMO (MULA-mMIMO) and Multipolarized-Uniform-Circular-Array Massive-MIMO (MUCA-mMIMO) systems are used to decrease the channel orthogonality. The three dimensional MUCA-mMIMO and MULA-mMIMO are evaluated and analyzed for various parameters. Simulation results demonstrate that MUCA-mMIMO performs better than MULA-mMIMO, and will be the best choice for the new technology Massive-MIMO.

Nowadays training of specialists for different branches of national economy acquires more significance than 20-25 years ago. As in other branches of economy, the same competition is met in an educational system in a marketplace. The main reason of it is globalization and general development of production technology and service in developed countries. It should be noted that in conditions of globalization of economy the competition envelopes not only the marketplace, but also the production process itself. The purpose of the work is investigation of problems of improving education system in conditions of severe competition and possibility of applying of REENGINEERING in revealing of a number of priority factors of success.
如今,培养国民经济各部门的专家比20-25年前更加重要。与其他经济部门一样,市场上的教育系统也面临着同样的竞争。其主要原因是全球化和发达国家生产技术和服务的普遍发展。应该指出,在经济全球化条件下,竞争不仅包括市场,而且包括生产过程本身。这项工作的目的是调查在激烈竞争条件下改善教育制度的问题,以及应用再造工程揭示一些成功的优先因素的可能性。

A Smart Chatbot Architecture based NLP and Machine Learning for Health Care Assistance 基于NLP和机器学习的智能聊天机器人体系结构的医疗辅助
Soufyane Ayanouz, Boudhir Anouar Abdelhakim, M. Benahmed
A chatbot or conversational agent is a software that can communicate with a human by using natural language. One of the essential tasks in artificial intelligence and natural language processing is the modeling of conversation. Since the beginning of artificial intelligence, its been the hardest challenge to create a good chatbot. Although chatbots can perform many tasks, the primary function they have to play is to understand the utterances of humans and to respond to them appropriately. In the past, simple statistic methods or handwritten templates and rules were used for the constructions of chatbot architectures. With the increasing learning capabilities, end-to-end neural networks have taken the place of these models in around 2015. Especially now, the encoder-decoder recurrent model is dominant in the modeling of conversations. This architecture is taken from the neural machine translation domain, and it performed very well there. Until now, plenty of features and variations are introduced that have remarkably enhanced the conversational capabilities of chatbots. In this paper, we performed a detailed survey on recent literature. We examined many publications from the last five years, which are related to chatbots. Then we presented different related works to our subject, and the AI concepts needed to build an intelligent conversational agent based on deep learning models Finally, we presented a functional architecture that we propose to build an intelligent chatbot for health care assistance.
聊天机器人或会话代理是一种可以使用自然语言与人类交流的软件。人工智能和自然语言处理的基本任务之一是会话建模。自人工智能出现以来,创造一个好的聊天机器人一直是最大的挑战。虽然聊天机器人可以执行许多任务,但它们必须发挥的主要功能是理解人类的话语并对其做出适当的反应。在过去,简单的统计方法或手写的模板和规则被用于聊天机器人架构的构建。随着学习能力的提高,端到端神经网络在2015年左右取代了这些模型。特别是现在,编码器-解码器循环模型在会话建模中占主导地位。该体系结构来源于神经机器翻译领域,在该领域表现良好。到目前为止,已经引入了大量的特性和变化,极大地增强了聊天机器人的会话能力。在本文中,我们对最近的文献进行了详细的调查。我们查阅了过去五年的许多与聊天机器人有关的出版物。然后,我们介绍了与我们的主题相关的不同工作,以及基于深度学习模型构建智能会话代理所需的AI概念。最后,我们提出了构建医疗辅助智能聊天机器人的功能架构。

Knowledge Management in the Expert Model of the Smart Tutoring System 智能辅导系统专家模型中的知识管理
Fatima-Zohra Hibbi, O. Abdoun, Haimoudi El Khatir
Several studies have identified the importance of knowledge domain in the intelligent tutoring system. However, this system required a knowledge processing especially in the expert model. In this paper, we report that the combination of the state of the activity (Implicit/ explicit) and the knowledge processing of: declarative, procedural and conditional knowledge is mandated to compare the learner's behavior with that of an expert in regard to assessing their knowledge. The implementation of the expert model problem will be executed using the Bayesian network. For that purpose, the integration of the Bayes Network will be: the probability of the types of Knowledge (Declarative, Procedural or Conditional) and the choice is based on two criteria; the first one is the type of assessment (Memorization, Administration, Expertise) and the status (Explicit/Implicit).
一些研究已经确定了知识领域在智能教学系统中的重要性。但是,该系统需要对专家模型进行知识处理。在本文中,我们报告了活动状态(隐式/显式)和陈述性、程序性和条件性知识的知识加工的结合,以比较学习者在评估他们的知识方面的行为与专家的行为。专家模型问题的实现将使用贝叶斯网络来执行。为此,贝叶斯网络的整合将是:知识类型(声明性、程序性或条件性)的概率,选择基于两个标准;第一个是评估的类型(记忆、管理、专业)和状态(显性/隐性)。

Performance Assessment of Open Source IDS for improving IoT Architecture Security implemented on WBANs 基于开源IDS的物联网架构安全性能评估
Mouna Boujrad, S. Lazaar, M. Hassine
The evolution of the IoT field and its strong presence in multiple domains has raised new security challenges and concerns, which explain the large number of existing studies on this phenomenon. Despite the fact that many security solutions have been applied, security threats and vulnerabilities remain present with new leaks discovery and malicious attempt to gain unauthorized access. In this research, we tackle this problem by providing a new solution of implementing open source IDS (Intrusion Detection Systems) into an IoT architecture and we perform a comprehensive study of the performance of our selected IDS regarding their detection rate and usage consumption. The proposed model is innovative since it brings a novel approach of implementing existing IDSs over the WBANs network taking into consideration all specifications and characteristics of the different layers that compose the architecture of the IoT system implemented to monitor human health.
物联网领域的发展及其在多个领域的强大存在带来了新的安全挑战和关注,这解释了对这一现象的大量现有研究。尽管已经应用了许多安全解决方案,但安全威胁和漏洞仍然存在,包括新的泄漏发现和恶意企图获得未经授权的访问。在本研究中,我们通过提供在物联网架构中实施开源IDS(入侵检测系统)的新解决方案来解决这个问题,我们对所选IDS的检测率和使用消耗进行了全面的性能研究。所提出的模型具有创新性,因为它提供了一种在wban网络上实施现有ids的新方法,同时考虑到构成用于监测人类健康的物联网系统架构的不同层的所有规范和特征。

In this research, we tackle this problem by providing a new solution of implementing open source IDS (Intrusion Detection Systems) into an IoT architecture and we perform a comprehensive study of the performance of our selected IDS regarding their detection rate and usage consumption. The proposed model is innovative since it brings a novel approach of implementing existing IDSs over the WBANs network taking into consideration all specifications and characteristics of the different layers that compose the architecture of the IoT system implemented to monitor human health.","PeriodicalId":139072,"journal":{"name":"Proceedings of the 3rd International Conference on Networking, Information Systems & Security","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115785828","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}

It happens due to lack of attractive components of online advertising content that perceived by consumer which lead to deficit amount of consumer purchasing from online advertisement. Therefore, the rise of online advertising on consumer purchasing behavior is reviewed in this study. The methods of analyzing, classifying and prioritizing of the related components are reviewed and introduced. The mediums and effective elements of online advertising content as perceived by consumer namely the consumers' attitude towards advertising as well as the factor of decision to purchase and consumer purchasing behavior are being examined. The conceptual model of online advertising elements that influence consumer behavior is portrayed and elaborated. In particular, this research uncovers effective elements and its impact toward online advertising of consumer purchasing behavior and the theoretical contributions are discussed accordingly.
随着当今科技革命时代的到来,网络广告在大多数广告渠道中得到了突出的关注。多年来,它的商业价值急剧增长。为了实现商业价值的最大化,需要考虑网络广告中可能影响消费者购买行为的有效因素。本研究的主要目的是提供影响消费者购买行为的网络广告情境的有效概念模型。数字媒体广告通知没有明显增加。这是由于网络广告内容中缺乏消费者感知到的有吸引力的成分,导致消费者从网络广告中购买的金额不足。因此,本研究回顾了网络广告的兴起对消费者购买行为的影响。对相关部件的分析、分类和排序方法进行了综述和介绍。研究消费者感知网络广告内容的媒介和有效要素,即消费者对广告的态度、购买决策因素和消费者购买行为。对影响消费者行为的网络广告要素的概念模型进行了描述和阐述。特别地,本研究揭示了网络广告对消费者购买行为的有效因素及其影响,并讨论了相应的理论贡献。
