A FIPA-ACL based communication utility for Unity 一个基于FIPA-ACL的Unity通信工具
Alejandro Rodríguez-Arias, B. Guijarro-Berdiñas, N. Sánchez-Maroño
Multi-agent systems (MAS) allow facing complex, heterogeneous, distributed problems difficult to solve by only one software agent. Games often provide very adequate problems for the use of MAS. In the field of Games, Unity is one of the most used video game engines and allows the development of intelligent agents in 2D/3D virtual environments. However, although Unity allows working in multi-agent environments it does not provide functionalities to facilitate the development of genuine MAS. One crucial functionality is to allow agents to communicate and understand each other through an agent communication language (ACL). The objective of this work is to supply Unity with this capacity, adding support for the creation, sending and reception of messages. As a result, a communication system and an ACL are provided that facilitate the development of MAS in Unity, allowing to solve problems that require collaborative solutions among agents.
多智能体系统(MAS)允许面对复杂的、异构的、分布式的问题,而这些问题很难只用一个软件代理来解决。游戏经常为MAS的使用提供非常充分的问题。在游戏领域,Unity是最常用的视频游戏引擎之一,它允许在2D/3D虚拟环境中开发智能代理。然而,尽管Unity允许在多代理环境中工作,但它并没有提供促进真正MAS开发的功能。一个关键的功能是允许代理通过代理通信语言(ACL)进行通信并相互理解。这项工作的目标是为Unity提供这种能力,增加对创建、发送和接收消息的支持。因此,提供了一个通信系统和ACL,促进了MAS在Unity中的开发,允许解决需要在代理之间协作解决的问题。

Resolving Multi-user Conflicts in a Smart Building using RBAC 利用RBAC解决智能建筑中的多用户冲突
Hamida Belkhiria, Fairouz Fakhfakh, I. Rodriguez
In the world of cyber-physical systems, the emergence of Smart Living Spaces (SLS) trend gives people the opportunity to benefit from new ways of living. Such technological trend that involves several aspects of daily life, allows the residents of the space to better customize and control their environment. SLS emphasizes, mainly, energy conservation, convenience and comfort as well as health care concerns. They are gradually realized in practical applications e.g. household appliances and medical and care systems. The SLS related applications are intended to improve the quality of life for users by ensuring that their needs are met, thereby producing more sustainable use of energy in a given living space. Moreover, the development of SLS technology makes the devices around us “smart”. This has brought lot of challenges, one of which is the access control management. In a SLS, there has to be a robust access control mechanism in place in order to ensure an authorized access to devices. This paper focuses on the use of Role Based Access Control (RBAC) model as an efficient means to prevent unauthorized users from gaining access to devices in a Smart Building. Then, to guarantee that only the approved users can access the devices, a Smart Building Manager (SBM) is required to ask an evaluation engine to evaluate requests. We separate the evaluation as a third party in the smart building in which we propose RBAC with domains that stands our policy model. We implement the policy model for the aim to ensure a fine grained access control to a smart building application while evolving from a mono-user to a multi-user.
在网络物理系统的世界中,智能生活空间(SLS)趋势的出现使人们有机会从新的生活方式中受益。这种技术趋势涉及到日常生活的几个方面,让空间的居民更好地定制和控制他们的环境。SLS主要强调节能、方便、舒适以及健康。它们逐渐在实际应用中实现,例如家用电器和医疗保健系统。SLS相关的应用旨在通过确保满足用户的需求来提高他们的生活质量,从而在给定的生活空间中产生更可持续的能源利用。此外,SLS技术的发展使我们周围的设备变得“智能”。这带来了许多挑战,其中之一就是访问控制管理。在SLS中,必须有一个健壮的访问控制机制,以确保对设备的授权访问。本文重点研究了基于角色的访问控制(RBAC)模型作为一种有效的手段来防止未经授权的用户访问智能楼宇中的设备。然后,为了保证只有通过审批的用户才能访问设备,需要SBM (Smart Building Manager)请求评估引擎对请求进行评估。我们将评估作为智能建筑中的第三方进行分离,在智能建筑中,我们提出RBAC与符合我们策略模型的域。我们实现策略模型的目的是确保对智能建筑应用程序进行细粒度的访问控制,同时从单用户发展到多用户。

Agent-mediated application emergence through reinforcement learning from user feedback 通过强化学习从用户反馈agent介导的应用涌现
Walid Younes, F. Adreit, Sylvie Trouilhet, J. Arcangeli
Cyber-physical and ambient systems surround the human user with applications that should be tailored as possible to her/his preferences and the current situation. We propose to build them automatically and on the fly by composition of software components present at the time in the environment, but without prior expression of the user’s needs or process specification or composition model. In order to produce knowledge useful for automatic composition in the absence of an initial guideline, we have developed a generic solution based on lifelong online reinforcement learning. It is decentralized within a multi-agent system where agents learn incrementally from user feedback to satisfy her/him. Different use cases have been experimented in which applications, adapted to the user and the situation, are composed and emerge automatically and continuously.
网络物理和环境系统围绕着人类用户,应用程序应该尽可能地根据他/她的偏好和当前情况进行定制。我们建议通过组合环境中当时存在的软件组件来自动地、动态地构建它们,但不需要事先表达用户需求、过程规范或组合模型。为了在没有初始指导的情况下产生对自动作文有用的知识,我们开发了一个基于终身在线强化学习的通用解决方案。它在多代理系统中是分散的,代理从用户反馈中逐渐学习以满足她/他。已经试验了不同的用例,在这些用例中,适应用户和情况的应用程序是自动和连续地组成和出现的。

QoE Influence Factors (IFs) classification Survey focusing on User Behavior/Engagement metrics QoE影响因素(IFs)分类调查侧重于用户行为/粘性指标
Fatima Laiche, Asma BEN LETAIFA, T. Aguili
Over the last few years, the evolution of multimedia streaming services has resulted in growth and significant explorations of Quality of Experience (QoE) since the concept of QoE is gaining an enormous research effort, but it is still complex to estimate. This estimation can be influenced by a wide range of quality affecting factors. In this work, we provide standard definitions, we review and survey existing models to classify QoE Influence Factors (IFs). Moreover, we present a classification of the QoE IFs into four groups: system factors, context factors, human factors, and social-behavioral factors. Finally, regarding the QoE IFs, we highlight some relevant studies. We believe that our overview and findings can provide an understanding of the related quality affecting factors and QoE assessment approaches over video communications.
在过去的几年中,多媒体流媒体服务的发展导致了体验质量(QoE)的增长和重大探索,因为QoE的概念正在获得大量的研究工作,但它仍然很复杂。这种估计可能受到各种质量影响因素的影响。在这项工作中,我们提供了标准的定义,我们回顾和调查了现有的模型来分类QoE影响因素(IFs)。此外,我们将质量质量评价因子分为四类:系统因素、环境因素、人为因素和社会行为因素。最后,针对质量质量指标,我们重点介绍了一些相关研究。我们相信我们的综述和研究结果可以为理解视频通信的相关质量影响因素和质量质量评估方法提供帮助。

Autonomic Coordination of IoT Device Management Platforms 物联网设备管理平台的自主协调
Emna Mezghani, Samuel Berlemont, Marc Douet
With the adoption of the Internet of Things (IoT), devices become integrated in our daily lives. These devices are more and more interdependent, either by guaranteeing connectivity, or by providing data for complex services. In an ever-evolving IoT context, continuously managing these connected objects is crucial, to handle vulnerabilities, ensure their well-functioning, and add new services. These features fall under the scope of Device Management (DM). The distribution and scalability of DM platforms become all the more exacerbated as device profiles and deployment use cases get more heterogeneous. Thus, multiple actors are involved in IoT services, with their respective, isolated, DM platforms. However, DM operations, such as reboots and firmware updates, have a direct impact on the state of devices, which requires awareness across DM platforms. In this paper, we address conflicts linked to connectivity dependencies, which may arise during the simultaneous execution of DM operations on interdependent devices. Hence, we propose a coordinator that collects DM operation intentions from isolated DM platforms and detects the relevant dependencies, so as to plan and orchestrate the execution of these operations. An evaluation of this middleware is presented, with perspectives for industrial applications.
随着物联网(IoT)的采用,设备融入了我们的日常生活。这些设备越来越相互依赖,要么通过保证连接,要么通过为复杂的服务提供数据。在不断发展的物联网环境中,持续管理这些连接的对象对于处理漏洞,确保其正常运行并添加新服务至关重要。这些特性属于设备管理(DM)的范围。随着设备配置文件和部署用例变得更加异构,DM平台的分布和可扩展性变得更加严重。因此,物联网服务涉及多个参与者,他们各自独立的DM平台。但是,DM操作(如重启和固件更新)会直接影响设备的状态,这需要跨DM平台的感知。在本文中,我们解决了与连接依赖相关的冲突,这些冲突可能在相互依赖的设备上同时执行DM操作期间出现。因此,我们提出了一个协调器,它从隔离的DM平台收集DM操作意图,并检测相关的依赖关系,从而计划和编排这些操作的执行。对该中间件进行了评估,并从工业应用的角度进行了分析。

STCMS: A Smart Thermal Comfort Monitor For Senior People STCMS:老年人智能热舒适监测仪
K. Katsarou, Chahinez Ounoughi, Amira Mouakher, C. Nicolle
Undoubtedly, the steady increase in the number of elderly people is not to be underestimated. These demographic changes call attention to new challenges regarding adequate aging-in-place strategies. Since the majority of the senior population spend up to 90% of their time indoors, appropriate and comfortable housing represents an important foundation for such strategies. In this respect, different types of data gathered from sensors, connected devices, and Internet of Things (IoT) technologies come to play an important role to support services for the elderly population in indoor environments. One of the aspects of concern is thermal comfort. In this paper, we introduce a new deep learning-based model framework named STCMS, that uses both Long-Short Term Memory (LSTM) and Deep Neural Networks (DNN) architectures, dedicated to predicting thermal comfort for elderly people. Experiments based on the publicly available dataset, show that our proposed models outperform the pioneering approaches of the literature on the agreed assessment metrics, particularly with an accuracy that varies between 80.29% to 88.16% using only internal and external temperatures data. The proposed approach can be used as a smart thermostat solution integrated into smart home ecosystems dedicated to elderly people. Thus, it would contribute simultaneously to improve their well-being and to reduce energy consumption and health costs.
毫无疑问,老年人数量的稳步增长是不可低估的。这些人口变化要求人们注意适当的就地老龄化战略方面的新挑战。由于大多数老年人90%的时间都在室内度过,因此适当舒适的住房是此类策略的重要基础。在这方面,从传感器、连接设备和物联网(IoT)技术收集的不同类型的数据将在室内环境中为老年人提供服务方面发挥重要作用。人们关心的一个方面是热舒适。在本文中,我们介绍了一种新的基于深度学习的模型框架,称为STCMS,它使用长短期记忆(LSTM)和深度神经网络(DNN)架构,致力于预测老年人的热舒适。基于公开数据集的实验表明,我们提出的模型在商定的评估指标上优于文献中的开创性方法,特别是在仅使用内部和外部温度数据时,准确率在80.29%至88.16%之间。该方法可以作为智能恒温器解决方案集成到专门针对老年人的智能家居生态系统中。因此,它将同时有助于改善他们的福祉,并减少能源消耗和保健费用。

Privacy Preserving Statistical Detection of Adversarial Instances 对抗实例的隐私保护统计检测
M. Alishahi, Nicola Zannone
Adversarial instances are malicious input designed by attackers to cause a classification model to make a false prediction, e.g. in Spam detection. Effective solutions have been proposed to detect and block adversarial instances in real time. Still, the proposed approaches fail to detect adversarial instances over private input (required by many on-line platforms analyzing sensitive personal data).In this work, we propose a novel framework that applies a statistical test to detect adversarial instances when data under analysis are in private format. The practical feasibility of our approach in terms of computation cost is shown through an experimental evaluation.
对抗性实例是攻击者设计的恶意输入,以导致分类模型做出错误的预测,例如在垃圾邮件检测中。已经提出了实时检测和阻止对抗实例的有效解决方案。尽管如此,所提出的方法未能检测到私人输入(许多在线平台分析敏感个人数据所需要的)的对抗性实例。在这项工作中,我们提出了一个新的框架,当被分析的数据是私有格式时,该框架应用统计检验来检测对抗实例。通过实验验证了该方法在计算成本方面的实际可行性。

The practical feasibility of our approach in terms of computation cost is shown through an experimental evaluation.","PeriodicalId":114214,"journal":{"name":"2020 IEEE 29th International Conference on Enabling Technologies: Infrastructure for Collaborative Enterprises (WETICE)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115864975","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}
