Dual Denoising Autoencoder Feature Learning for Cancer Diagnosis 双去噪自编码器特征学习用于癌症诊断
Yuqing Gao, Wing W. Y. Ng, Ting Wang, S. Kwong
Microarray data analysis has emerged as a strong tool for cancer diagnosis. Nevertheless, researches on it are significantly challenging as the microarray datasets are imbalanced and high-dimensional with relatively small sample size. In this paper, we utilized Dual Denoising Autoencoder Features (DDAF), which integrates two Denoising Auto-Encoders (DAE) with different activation function to map the features for both minority and majority classes into a better classification representation. The experimental results on four typical microarray datasets show that the DDAF outperforms the Dual Autoencoder Features (DAF) and the Cost-sensitive Oversampling Stacked Denoising Auto-Encoder (CO-SDAE), rendering the robust ability for dimensionality reduction and imbalanced classification.
微阵列数据分析已成为癌症诊断的有力工具。然而,由于微阵列数据集不平衡、高维且样本量相对较小,因此对其研究具有很大的挑战性。在本文中,我们利用双去噪自编码器特征(Dual Denoising Autoencoder Features, DDAF),它集成了两个具有不同激活函数的去噪自编码器(Denoising auto - encoder, DAE),将少数类和多数类的特征映射为更好的分类表示。在4个典型微阵列数据集上的实验结果表明,DDAF算法优于双自编码器特征(Dual Autoencoder feature, DAF)和代价敏感过采样堆叠去噪自编码器(CO-SDAE)算法,具有较强的降维和不平衡分类能力。

Intrusion Detection System Using Convolutional Neuronal Networks: A Cognitive Computing Approach for Anomaly Detection based on Deep Learning 基于卷积神经网络的入侵检测系统:基于深度学习的异常检测认知计算方法
Lalin Heng, T. Weise
Network security is becoming more and more vital in our world as the internet permeates both the industry and our private life. Today, the means of production are networked and controlled by intelligent manufacturing process and the majority of the people are constantly connected to information systems by using mobile phones. Intrusion detection systems (IDS) are software components which detect attacks and malicious attempts to gain access to networks. How to design such systems efficiently is a question of both practical and research interest. We propose and approach based on cognitive computing using deep learning for this purpose. Our method has two main advantages: It is highly efficient and accurate, yet it is simple, builds on existing standard software, and can easily be implemented and enriched with domain knowledge by an expert from computer security with little background in machine learning. Furthermore, with the parallelism and big data support of the platform, our method will also scale well with the size of the dataset available for training. In deep learning, Convolutional neural network (CNNs) have successfully been applied to a variety of classification tasks in various fields. They are also available in easily accessible and scalable standard frameworks such as TensorFlow. In this paper, we present an approach to constructing an IDS based on CNN. Network traffic is presented based on features of TCP/IP connections and the approach is trained based on known attack signatures. We evaluate this approach using the widely available NSLKDD dataset. We are able to achieve the accuracy, precision, recall and $F_{1}$-score of 98.92%, 99.82%, 92.34%, and 96.34%, respectively. Based on its simplicity and these surprisingly good performance results, we can conclude that our approach is highly suitable for constructing IDS.
随着互联网渗透到工业和我们的私人生活中,网络安全在我们的世界中变得越来越重要。今天,生产资料网络化,由智能制造过程控制,大多数人通过手机不断地连接到信息系统。入侵检测系统(IDS)是检测攻击和恶意访问网络企图的软件组件。如何有效地设计这样的系统是一个既有现实意义又有研究意义的问题。为此,我们提出并采用基于认知计算的深度学习方法。我们的方法有两个主要优点:它是高效和准确的,但它是简单的,建立在现有的标准软件上,可以很容易地实现和丰富领域知识的计算机安全专家在机器学习背景很少。此外,由于平台的并行性和大数据支持,我们的方法也可以很好地扩展用于训练的数据集的大小。在深度学习中,卷积神经网络(cnn)已经成功地应用于各个领域的各种分类任务。它们也可以在易于访问和可扩展的标准框架(如TensorFlow)中使用。本文提出了一种基于CNN的IDS构造方法。基于TCP/IP连接的特征来描述网络流量,并基于已知的攻击特征对该方法进行训练。我们使用广泛可用的NSLKDD数据集来评估这种方法。我们能够实现准确率98.92%,精密度99.82%,召回率92.34%,$F_{1}$-score 96.34%。基于它的简单性和这些令人惊讶的良好性能结果,我们可以得出结论,我们的方法非常适合构造IDS。

A Risk Assessment Model of Stampede Accidents in Primary and Secondary School Teaching Buildings Based on Bayesian Network 基于贝叶斯网络的中小学教学楼踩踏事故风险评估模型
R. Zou, Yu Zou, Bihai Zou, Xin Liu
Primary and secondary schools is a centralized area of population, and the teaching buildings are the main places where the campus stampede accidents occurred. In order to reduce the occurrence of stampede accidents in primary and secondary school teaching buildings and improve the pertinence of risk prevention and control, a risk assessment and analysis model based on Bayesian network (BN) was worked out. Firstly, the risk factors of the stampede accidents in teaching buildings were summarized, and the causal relationship of each factor was analyzed, thus the BN structure was built. Then, the network parameters are determined by the data collected in the reference and the expert assignment. Finally, diagnostic reasoning was used to test and debug the model. When the model was built, the risk of stampede accidents in primary and secondary school teaching buildings was assessed by causal reasoning, and the sensitive risk factors were found with sensitivity analysis based on GenIe 2.0. The results show that the occurrence probability of stampede accidents in a teaching building is 0.87%, and strengthening safety management, especially preparation of a comprehensive and effective emergency plan, can significantly reduce the occurrence probability of stampede accidents in teaching buildings.

The Science and Art Of Decision Making 决策的科学与艺术
E. Çepni
Decision makers of today routinely encounter increasingly complex and interrelated problems, preceding the necessity for a large number of significant decisions to be dynamic in nature. Frequently rather than a single decision the requirement of a number of decisions exists, conventionally being interdependent on each other in an environment of progressive change. For thousands of years people have endeavoured to document observations of the environment and surroundings, with the aspiration of comprehending situations, which in turn enable a form of anticipation or prediction of the future. Through the contributions of a range of scientists and philosophers' humanity has affected the achievement of an improved quality of life, commencement of influence on the essence of life and encouragement to attempt to gain even further knowledge through travel to other planets. Without any doubt science is exceptional and dynamic and by far the optimum means of discovering the world and all that it encompasses. What hasn't changed is the curiosity, imagination and intelligence of those doing science [1]. Despite the fact that scientific discoveries and inventions invariably enhance life to a large degree as well as being accredited with expanding the expected lifespan of humans, scientific and technological improvements may equally precipitate alienation, loss of privacy, environmental problems (chemical and electronic waste), and a greater uncertainty or a black swan event. Science is perceived to be subject about knowledge with curiosity lying at the heart of it, differing from technology in that technology is preferably explained as doing. The 19th century scientist Pierre Laplace elevated determinism to a key place in science. He linked determinism and the ability to predict to the very notion of success in science [2]. For technical decisions science is an unrivalled tool to use, however, for managerial, institutional and personal daily life decisions the same recommendation cannot be given. Numerous key systems incorporated in the life of humans exhibit diverse complexities. Markets compromised of various buyers and sellers all categorized in groups participating in mutual funds, economies with hierarchies of workers, departments, firms, and industries; multi-celled organisms consisting of proteins, membranes, organelles, cells, and organs, the internet with users, stations, servers, and websites. Each of these complex systems exhibits a distinctive property called “emergence” roughly described by a phrase “the whole is more than the sum of the actions of the parts [3]. Scientists depend on the law of rationality; however, the fact that emotion habitually dominates humans on innumerable occasions is well recognized.

今天的决策者经常遇到越来越复杂和相互关联的问题,在此之前需要大量的重大决策在本质上是动态的。在不断变化的环境中,许多决策的需求往往是相互依赖的,而不是单个决策。几千年来,人们一直努力记录对环境和周围环境的观察,渴望了解情况,从而能够对未来进行某种形式的预期或预测。通过一系列科学家和哲学家的贡献,人类已经影响到提高生活质量的成就,开始对生命的本质产生影响,并鼓励人们试图通过到其他星球旅行获得更多的知识。毫无疑问,科学是特殊的、动态的,是迄今为止发现世界及其所包含的一切的最佳手段。没有改变的是科学工作者的好奇心、想象力和智慧。尽管科学发现和发明不可避免地在很大程度上延长了人类的预期寿命,但科学和技术的进步同样可能导致疏远、隐私的丧失、环境问题(化学和电子废物),以及更大的不确定性或黑天鹅事件。科学被认为是知识的主体,好奇心是它的核心,与技术的不同之处在于,技术最好被解释为做。19世纪的科学家皮埃尔·拉普拉斯将决定论提升到了科学的关键地位。他将决定论和预测能力与科学成功的概念联系在一起。对于技术决策,科学是一种无可比拟的工具,然而,对于管理、机构和个人日常生活决策,无法给出同样的建议。人类生活中包含的许多关键系统表现出不同的复杂性。由各种买家和卖家组成的市场都被归类为参与共同基金的群体,以及工人、部门、公司和行业等级制的经济体;由蛋白质、膜、细胞器、细胞和器官组成的多细胞生物,有用户、站点、服务器和网站的互联网。这些复杂系统中的每一个都表现出一种被称为“涌现”的独特特性,大致可以用一句话来描述:“整体大于部分行为的总和”。科学家依靠理性法则;然而,情感在无数场合习惯性地支配人类这一事实是众所周知的。也许解决人性问题更有效的方法应该包括破译人性法则。作为理性法则的替代,可以考虑是否更适合科学家使用有限理性法则,这可能会导致科学研究中的激进范式转变。自然科学知识获取的明确成就与理解社会领域动态的相当微小的成功之间的根本差距是与社会系统一致的行为固有的非线性、不稳定性和不确定性。然而,存在一种替代战略来缩小这一差距的可能性是非常可行的。本文旨在说明在科学研究的参与和理解中抛弃理性假设规则,代之以人的行为和情感的正当性。我们的情感自我是我们创造力和激情背后的主要力量,构成了人性。控制自然可能比控制人性更容易。今天,对混沌的研究和系统思维(强调复杂性、网络和组织模式)也出现在自然科学的前沿。人们对可能导致人类文明毁灭甚至地球上生命灭绝的事件感到不安。到2050年,世界人口将达到97亿。同时,迫切需要将生态伦理标准引入科学。决策不仅仅是一门科学;有必要对它的创造性和个性方面进行检查。在技术发展过程中,必须全面分析这些技术的人性、心理和社会学影响。本文的主要目的是表明决策,特别是在不确定性下的决策,部分是科学的,部分是启发式的或艺术的现象。决策的艺术方面不应该被排除在科学之外。

Predicting Link Sign in Online Social Networks based on Social Psychology Theory and Machine Learning Techniques 基于社会心理学理论和机器学习技术的在线社交网络链接符号预测
Sanjay Kumar, Rohit Beniwal, S. Singh, Vipul Gupta
Online social networks provide a great platform for internet users to share their views and ideas. Social media provides a dynamic platform that includes the formation and deformation of connections. Two types of connections, i.e., Positive and Negative, can exist in a social network. Positive connections are a sign of friendship or trust, while negative connections show enmity or distrust. Various applications in several fields have networks containing both positive and negative edges. Reliable prediction of edge sign can greatly influence in recommending friendly relationships while preventing enemy relationships across the network. Prediction of edge signs has been explored previously also. However, we intend to predict the sign of edges based on extracted features of nodes constructed upon theories of social psychology that includes classical balance theory and the status theory. Moreover, we employ emotional information theory and use the combined extracted features from all the theories to analyze networks for better prediction. Our results show that the proposed methodology has obtained significant accuracy when implemented on two real-life datasets, namely Slashdot and Epinions.
在线社交网络为互联网用户提供了一个很好的平台来分享他们的观点和想法。社交媒体提供了一个动态的平台,包括连接的形成和变形。社交网络中可以存在两种类型的联系,即积极的和消极的。积极的联系是友谊或信任的标志,而消极的联系则表现出敌意或不信任。在一些领域的各种应用都有包含正负边的网络。边缘符号的可靠预测对网络中推荐友好关系和防止敌对关系具有重要影响。边缘符号的预测以前也已经被探索过。然而,我们打算基于社会心理学理论(包括经典平衡理论和地位理论)构建的节点提取特征来预测边缘的标志。此外,我们采用情绪信息理论,并使用从所有理论中提取的特征组合来分析网络,以更好地预测。我们的研究结果表明,当在两个现实数据集(即Slashdot和Epinions)上实施时,所提出的方法获得了显着的准确性。

Differential Privacy for Context-Aware Recommender Systems 上下文感知推荐系统的差异隐私
Shuxin Yang, Kaili Zhu, Wenbing Liang
How to prevent the individual privacy from being disclosed and incorporate contextual information into recommendations process is an urgent problem that needs to be solved in recommendation systems. Challenged by the above, a context-aware recommendation method that integrates Differential Privacy and Bayesian Network technologies is proposed. Firstly, in order to alleviate sparsity of the rating matrix, the paper adopts k-means algorithm to cluster items. And then add noises to ratings to protect users' privacy. Finally, the probability that a user likes a certain type of project in contextual information is calculated by Bayesian formula. Experimental evaluations show that the proposed algorithm can provide a stronger privacy protection while improving the accuracy of recommendations.

An Optimized Model Checking Parallel Algorithm Based on CUDA 一种基于CUDA的优化模型检测并行算法
Chaoqun Chu, G. Luo, Mingyang Zhang
With the continuous advancement of the information society, the dependence of hardware and software systems in almost all fields is increasing. Model checking is a method of automatically verifying hardware and software systems in a finite state space. If system does not satisfy the formal formula description, then the system's counterexamples are given and the system's error will be corrected. However, the typical state explosion problem increases its complexity in time and space, which severely limits its applicability. In this paper, an optimized parallel algorithm for searching strongly connected components based on CUDA(FW-BW-CUDA) is proposed, which can effectively accelerate the speed of LTL model checking algorithm. More over, experimental results based on benchmark datasets show that compared with some state-of-the-art model checking algorithms, FW-BW-CUDA performs better in terms of speed in most cases.
随着信息社会的不断进步,几乎所有领域对硬件和软件系统的依赖性都在增加。模型检验是在有限状态空间中对硬件和软件系统进行自动检验的一种方法。如果系统不满足形式公式描述,则给出系统的反例,并对系统的误差进行修正。然而,典型状态爆炸问题在时间和空间上增加了复杂性,严重限制了其适用性。本文提出了一种基于CUDA的强连通组件搜索优化并行算法(FW-BW-CUDA),可有效加快LTL模型检查算法的速度。此外,基于基准数据集的实验结果表明,与一些最先进的模型检查算法相比,FW-BW-CUDA在大多数情况下在速度方面表现更好。

S. Vidhusha, B. Divya, K. Anandan, R. Narayanan, D. Yaamini
Individuals with autism spectrum disorder demonstrate impairments in social functions including difficulties in social interactions, social communication and emotion recognition. They struggle in making eye contact and this hampers their learning due to lack of listening. Virtual reality provides a supportive environment for individuals with autism disorders to learn and practice things safely. In this work, a Virtual reality (VR) platform has been developed which acts as a simulative learning tool to teach and train kids affected with autism spectral disorder. EEG signals of participants during flashcard teaching and VR teaching sessions were acquired and functional connectivity parameters were estimated from the acquired signals. This VR experiment with autistic children indicate that their cognitive ability can be enhanced through constructive teaching by using suitable VR environments. Thus it can be extended for different learning disorders in assisting children to practice things safely without any social fear and in enhancing their interpersonal skills.
自闭症谱系障碍患者表现出社会功能障碍,包括社会互动、社会沟通和情感识别方面的困难。他们很难进行眼神交流,由于缺乏倾听,这阻碍了他们的学习。虚拟现实为自闭症患者提供了一个支持性的环境,让他们安全地学习和练习。在这项工作中,我们开发了一个虚拟现实(VR)平台,作为一个模拟学习工具来教授和训练自闭症谱系障碍儿童。获取被试在抽认卡教学和虚拟现实教学过程中的脑电图信号,并根据所获取的信号估计功能连接参数。本次自闭症儿童的VR实验表明,通过使用合适的VR环境进行建设性的教学,可以提高自闭症儿童的认知能力。因此,它可以扩展到不同的学习障碍,帮助儿童安全地练习事物,没有任何社交恐惧,提高他们的人际交往能力。

Web Insights for National Security: Analysing Participative Online Activity to Interpret Crises 国家安全的网络洞察:分析参与性在线活动以解释危机
Pedro Cárdenas, Georgios Theodoropoulos, B. Obara
Social Media has become the primary communication channel to share feelings and opinions to big audiences. This characteristic is especially important when dealing with a crisis because people use it to send a variety of messages; however, to emphasise or complement what they post, individuals include links to web pages or other web services. Contributing a component to a novel framework for National Security crises analysis and management, this paper focuses on Web Insights as a mechanism that can help to comprehend the nature and state of a crisis. The mechanism analyses web resources and provides insights along three different dimensions: Firstly, the escalation of the crisis over time. Secondly, the interpretation of the information that the main actors have published (Social Networking Services, Information Outlets, Non-Governmental Organisations and Independent Websites). Thirdly, an estimate whether the crisis has turned violent.
社交媒体已经成为向广大受众分享感受和观点的主要沟通渠道。这一特征在处理危机时尤为重要,因为人们用它来传递各种信息;然而,为了强调或补充他们发布的内容,个人会包含指向网页或其他网络服务的链接。本文为国家安全危机分析和管理的新框架提供了一个组成部分,将Web Insights作为一种有助于理解危机性质和状态的机制。该机制分析网络资源,并从三个不同的维度提供见解:首先,危机随着时间的推移而升级。其次,对主要参与者发布的信息(社交网络服务、信息渠道、非政府组织和独立网站)的解释。第三,对危机是否演变为暴力的估计。
