The current effects of rapid development, high population density in large residential areas and pressures on organizations to protect the environment, create a provocative framework for waste management in modern cities. The complexity of the process of garbage collection is large, and therefore a major concern for public authorities in terms of collection, transport and further processing of solid waste. In this paper, the authors have presented a two-step solution formed from a nearest neighbor search and genetic algorithm to optimize the path of trucks with a specified capacity for garbage collection. This method firstly performs a search for the optimal solution with a nearest neighbors' algorithm (NNA) over a set of possible solutions, and then in the second step gives that solution with other random solutions to a genetic algorithm (GA) for further improvement; the goal is to extract the solution with minimal trajectory and maximum capacity utilization of trucks that are available. Testing was done on a range of problems with a certain number of trucks, with a given capacity and the number and location of sites for waste collection.
目前的快速发展、大住宅区的高人口密度以及保护环境的组织所面临的压力,为现代城市的废物管理创造了一个具有挑衅性的框架。垃圾收集过程非常复杂,因此是公共当局在收集、运输和进一步处理固体废物方面的主要关切。在本文中,作者提出了一个由最近邻搜索和遗传算法组成的两步解,以优化具有指定容量的垃圾收集卡车的路径。该方法首先使用最近邻算法(NNA)在一组可能的解上搜索最优解,然后在第二步将该解与其他随机解一起交给遗传算法(GA)进行进一步改进;目标是以最小的轨迹和最大的可用卡车容量利用率提取解决方案。在一定数量的卡车、一定的容量以及废物收集地点的数量和位置下,对一系列问题进行了测试。

Classification is one of the most popular tasks of machine learning, which has been involved in broad applications in practice, such as decision making, sentiment analysis and pattern recognition. It involves the assignment of a class/label to an instance and is based on the assumption that each instance can only belong to one class. This assumption does not hold, especially for indexing problems (when an item, such as a movie, can belong to more than one category) or for complex items that reflect more than one aspect, e.g. a product review outlining advantages and disadvantages may be at the same time positive and negative. To address this problem, multi-label classification has been increasingly used in recent years, by transforming the data to allow an instance to have more than one label; the nature of learning, however, is the same as traditional learning, i.e. learning to discriminate one class from other classes and the output of a classifier is still single (although the output may contain a set of labels). In this paper we propose a fundamentally different type of classification in which the membership of an instance to all classes(/labels) is judged by a multiple-input-multiple-output classifier through generative multi-task learning. An experimental study is conducted on five UCI data sets to show empirically that an instance can belong to more than one class, by using the theory of fuzzy logic and checking the extent to which an instance belongs to each single class, i.e. the fuzzy membership degree. The paper positions new research directions on multi-task classification in the context of both supervised learning and semi-supervised learning.
分类是机器学习中最受欢迎的任务之一,在决策制定、情感分析和模式识别等实践中有着广泛的应用。它涉及到将类/标签分配给实例,并且基于每个实例只能属于一个类的假设。这种假设并不成立,特别是对于索引问题(当一个项目,如电影,可以属于多个类别)或反映多个方面的复杂项目,例如,概述优点和缺点的产品评论可能同时是正面和负面的。为了解决这个问题,近年来越来越多地使用多标签分类,通过对数据进行转换,允许一个实例具有多个标签;然而,学习的本质与传统学习相同,即学习区分一个类与其他类,分类器的输出仍然是单一的(尽管输出可能包含一组标签)。在本文中,我们提出了一种完全不同的分类类型,其中实例与所有类(/标签)的隶属关系由多输入-多输出分类器通过生成式多任务学习来判断。通过对5个UCI数据集的实验研究,利用模糊逻辑理论,检验实例属于单个类的程度,即模糊隶属度,从经验上证明了一个实例可以属于多个类。本文提出了在监督学习和半监督学习背景下多任务分类研究的新方向。

Safety helmet wearing detection is very essential in power substation. This paper proposed a innovative and practical safety helmet wearing detection method based on image processing and machine learning. At first, the ViBe background modelling algorithm is exploited to detect motion object under a view of fix surveillant camera in power substation. After obtaining the motion region of interest, the Histogram of Oriented Gradient (HOG) feature is extracted to describe inner human. And then, based on the result of HOG feature extraction, the Support Vector Machine (SVM) is trained to classify pedestrians. Finally, the safety helmet detection will be implemented by color feature recognition. Compelling experimental results demonstrated the correctness and effectiveness of our proposed method.

Consensus in multi-agent networks with switching topology and nonlinear dynamics 具有交换拓扑和非线性动力学的多智能体网络的一致性

This paper investigates a double-integrator consensus problem for multi-agent networks (MANs) with nonlinear dynamics, where each agent is governed by both time-varying position and velocity consensus terms. The following three cases are carefully analyzed: 1) networks with fixed topology; 2) networks with controlled switching topology; and 3) networks with random switching topology. Based on previous work [11], some sententious sufficient criteria are established for reaching consensus in MANs with fixed topology. With the help of consensus results under fixed topology, some criteria are also derived to achieve consensus for MANs with switching topology by utilizing average dwell time approach and a programmable switching signal. The next moment, in view of ergodic property and stationary distribution of Markov chain, some criteria are derived to reach consensus for MANs with random switching topology. It is worth noting that the MANs considered in the above two switching cases are composed of all or partial individual switching topologies which can be reached the desired consensus.
研究了具有非线性动力学的多智能体网络的双积分器一致性问题,其中每个智能体都受时变位置和速度一致性项的约束。仔细分析以下三种情况:1)拓扑固定的网络;2)控制交换拓扑网络;3)具有随机交换拓扑的网络。在前人的工作[11]的基础上,建立了一些简洁的充分准则,用于在固定拓扑的MANs中达成共识。利用固定拓扑下的一致性结果,利用平均停留时间法和可编程开关信号,推导出具有切换拓扑的城域网一致性的准则。其次,考虑到马尔可夫链的遍历性和平稳分布,导出了具有随机切换拓扑的MANs的一致性准则。值得注意的是,在上述两种交换情况下考虑的MANs是由可以达到期望共识的全部或部分单个交换拓扑组成的。

Modern day autonomous systems are moving away form mere automation of manual tasks to true autonomy that require them to apply human-like judgment when dealing with uncertain situations in performing complex tasks. Trust in these systems is a key enabler to fully realize this dream. A lack of trust leads to inefficient use of these systems and increases the supervision workload for humans. Conversely, an over trust in these systems leads to increased risks and exposure to catastrophic events. This paper presents a high-level analytical model to study trust dynamics in supervised autonomous system environments. Trust, in this context, is defined as a function of machine competence and the level of human control required to achieve this competence. A parametric model of machine competence is presented that allows generating different machine competence behaviors based on the task difficulty, level of supervision and machine's learning ability. The notions of perceived and desired or optimal trust, computed based on perceived and observed machine competence respectively, are introduced. This allows treating trust calibration as an optimization or control problem. The presented models provide a formal framework for developing higher-fidelity simulation models to study trust dynamics in supervised autonomous systems and develop appropriate controllers for optimizing the trust between humans and machines in these systems.
现代自主系统正在从单纯的手动任务自动化转向真正的自主,这需要它们在处理复杂任务中不确定的情况时应用类似人类的判断。对这些系统的信任是完全实现这一梦想的关键因素。缺乏信任导致这些系统的使用效率低下,并增加了人类的监督工作量。相反,对这些系统的过度信任会导致风险增加,并暴露于灾难性事件。本文提出了一个研究监督自治系统环境下信任动态的高级分析模型。在这种情况下,信任被定义为机器能力和实现这种能力所需的人类控制水平的函数。提出了一种基于任务难度、监督水平和机器学习能力的机器能力参数化模型,该模型可以生成不同的机器能力行为。引入了感知信任和期望信任或最优信任的概念,分别基于感知和观察机器能力进行计算。这允许将信任校准视为优化或控制问题。所提出的模型为开发高保真仿真模型提供了形式化框架,用于研究监督自治系统中的信任动态,并开发适当的控制器来优化这些系统中人与机器之间的信任。

As it is known, computer users who notice the existence of electronic viruses will take active measures to defend against the viruses before they prevail on networks. However, the most of former computer virus epidemic models ignore the human vigilance completely. This paper aims to understand how the human awareness prohibits virus spreading. So a new computer virus propagation model where the viral prevalence is not quite high is developed. Under moderate assumptions, this model admits one equilibrium which is virus-free. And it is shown to be globally asymptotically stable. Some numerical examples are also given. The obtained result clearly exhibits that enough vigilance greatly benefits the containment of computer viruses.
众所周知,注意到电子病毒存在的计算机用户会在病毒在网络上流行之前采取积极措施进行防御。然而,以往的计算机病毒流行模型大多完全忽略了人类的警惕性。本文旨在了解人类的意识是如何阻止病毒传播的。因此,本文提出了一种新的计算机病毒传播模型。在适度的假设下,该模型允许一种无病毒的平衡。并且证明了它是全局渐近稳定的。并给出了一些数值算例。所得结果清楚地表明,足够的警惕性对遏制计算机病毒大有好处。

In this paper, we explore some aspect of the asymptotic stability of stochastic impulsive systems with variable-time impulses. At the beginning we consider the case that the trajectory of the stochastic system intersects each surface exactly once. Then we shall show that under the well-selected conditions the systems with variable-time impulsive can be changed to the systems with the fixed-time impulsive. Some criteria ensuring the stability in the p-th moment are obtained by using stochastic analysis theory. An illustrative example and simulations are given to show the effectiveness of our results.

An illustrative example and simulations are given to show the effectiveness of our results.","PeriodicalId":260701,"journal":{"name":"2017 Ninth International Conference on Advanced Computational Intelligence (ICACI)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131329017","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}

The simulation of a navigation heterogeneous group of robots; unmanned ground vehicle (UGV), unmanned aerial vehicle (UAV) through GPS, digital map and image processing using probabilistic roadmap method (PRM) are addressed throughout this paper. Having the capacitato navigate accurately is one of the major abilities of a mobile robot to effectively execute a variety of jobs including manipulation, docking, and transportation. To achieve the desired navigation accuracy, mobile robots are typically equipped with on-board sensors to observe persistent features in the environment, to estimate their pose from these observations, and to adjust tneir motion accordingly [1]. According to the scenario of the mission, UAV takes off from UGV, surveys the terrain and transmits Image terrestrial robot. UGV processes images, calculating the optimum trajectory method Probabilistic Roadmap with the help of GPS, and provide standalone navigate through the outdoor based on the calculated route. The group of robots is: UGV Belarus-132N and UAV Phantom-2 Vision quadcopter.
机器人导航异构群的仿真研究本文讨论了无人驾驶地面车辆(UGV)、无人驾驶飞行器(UAV)、数字地图和使用概率路线图方法(PRM)的图像处理。具有精确导航能力是移动机器人有效执行各种工作(包括操作、对接和运输)的主要能力之一。为了达到理想的导航精度,移动机器人通常配备机载传感器来观察环境中的持续特征,并根据这些观察结果估计其姿态,并相应地调整其运动[1]。根据任务场景,UAV从UGV上起飞,对地形进行测量并传送图像给地面机器人。UGV对图像进行处理,在GPS的帮助下计算最优轨迹方法Probabilistic Roadmap,并根据计算出的路线在室外提供独立导航。这组机器人是:UGV白俄罗斯- 132n和无人机幻影-2视觉四轴飞行器。
