Space syntax and time distance based analysis on the influences of the subways to the pubic traffic accessibility in Nanchang city 基于空间句法和时间距离的南昌市地铁对公共交通可达性影响分析
Handan Zhang, B. Hu
Based on the database of public transportation network in Nanchang, this paper evaluates the accessibility of urban public transportation by using space syntax and time distance methods. Through the calculation of the space syntax index, accessibility index and the time cost of each node, the results show that the accessibility of road intensive area and urban centers is higher than other regions, the convenience of subway line is better than bus lines, and the influence of a road along the subway is more significant than that of other regions. The control value of the whole public transit network remains stable, the time cost of urban traffic has been significantly improved with the completion of the metro line 2, the average saving travel time is about 4min, and the transit time between public transportation sites is also reduced with the constructions of subway lines. The evaluations of the pubic traffic accessibility in Nanchang city have the consistent conclusions according to space syntax and time distance methods.
基于南昌市公共交通网络数据库,采用空间句法法和时间距离法对城市公共交通可达性进行评价。通过对各节点的空间句法指数、可达性指数和时间成本的计算,结果表明:道路密集区和城市中心的可达性高于其他区域,地铁线路的便利性优于公交线路,地铁沿线道路的影响比其他区域更显著。整个公共交通网络的控制值保持稳定,随着地铁2号线的建成,城市交通的时间成本得到了显著提高,平均节省出行时间约为4min,公共交通站点之间的过境时间也随着地铁线路的建设而缩短。运用空间句法法和时间距离法对南昌市公共交通可达性进行评价,得出了一致的结论。

Designing fuzzy apparatus to model dyslexic individual symptoms for clinical use 设计用于临床的模糊模型来模拟阅读困难的个体症状
Tereza Parilová, E. Hladká, P. Říha
Along with the discovery of new facts and the development of new technologies and methodologies, more and more definitions and specifications emerge. The quantity of these emergences, however, can lead to paradoxical contradictions, which obscure borders. Often, we see this phenomenon of vagueness within natural language or non-exact topics. Fuzzy principles are therefore applied in wide range of (not only) scientific areas. In applied technical science, a user model based on interface and human computer cooperation meets such fuzzy borders. So, why not use it in assistive technology models? Fuzzy deals from its nature with linguistic variables and such variables are being transformed from numbers to expressions on predefined scales. Dyslexia is a neurobiological cognitive based disorder and ideal for (neuro) fuzzy computational modeling for many reasons. This paper describes the idea and process of using the fuzzy approach for obtaining information about individual problems of dyslexic users and differentiating between the type(s) of dyslexic user model he or she may belong to. Such information may serve for further clinical and psychological studies of dyslexia and linguistic based problems.
随着新事实的发现和新技术、新方法的发展,出现了越来越多的定义和规范。然而,这些出现的数量可能导致自相矛盾的矛盾,从而模糊了边界。我们经常在自然语言或不精确的话题中看到这种模糊现象。因此,模糊原理被广泛应用于(不仅仅是)科学领域。在应用技术科学中,基于界面和人机协作的用户模型满足这种模糊边界。那么,为什么不在辅助技术模型中使用它呢?模糊从本质上处理语言变量,这些变量在预定义的尺度上从数字转换为表达式。阅读障碍是一种基于神经生物学的认知障碍,由于许多原因,它是神经模糊计算模型的理想选择。本文描述了使用模糊方法获取有关阅读困难用户个体问题的信息,并区分他或她可能属于的阅读困难用户模型类型的思想和过程。这些信息可以为进一步的临床和心理研究阅读障碍和语言基础问题服务。

Rong Fan, Wenxin Hu
Deep learning techniques have become the state-of-the-art approach for classification in artificial intelligence, and applied in many widespread subjects. Deep Belief Networks (DBNs) are one of the most successful models. DBNs consist of many layers of hidden factors along with a greedy layer-wise unsupervised learning algorithm. In our paper, we brought forward an approach to face recognition based on dropout DBNs, which made good performances on small training sets.

Exploiting semantic knowledge base for patent retrieval 利用语义知识库进行专利检索
Feng Wang, Lanfen Lin
Patent retrieval is considered as recall-oriented retrieval that aims to find all relevant patent documents for a patent query. However, current methods encounter the term mismatch problem, because of the frequent use of nonstandard technical terms in patent documents. In order to deal with this problem, we propose a new patent query expansion approach by exploiting semantic knowledge base, which can enrich the query with semantically related concepts. Concretely, to understand the query semantics, we present the WordNet and Wikipedia-based expansion algorithms enhancing the initial query. We further provide the combination strategy to execute query and obtain retrieval results. Experiments are performed based on Java environment using the CLEF-IP collection. Results show that the performance of our approach is significantly better than other state-of-the-art approaches.
专利检索被认为是一种面向回忆的检索,其目的是为专利查询找到所有相关的专利文献。然而,由于专利文献中经常使用非标准的技术术语,目前的方法遇到术语不匹配的问题。为了解决这一问题,我们提出了一种利用语义知识库的专利查询扩展方法,该方法可以用语义相关的概念来丰富专利查询。具体来说,为了理解查询语义,我们提出了基于WordNet和维基百科的扩展算法来增强初始查询。我们进一步提供了执行查询和获取检索结果的组合策略。利用CLEF-IP集合在Java环境下进行了实验。结果表明,我们的方法的性能明显优于其他最先进的方法。

Analyst intuition based Hidden Markov Model on high speed, temporal cyber security big data 基于分析师直觉的隐马尔可夫模型在高速、瞬时网络安全大数据中的应用
Teoh Teik Toe, Y. Nguwi, Y. Elovici, Ngai-Man Cheung, W. Ng
Hidden Markov Models (HMM) are probabilistic models that can be used for forecasting time series data. It has seen success in various domains like finance [1-5], bioinformatics [6-8], healthcare [9-11], agriculture [12-14], artificial intelligence[15-17]. However, the use of HMM in cyber security found to date is numbered. We believe the properties of HMM being predictive, probabilistic, and its ability to model different naturally occurring states form a good basis to model cyber security data. It is hence the motivation of this work to provide the initial results of our attempts to predict security attacks using HMM. A large network datasets representing cyber security attacks have been used in this work to establish an expert system. The characteristics of attacker's IP addresses can be extracted from our integrated datasets to generate statistical data. The cyber security expert provides the weight of each attribute and forms a scoring system by annotating the log history. We applied HMM to distinguish between a cyber security attack, unsure and no attack by first breaking the data into 3 cluster using Fuzzy K mean (FKM), then manually label a small data (Analyst Intuition) and finally use HMM state-based approach. By doing so, our results are very encouraging as compare to finding anomaly in a cyber security log, which generally results in creating huge amount of false detection.
隐马尔可夫模型(HMM)是一种概率模型,可用于预测时间序列数据。它在金融[1-5]、生物信息学[6-8]、医疗保健[9-11]、农业[12-14]、人工智能[15-17]等各个领域都取得了成功。然而,迄今为止,HMM在网络安全领域的应用寥寥无几。我们相信HMM的预测性、概率性以及它对不同自然状态的建模能力为网络安全数据的建模奠定了良好的基础。因此,这项工作的动机是提供我们尝试使用HMM预测安全攻击的初步结果。在此工作中,使用了代表网络安全攻击的大型网络数据集来建立专家系统。从我们的集成数据集中提取攻击者的IP地址特征,生成统计数据。网络安全专家提供每个属性的权重,并通过注释日志历史形成评分系统。我们首先使用模糊K均值(FKM)将数据分成3个聚类,然后手动标记小数据(分析师直觉),最后使用基于HMM状态的方法,应用HMM来区分网络安全攻击、不确定攻击和无攻击。通过这样做,与在网络安全日志中发现异常相比,我们的结果非常令人鼓舞,因为网络安全日志通常会导致大量的错误检测。

EEG signal analysis of patients with obstructive sleep apnea syndrome (OSAS) using power spectrum and fuzzy entropy 基于功率谱和模糊熵的阻塞性睡眠呼吸暂停综合征(OSAS)脑电信号分析
Szu-Yu Lin, Yu-Te Wu, W. Mao, Po-Shan Wang
Sleep is important for the restoration and renewal of the human body. Obstructive sleep apnea syndrome (OSAS), which is caused by repetitive episodes of partial or complete upper airway obstruction during sleep, is the most common type of sleep apnea. The sleep electroencephalogram (EEG) analysis has been an important tool to investigate brain activity. In this study, we used the spectral analysis and fuzzy entropy to analyze the EEG signals collected from the OSAS patients and normal control. Results obtained from the EEG power spectrum and fuzzy entropy with and without principal component analysis (PCA) process were used as the features and fed into four different classifiers, namely, linear Support Vector Machines (SVM), Liner Discriminant Analysis (LDA), subspace k-nearest neighbor (k-NN) and subspace discriminant analysis, to differentiate these two groups. Our results demonstrated that the feature resulted from power spectrum with PCA process and subspace discriminate method using 5-fold cross-validation produces the superior classification rate which is 89 ± 3.74%.
睡眠对人体的恢复和更新很重要。阻塞性睡眠呼吸暂停综合征(OSAS)是最常见的睡眠呼吸暂停类型,是由睡眠期间部分或完全上呼吸道阻塞反复发作引起的。睡眠脑电图(EEG)分析已成为研究大脑活动的重要工具。在本研究中,我们采用频谱分析和模糊熵对OSAS患者和正常人的脑电图信号进行分析。采用主成分分析(PCA)和不采用主成分分析(PCA)的脑电功率谱和模糊熵结果作为特征,分别输入线性支持向量机(SVM)、线性判别分析(LDA)、子空间k近邻(k-NN)和子空间判别分析四种不同的分类器进行分类。结果表明,基于主成分分析和5倍交叉验证的子空间判别方法得到的功率谱特征的分类率为89±3.74%。

Infrared image change detection of substation equipment in power system using random forest 基于随机森林的电力系统变电设备红外图像变化检测
Hua Yang, Jipu Gao, Changbao Xu, Zheng Long, Weigang Feng, S. Xiong, Shuaiwei Liu, Shan Tan
Early detection of equipment faults plays a crucial role in power system, and automatic change detection of working status of an equipment is an efficient tool for this purpose. In this study, we proposed a novel method to automatically detect temperature change in local region of a substation equipment in power system using bi-temporal infrared images. We considered the change detection as two-class classification problem, and a supervised machine learning algorithm — Random Forest (RF) — was used for forecasting change trend. Various features were extracted from two temporal images for change detection. The features we extracted include gray-level, weighted intensity mean, RGB, LBP, gray-level histogram, and texture originating from the grayscale images and color images of the bi-temporal infrared images of the substation equipment. Cross validation was used to evaluate the robustness of these extracted features. Due to the existence of environmental noise, there are isolated detection points in the change detection results. In order to remove these isolated noise points and improve detection accuracy, we performed a morphological filtering on the detection results. Evaluation indexes such as Dice Similarity Index (DSI), kappa coefficient were used to evaluate the detection performance. Four classical change detection methods i.e. Image Differencing, Image Ratioing, Change vector analysis (CVA) and Principal Component Analysis (PCA) were tested for comparison purpose. Experimental results demonstrated that the proposed algorithm outperformed significantly these classical methods.
早期发现设备故障在电力系统中起着至关重要的作用,而设备工作状态变化自动检测是实现这一目标的有效工具。在这项研究中,我们提出了一种利用双时相红外图像自动检测电力系统中变电站设备局部温度变化的新方法。我们将变化检测视为两类分类问题,并使用有监督机器学习算法随机森林(Random Forest, RF)来预测变化趋势。从两幅时间图像中提取各种特征进行变化检测。从变电站设备双时相红外图像的灰度图像和彩色图像中提取的特征包括灰度、加权强度均值、RGB、LBP、灰度直方图和纹理。交叉验证用于评估这些提取特征的鲁棒性。由于环境噪声的存在,变化检测结果中存在孤立的检测点。为了去除这些孤立的噪声点,提高检测精度,我们对检测结果进行了形态学滤波。采用Dice Similarity Index (DSI)、kappa系数等评价指标对检测性能进行评价。对四种经典的变化检测方法即图像差分、图像比例、变化向量分析(CVA)和主成分分析(PCA)进行了比较。实验结果表明,该算法明显优于这些经典方法。

The efficiency of the new method is proven on the given example of control system synthesis for mobile robot.","PeriodicalId":236093,"journal":{"name":"2017 13th International Conference on Natural Computation, Fuzzy Systems and Knowledge Discovery (ICNC-FSKD)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128125119","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}

Convolutional neural networks for class attendance 卷积神经网络的课堂出勤率
Zhao Pei, Hai-Dong Shang, Yi Su, Miao Ma, Yali Peng
Conventionally, students attendance records are taken manually by teachers through roll calling in the class. It is time-consuming and prone to errors. Moreover, records of attendance are difficult to handle and preserve for the long-term. In this paper, we propose a more conveniently method of attendance statistics, which achieved through the Convolutional Neural Network (CNN). The traditional method of face recognition, such as Eigenface, is sensitive to lighting, noise, gestures, expressions and etc. Hence, we utilize CNN to implement face recognition, in order to reduce the effect of environmental change on experimental results. In addition, CNN is a method which needs lots of data for training. To resolve the problem, we design a new method to collect face data which can get lots of face data quickly and conveniently.
传统上,学生的出勤记录是由老师在课堂上通过点名来手工记录的。它既耗时又容易出错。此外,考勤记录很难处理和长期保存。在本文中,我们提出了一种更方便的考勤统计方法,该方法通过卷积神经网络(CNN)实现。传统的人脸识别方法,如特征脸,对光线、噪声、手势、表情等都很敏感。因此,我们利用CNN来实现人脸识别,以减少环境变化对实验结果的影响。另外,CNN是一种需要大量数据进行训练的方法。为了解决这个问题,我们设计了一种新的人脸数据采集方法,可以快速方便地获取大量的人脸数据。
