Solving Multiconstrained Quality of service Multicast Routing Problem using Simulated Annealing Algorithm 用模拟退火算法求解多约束服务质量组播路由问题
Sabrina Tadjine, Ali Lemouari, M. Kara
Multicast routing is a telecommunication technique that simultaneously sending data from one, or more source to several destination. Multimedia applications are widely used. These applications require several QoS constraints. This paper proposes a multi-constrained QoS multicast routing method using simulated annealing metaheuristic. The proposed algorithm minimizes the cost of multicast tree while satisfying bandwidth, delay, delay jitter, and packet loss constraints. In the proposed approach we use R-Path move method to construct neighbors. The simulation results demonstrate that our algorithm is better for cost performance, best multicast tree obtained, compared to others algorithms.
多播路由是一种同时从一个或多个源向多个目的地发送数据的电信技术。多媒体应用被广泛使用。这些应用程序需要几个QoS约束。提出了一种基于模拟退火元启发式的多约束QoS组播路由方法。该算法在满足带宽、延迟、延迟抖动和丢包约束的同时,使组播树的开销最小化。在该方法中,我们使用R-Path移动方法来构造邻居。仿真结果表明,与其他算法相比,该算法具有更好的性价比,得到了最好的组播树。

Evaluation of Local Binary Pattern for Osteoporosis Classification 局部二元模式对骨质疏松症分类的评价
Mebarkia Meriem, Meraoumia Abdallah, Houam Lotfi, Khemaissia Seddik
Deterioration of the bone’s microarchitecture and low bone mineral density, which results in increased fragility of bone, are symptoms of the disease osteoporosis, which decreases bone mass. Early osteoporosis identification can prevent the disease and predict fracture risk. Usually, the diagnosis is based on the analysis of X-ray images. However, the healthy and osteoporotic subject radiography shows a great resemblance. This study aims to develop an evaluation of an automatic osteoporosis identification system based on texture analysis. This paper proposes a Local Optimal Oriented Pattern (LOOP) to address some of the shortcomings of existing feature descriptors such as Local Binary Pattern (LBP) and Local Directional Pattern (LDP). Ensemble and SVM learning algorithms were used for the classification task. The obtained results were compared with some state-of-art methods used in the literature. Experimental results show that the proposed approach outperforms the previous binary descriptor in terms of recognition accuracy proving that the proposed approach is efficient for real clinical applications.
骨质疏松症的症状是骨骼微结构恶化和骨密度低,导致骨骼更加脆弱。骨质疏松症会导致骨量减少。早期发现骨质疏松症可以预防疾病和预测骨折风险。通常,诊断是基于对x射线图像的分析。然而,健康者与骨质疏松者的x线片表现出很大的相似性。本研究旨在开发一种基于纹理分析的骨质疏松症自动识别系统。针对现有特征描述符如局部二值模式(LBP)和局部定向模式(LDP)的不足,提出了一种局部最优定向模式(LOOP)。集成和支持向量机学习算法用于分类任务。所得结果与文献中使用的一些最先进的方法进行了比较。实验结果表明,该方法在识别精度上优于先前的二元描述符,证明了该方法在实际临床应用中的有效性。

Prosodic Modelling based Speaker Identification 基于韵律模型的说话人识别
Khadidja Nesrine Boubakeur, M. Debyeche, A. Amrouche, Youssouf Bentrcia
The use of prosodic characteristics, mainly pitch and intensity, for speaker identification in noisy environments is examined in this work. To make the acoustic models more resistant to the variability in the speech signal in noisy situations, these features are supplemented with cepstral parameters. As a consequence, two systems for Automatic Speaker Identification (ASI) in the independent mode of text are implemented. The first based on Hidden Markov Models (HMM), whereas Support Vector Machines (SVM) are employed in the second. The addition of prosodic features improves recognition, especially in high-noise environments. The performance of SVM-based systems is better than HMM-based systems

Active Contour Based Segmentation and CNN for Palmprint Recognition 基于主动轮廓分割和CNN的掌纹识别
Wafaa Mohammed Cherif, T. B. Stambouli
Biometric authentication has proven to be a successful strategy for correctly recognizing a person’s identification. in particular, palmprint-based biometric systems have received increased attention in recent years, due to its high identification accuracy, utility and acceptance. The traditional method of palmprint recognition requires the extraction of palmprint characteristics before the classification, which has an impact on the recognition rate. To address this problem, the CNN Model LeNet-5 is used to propose a method for extracting discriminative features using Convolution Neural Networks. First, Segmentation based on Active Contours is used for ROI palmprint Extraction. Then the convolutional neural network is trained based on the extracted ROI region by selecting the optimal learning rate and hyperparameters. Finally, the palmprint was identified. The experiments demonstrated that The ROI extraction system could accurately find the most suitable Regions Of Interest, compared with existing main ROI extraction methods, our model proved competitive with the state-of-the-art. We achieved an overall accuracy of 97% using two hand databases : IITD hand database, and Tongji Contactless Palmprint Dataset.
生物特征认证已被证明是正确识别个人身份的一种成功策略。近年来,基于掌纹的生物识别系统因其较高的识别精度、实用性和可接受性而受到越来越多的关注。传统的掌纹识别方法需要在分类前提取掌纹特征,这对识别率有一定的影响。为了解决这一问题,本文利用CNN模型LeNet-5提出了一种利用卷积神经网络提取判别特征的方法。首先,将基于活动轮廓的分割用于ROI掌纹提取。然后根据提取的ROI区域选取最优学习率和超参数对卷积神经网络进行训练。最后对掌纹进行了识别。实验表明,该ROI提取系统能够准确地找到最合适的感兴趣区域,与现有的主要ROI提取方法相比,该模型具有较强的竞争力。我们使用两个手部数据库:IITD手部数据库和同济非接触式掌纹数据集,达到了97%的总体准确率。

Image Retrieval Based on Dynamic Weighted Patterns 基于动态加权模式的图像检索
Rahima Boukerma, Bachir Boucheham, Salah Bougueroua
In this paper we present Dynamic Pattern Weighting (DPW), a novel method for Content-Based Image Retrieval (CBIR). This method has the capability to reduce the semantic gap by giving dynamically an appropriate weight to each pattern of the image according to the image class and the importance of the pattern in the image. After an offline optimization phase using a metaheuristic algorithm, a weight vector is obtained for each class of the image database. Thereafter, to choose the proper weight vector for the query image, an assumed class is determined by applying K-nearest neighbors algorithm. Furthermore, for each individual pattern a different importance is determined adaptively, depending on the occurrences number of the pattern in the image. The proposed method has been evaluated using four local pattern methods to extract image texture features. Experiments on Corel-1K database reveals that the performance of the dynamic weighted methods outperforms the other methods.
本文提出了一种基于内容的图像检索(CBIR)的新方法——动态模式加权(DPW)。该方法根据图像的类别和模式在图像中的重要程度,动态地赋予图像中每个模式适当的权重,从而减小了语义差距。采用元启发式算法进行离线优化后,得到图像数据库中每一类图像的权重向量。然后,应用k近邻算法确定假设类,为查询图像选择合适的权重向量。此外,对于每个单独的图案,根据图案在图像中的出现次数,自适应地确定不同的重要性。用四种局部模式方法对该方法进行了评价,以提取图像纹理特征。在Corel-1K数据库上的实验表明,动态加权方法的性能优于其他方法。

New hybrid Particle Swarm and Dragonfly Algorithm for features selection 基于混合粒子群和蜻蜓算法的特征选择
Bilal Benmessahel
We are nowadays obligated to deal with rich datasets with exceptionally high dimensions due to big data and IoT. Therefore, a technique known as feature selection (FS) is employed to carry out any machine learning activity or get insights from such dimensions data. One of the most fundamental issues in the analysis of high-dimensional data is feature selection. In this work, we suggest a new approach to the problem of feature selection, which involves selecting a subset of pertinent features for the research topic from a wide number of attributes. To tackle the FS problem, a new bio-inspired algorithm called PSODA is developed in this study, and a novel approach is suggested to maintain a balance between the capacities for exploration and exploitation. The Dragonfly Technique (DA) and the particle swarm optimization (PSO) approach were combined to create the suggested algorithm. Over the most popular datasets in literature, the proposed approach was adequately compared to other algorithms. The outcomes show how PSODA outperforms all other algorithms.
如今,由于大数据和物联网的出现,我们不得不处理具有极高维度的丰富数据集。因此,一种被称为特征选择(FS)的技术被用于执行任何机器学习活动或从这些维度数据中获得见解。特征选择是高维数据分析中最基本的问题之一。在这项工作中,我们提出了一种解决特征选择问题的新方法,该方法涉及从大量属性中选择与研究主题相关的特征子集。为了解决FS问题,本研究提出了一种新的基于生物的PSODA算法,并提出了一种保持探索和开发能力平衡的新方法。将蜻蜓技术(Dragonfly Technique, DA)和粒子群算法(particle swarm optimization, PSO)相结合,建立了该算法。在文献中最流行的数据集上,所提出的方法与其他算法进行了充分的比较。结果显示PSODA如何优于所有其他算法。

DZRobot4Kids: a mobile robot application for educational games DZRobot4Kids:用于教育游戏的移动机器人应用程序
Meriem Belguidoum, Ammar Hamlaoui, Houssem Eddine Bendaas
Learning through games is a pedagogical approach that promotes the use of playful activities to stimulate many aspects of children’s development and learning. We know that children spend a long duration on social media and intensive games that have a negative impact on their development and behavior. Therefore, it is important to teach them how to use their smartphones using fun and creative robot educational games that help in developing their social, emotional, and soft skills.Existing educational robot games are too expensive for Algerian parents and the government, that why Algerian children could not access and use them even in school or at home. For that reason, This project aims to develop an educational robot game accessible to everyone, based on a robot that moves on a map using a mobile application that controls the movement of this robot in real-time, according to the children’s answers.We have adopted the Scrum agile methodology for the development of this project for more flexibility, adaptability, and quality, and in the requirement analysis and design phases, we used SysML language which is suitable for modeling IoT-based applications.We have offered a scalable mobile application adaptable to the child’s age and learning level. Many educational games are offered: mental calculations, learning letters, numbers, objects, and languages through word games, and recognition of hidden objects; all are available in three languages, Arabic, French, and English.
通过游戏学习是一种教学方法,它促进使用有趣的活动来刺激儿童发展和学习的许多方面。我们知道,孩子们花在社交媒体和密集游戏上的时间很长,这对他们的发展和行为产生了负面影响。因此,重要的是教他们如何使用他们的智能手机,使用有趣和创造性的机器人教育游戏,帮助发展他们的社交,情感和软技能。对于阿尔及利亚的父母和政府来说,现有的教育机器人游戏过于昂贵,这就是为什么阿尔及利亚的孩子们即使在学校或家里也无法接触和使用它们。基于这个原因,这个项目旨在开发一个教育机器人游戏,每个人都可以访问,基于一个机器人在地图上移动,根据孩子们的答案,使用一个移动应用程序实时控制这个机器人的运动。为了提高项目的灵活性、适应性和质量,我们采用了Scrum敏捷开发方法,在需求分析和设计阶段,我们使用了SysML语言,该语言适用于基于物联网的应用程序建模。我们提供了一个可扩展的移动应用程序,适用于孩子的年龄和学习水平。提供了许多教育类游戏:心算,通过文字游戏学习字母、数字、物体和语言,以及识别隐藏物体;所有网站都有阿拉伯语、法语和英语三种语言版本。

A Multi-Threshold Energy approach for Energy Harvesting WSN 能量采集WSN的多阈值能量方法
Abdelmalek Bengheni
This article offers a Multi-threshold Energy approach for Energy-Harvesting Wireless Sensor Network (MTE-EHWSN) to enhance the lifetime and Wireless Sensor Network (WSN) performance by minimizing the duty-cycle more radically and profoundly of each sensor node. The use of MTE-EHWSN by any sensor node in the WSN allows for energy harvesting management and energy consumption, helping it to ensure its balance and to dynamically regulate its duty-cycle through calculating its sleep interval more radically and profoundly according on the amount of current remaining energy. In addition, our proposed approach allows WSN to function well in the case of low energy harvesting. Through OMNeT++/MiXiM simulations, we demonstrated that MTE-EHWSN approach enhances the WSN performance compared to other current energy harvesting administration approach such as EH2M by incorporating these two approaches into the sender-initiated MAC mode of communication.
本文提出了一种用于能量收集无线传感器网络(MTE-EHWSN)的多阈值能量方法,通过更彻底、更深入地最小化每个传感器节点的占空比来提高无线传感器网络(WSN)的寿命和性能。在WSN中,任何传感器节点都可以使用MTE-EHWSN进行能量收集管理和能量消耗,帮助其确保平衡,并根据当前剩余能量更彻底、更深入地计算其睡眠间隔来动态调节其占空比。此外,我们提出的方法允许WSN在低能量收集的情况下良好地工作。通过omnet++ /MiXiM仿真,我们证明了MTE-EHWSN方法通过将这两种方法结合到发送方发起的MAC通信模式中,与其他当前的能量收集管理方法(如EH2M)相比,可以提高WSN的性能。

The Effect of Regularization on the MAP-OSEM Algorithm for PET Reconstruction 正则化对PET重构MAP-OSEM算法的影响
Abdelwahhab Boudjelal, Bilal Attallah, A. Elmoataz, Y. Chahir, Abdelhak Goudjil
In this paper, we study the algorithm of MAP-OSEM for PET reconstruction which is a well known iterative algorithm. It is desired to use a spatial regularization technique can improve the quality of reconstructed images and help to provide accurate diagnosis. The MAP-OSEM algorithm is a powerful image reconstruction algorithm that has been used in a variety of medical imaging applications, including PET reconstruction. In this work, we use the regularized MAP-OSEM algorithm that incorporates a regularization term into the objective function. The regularization term is used to promote smoothness in the reconstructed image, and it is typically chosen based on prior knowledge about the image. The MAP-OSEM algorithm is a gradient ascent optimization method which seeks to maximize the posterior distribution of an image by taking into account a Poisson-Gaussian noise model for the likelihood and a uniform prior to reduce bias. The objective function is maximized by the gradient ascent optimization method.

The MAP-OSEM algorithm is a gradient ascent optimization method which seeks to maximize the posterior distribution of an image by taking into account a Poisson-Gaussian noise model for the likelihood and a uniform prior to reduce bias. The objective function is maximized by the gradient ascent optimization method.","PeriodicalId":403927,"journal":{"name":"2022 2nd International Conference on New Technologies of Information and Communication (NTIC)","volume":"100 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128876472","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}

Evolution of passive user interests by analyzing Social Network activities 通过分析社交网络活动分析被动用户兴趣的演变
Nour El Houda Boulkrinat, N. Benblidia, A. Meziane
This paper addresses the issue of interest evolution based on social activities. The evolution of social interests emphasizes the use of various types of information and relationships between users. It’s based on social interactions (share, comment, like, etc.) and on resources (text, images, videos, etc.). Although evolution techniques have undergone distinct developments in recent years, they still have limitations, particularly when the user is inactive and the data is sparse. The evolution and detection of the passive user interests are challenging because this kind of user does not or rarely interacts in social networks and has few or no friends. In this paper, we present a novel evolutionary approach to detect the passive user interests based on the research history and resources clicked, taking into account the temporal factors of the information. We applied resource indexing, we elicited the top interests by calculating the weight of each term in queries, and we used a similarity function to further enrich the interests of passive users. An evolution system based on this approach has been developed, and experiments have been conducted using the Facebook social network. The evaluation results demonstrated that the proposed approach returns positive results and solves the cold start problem.
本文探讨了基于社会活动的兴趣演化问题。社会利益的演变强调了各种类型信息的使用和用户之间的关系。它基于社交互动(分享、评论、喜欢等)和资源(文本、图像、视频等)。尽管进化技术近年来有了明显的发展,但它们仍然有局限性,特别是在用户不活跃和数据稀疏的情况下。被动用户兴趣的演变和检测具有挑战性,因为这类用户很少或很少与社交网络互动,并且很少或根本没有朋友。在本文中,我们提出了一种新的基于研究历史和点击资源的进化方法来检测被动用户兴趣,并考虑了信息的时间因素。我们应用资源索引,通过计算查询中每个词的权重来获得最热门的兴趣,并使用相似度函数来进一步丰富被动用户的兴趣。基于这种方法的进化系统已经被开发出来,并在Facebook社交网络上进行了实验。评价结果表明,该方法具有良好的效果,解决了冷启动问题。
