A novel method for document summarization using Word2Vec 一种基于Word2Vec的文档摘要新方法
Zhibo Wang, Long Ma, Yanqing Zhang
Texting mining is a process to extract useful patterns and information from large volume of unstructured text data. Unlike other quantitative data, unstructured text data cannot be directly utilized in machine learning models. Hence, data pre-processing is an essential step to remove vague or redundant data such as punctuations, stop-words, low-frequency words in the corpus, and re-organize the data in a format that computers can understand. Though existing approaches are able to eliminate some symbols and stop-words during the pre-processing step, a portion of words are not used to describe the documents' topics. These irrelevant words not only waste the storage that lessen the efficiency of computing, but also lead to confounding results. In this paper, we propose an optimization method to further remove these irrelevant words which are not highly correlated to the documents' topics. Experimental results indicate that our proposed method significantly compresses the documents, while the resulting documents remain a high discrimination in classification tasks; additionally, storage is greatly reduced according to various criteria.
文本挖掘是从大量的非结构化文本数据中提取有用模式和信息的过程。与其他定量数据不同,非结构化文本数据不能直接用于机器学习模型。因此,数据预处理是去除语料库中标点、停顿词、低频词等模糊或冗余的数据,并以计算机可以理解的格式重新组织数据的必要步骤。虽然现有的方法能够在预处理过程中消除一些符号和停止词,但仍有一部分词没有被用来描述文档的主题。这些不相关的词不仅浪费了存储空间,降低了计算效率,而且还会导致混淆结果。在本文中,我们提出了一种优化方法来进一步去除这些与文档主题不高度相关的无关词。实验结果表明,本文提出的方法在有效压缩文档的同时,在分类任务中保持了较高的识别率;此外,根据各种标准,存储空间大大减少。

Algorithms for determining semantic relations of formal concepts by cognitive machine learning based on concept algebra 基于概念代数的形式概念语义关系的认知机器学习算法
M. Valipour, Yingxu Wang, Omar A. Zatarain, M. Gavrilova
It is recognized that the semantic space of knowledge is a hierarchical concept network. This paper presents theories and algorithms of hierarchical concept classification by quantitative semantic relations via machine learning based on concept algebra. The equivalence between formal concepts are analyzed by an Algorithm of Concept Equivalence Analysis (ACEA), which quantitatively determines the semantic similarity of an arbitrary pair of formal concepts. This leads to the development of the Algorithm of Relational Semantic Classification (ARSC) for hierarchically classify any given concept in the semantic space of knowledge. Experiments applying Algorithms ACEA and ARSC on 20 formal concepts are successfully conducted, which encouragingly demonstrate the deep machine understanding of semantic relations and their quantitative weights beyond human perspectives on knowledge learning and natural language processing.
认识到知识的语义空间是一个层次概念网络。本文提出了基于概念代数的机器学习的定量语义关系分层概念分类的理论和算法。采用概念等价分析算法(ACEA)对形式概念之间的等价性进行分析,该算法定量地确定任意一对形式概念之间的语义相似度。这导致了关系语义分类算法(ARSC)的发展,该算法可以对知识语义空间中的任何给定概念进行分层分类。应用算法ACEA和ARSC在20个形式概念上成功进行了实验,这令人鼓舞地展示了机器对语义关系及其定量权重的深度理解,超越了人类在知识学习和自然语言处理方面的观点。

Extracting time-oriented relationships of nutrients to losing body fat mass using inductive logic programming 利用归纳逻辑程序设计提取营养素与减少体脂量的时间导向关系
Sho Ushikubo, K. Kanamori, H. Ohwada
This study was performed to extract rules for reducing body fat mass so as to prevent lifestyle-related diseases. Lifestyle-related diseases have been increasing in Japan, even among younger people. Body fat mass is related to lifestyle-related diseases. Hence, finding rules for reducing body fat mass is very meaningful. We obtained lifestyle time-series data on five male subjects who are in their 20s and not obese. The data includes the amount of body fat mass of each subject and a variety of features such as sleep, exercise, and nutrient intake. We used Inductive Logic Programming (ILP) to apply this data because ILP can more flexibly learn rules than other machine-learning methods. As a result of applying the data to ILP, our ILP system successfully extracted rules of time-oriented relationships of nutrients to decrease body fat mass based on limited data. Intake of various nutrients one day and two days prior was effective in reducing body fat mass. Moreover, we determined that nutrients related to losing body fat mass include vitamin B2, pantothenic acid, fat, vitamin B1, and biotin.
本研究旨在提取减少体脂量的规律,从而预防与生活方式有关的疾病。在日本,与生活方式有关的疾病一直在增加,甚至在年轻人中也是如此。身体脂肪量与生活方式相关的疾病有关。因此,寻找减少身体脂肪量的规则是非常有意义的。我们获得了五名20多岁、不肥胖的男性受试者的生活方式时间序列数据。这些数据包括每个受试者的体脂量以及睡眠、运动和营养摄入等各种特征。我们使用归纳逻辑编程(ILP)来应用这些数据,因为ILP可以比其他机器学习方法更灵活地学习规则。将数据应用到ILP中,我们的ILP系统成功地在有限的数据基础上提取了营养素的时间导向关系规则,以减少体脂量。在一天前和两天前摄入各种营养物质对减少体脂量是有效的。此外,我们确定了与减少身体脂肪量相关的营养素包括维生素B2、泛酸、脂肪、维生素B1和生物素。

Modeling chunking effects on learning and performance using the Computational-Unified Learning Model (C-ULM): A multiagent cognitive process model 使用计算统一学习模型(C-ULM)建模分块对学习和绩效的影响:一个多智能体认知过程模型
D. Shell, Leen-Kiat Soh, Vlad Chiriacescu
Chunking has emerged as a basic property of human cognition. Computationally, chunking has been proposed as a process for compressing information also has been identified in neural processes in the brain and used in models of these processes. Our purpose in this paper is to expand understanding of how chunking impacts both learning and performance using the Computational-Unified Learning Model (C-ULM) a multi-agent computational model. Chunks in C-ULM long-term memory result from the updating of concept connection weights via statistical learning. Concept connection weight values move toward the accurate weight value needed for a task and a confusion interval reflecting certainty in the weight value is shortened each time a concept is attended in working memory and each time a task is solved, and the confusion interval is lengthened when a chunk is not retrieved over a number of cycles and each time a task solution attempt fails. The dynamic tension between these updating mechanisms allows chunks to come to represent the history of relative frequency of co-occurrence for the concept connections present in the environment; thereby encoding the statistical regularities in the environment in the long-term memory chunk network. In this paper, the computational formulation of chunking in the C-ULM is described, followed by results of simulation studies examining impacts of chunking versus no chunking on agent learning and agent effectiveness. Then, conclusions and implications of the work both for understanding human learning and for applications within cognitive informatics, artificial intelligence, and cognitive computing are discussed.
分块处理已经成为人类认知的一种基本属性。在计算上,分块已被提出作为一种压缩信息的过程,也已在大脑的神经过程中被确定并用于这些过程的模型中。我们在本文中的目的是使用计算统一学习模型(C-ULM)一种多智能体计算模型来扩展对分块如何影响学习和性能的理解。C-ULM长时记忆中的块是通过统计学习对概念连接权值的更新而产生的。概念连接权重值向任务所需的准确权重值移动,每次在工作记忆中参与一个概念和每次解决一个任务时,反映权重值确定性的混淆间隔就会缩短,当一个块在多个周期内没有被检索时,每次任务解决尝试失败时,混淆间隔就会延长。这些更新机制之间的动态张力允许块来代表环境中存在的概念连接的共现相对频率的历史;从而将环境中的统计规律编码在长时记忆块网络中。本文描述了C-ULM中分块的计算公式,然后给出了分块与不分块对智能体学习和智能体有效性的影响的模拟研究结果。然后,讨论了本研究对理解人类学习以及在认知信息学、人工智能和认知计算中的应用的结论和意义。

Hebbian learning and the LMS algorithm Hebbian学习和LMS算法
B. Widrow
Hebbian learning is one of the fundamental premises of neuroscience. The LMS (least mean square) algorithm of Widrow and Hoff is the world's most widely used learning algorithm. Hebbian learning is unsupervised. LMS learning is supervised. However, a form of LMS can be constructed to perform unsupervised learning and to implement Hebbian learning. Combining the two paradigms creates a new unsupervised learning algorithm that has practical engineering applications and provides insight into learning in living neural networks. A fundamental question is, how does learning take place in living neural networks? The learning algorithm practiced by nature at the neuron and synapse level may well be the Hebbian-LMS algorithm.
Hebbian学习是神经科学的基本前提之一。Widrow和Hoff的LMS(最小均方)算法是目前世界上应用最广泛的学习算法。Hebbian学习是无监督的。LMS学习是有监督的。然而,可以构造一种形式的LMS来执行无监督学习和实现Hebbian学习。结合这两种范式,创造了一种新的无监督学习算法,具有实际的工程应用,并为活体神经网络的学习提供了见解。一个基本的问题是,学习是如何在活的神经网络中发生的?自然界在神经元和突触水平上的学习算法很可能是Hebbian-LMS算法。

A key issue of semantics of information 信息语义的一个关键问题
L. Zadeh
In his epoch-making work on information theory, Shannon defended information in terms of entropy. Entropy-based definitions of information relate to quantity of information, but not to its meaning. Subsequent attempts to introduce semantics into information theory have made some progress but fell short of having a capability to deal with information described in natural language. This paper is aimed that of laying information for the theory which has this capability, call it a theory of semantics information (TSI). TSI is centered on a concept which plays a key role in human intelligence — A concept whose basic importance has long been and continues to be unrecognized — The concept of a restriction is pervasive in human cognition. Restrictions underlie the remarkable human ability to reason and make rational decisions in an environment of imprecision, uncertainty and incompleteness of information. Such environments are the norm in the real-world. Such environments have the traditional logical systems that become dysfunctional. There are many applications in which semantics of information plays an important role. Among such applications are: machine translation, summarization, search and decision-making under uncertainty. Informally, a restriction on a specified (focal) variable, X, written as R (X), is a statement which is a carrier of information about the values which X can take. Typically, restrictions are described in natural language. Example. X = length of time it takes to drive from Berkeley to SF Airport; R(X) = usually it takes about 90 minutes to drive from Berkeley to SF Airport. In adverse weather it may take close to 2 hours. An important issue in TSI is computation with restrictions. TSI opens the door to modes of computation in which approximation is accepted. Acceptance of approximate computations takes the calculus of restrictions (CR) into uncharted territory.
在他划时代的信息论著作中,香农从熵的角度为信息辩护。基于熵的信息定义与信息的数量有关,但与信息的含义无关。随后将语义学引入信息论的尝试取得了一些进展,但缺乏处理用自然语言描述的信息的能力。本文旨在为具有这种能力的理论提供信息,称之为语义信息理论(TSI)。TSI的核心是一个在人类智力中起关键作用的概念,这个概念的基本重要性一直没有被认识到,而且一直没有被认识到。限制的概念在人类认知中无处不在。限制是人类在信息不精确、不确定和不完整的环境中进行推理和做出理性决定的非凡能力的基础。这样的环境是现实世界中的常态。在这样的环境中,传统的逻辑系统变得不正常。在许多应用中,信息语义起着重要的作用。这些应用包括:机器翻译、摘要、搜索和不确定决策。非正式地,对指定(焦点)变量X的限制,写成R (X),是一个声明,它是关于X可以取的值的信息载体。通常,限制是用自然语言描述的。的例子。X =从伯克利开车到旧金山机场所需的时间;R(X) =从伯克利开车到SF机场通常需要90分钟左右。在恶劣的天气下,可能需要近2个小时。TSI中的一个重要问题是有限制的计算。TSI为接受近似计算模式打开了大门。接受近似计算将限制演算(CR)带入了未知的领域。

Quantum cognitive computation by CICT CICT的量子认知计算
R. Fiorini
We show and discuss how computational information conservation theory (CICT) can help us to develop even competitive advanced quantum cognitive computational systems towards deep computational cognitive intelligence. CICT new awareness of a discrete HG (hyperbolic geometry) subspace (reciprocal space, RS) of coded heterogeneous hyperbolic structures, underlying the familiar Q Euclidean (direct space, DS) system surface representation can open the way to holographic information geometry (HIG) to recover lost coherence information in system description and to develop advanced quantum cognitive systems. This paper is a relevant contribution towards an effective and convenient “Science 2.0” universal computational framework to achieve deeper cognitive intelligence at your fingertips and beyond.

A feature selection framework based on supervised data clustering 一种基于监督数据聚类的特征选择框架
Hongzhi Liu, Bin Fu, Zhengshen Jiang, Zhonghai Wu, D. Hsu
Feature selection is an important step for data mining and machine learning to deal with the curse of dimensionality. In this paper, we propose a novel feature selection framework based on supervised data clustering. Instead of assuming there only exists low-order dependencies between features and the target variable, the proposed method directly estimates the high-dimensional mutual information between a candidate feature subset and the target variable through supervised data clustering. In addition, it can automatically determine the number of features to be selected instead of manually setting it in a prior. Experimental results show that the proposed method performs similar or better compared with state-of-the-art feature selection methods.
特征选择是数据挖掘和机器学习处理维数诅咒的重要步骤。本文提出了一种新的基于监督数据聚类的特征选择框架。该方法不假设特征与目标变量之间只存在低阶依赖关系,而是通过监督数据聚类直接估计候选特征子集与目标变量之间的高维互信息。此外,它可以自动确定要选择的特征的数量,而不是手动设置它在一个事先。实验结果表明,与现有的特征选择方法相比,该方法具有相似或更好的性能。

In this paper, we propose a novel feature selection framework based on supervised data clustering. Instead of assuming there only exists low-order dependencies between features and the target variable, the proposed method directly estimates the high-dimensional mutual information between a candidate feature subset and the target variable through supervised data clustering. In addition, it can automatically determine the number of features to be selected instead of manually setting it in a prior. Experimental results show that the proposed method performs similar or better compared with state-of-the-art feature selection methods.","PeriodicalId":135701,"journal":{"name":"2016 IEEE 15th International Conference on Cognitive Informatics & Cognitive Computing (ICCI*CC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132719135","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}

On cognitive foundations of big data science and engineering 大数据科学与工程的认知基础
Yingxu Wang
Big data are one of the representative phenomena of the information era of human societies. A basic study on the cognitive foundations of big data science is presented with a coherent set of general principles and analytic methodologies for big data manipulations. It leads to a set of mathematical theories that rigorously describe the general patterns of big data across pervasive domains in sciences, engineering, and societies. A significant finding towards big data science is that big data systems in nature are a recursive n-dimensional typed hyperstructure (RNTHS). The fundamental topological property of big data system enables the inherited complexities and unprecedented challenges of big data to be formally dealt with as a set of denotational mathematical operations in big data engineering. The cognitive relationship and transformability between data, information, knowledge, and intelligence are formally revealed towards big data science.
大数据是人类社会信息时代的代表性现象之一。对大数据科学的认知基础进行了基础研究,提出了一套连贯的大数据操作的一般原则和分析方法。它导致了一组数学理论,这些理论严格地描述了科学、工程和社会中普遍存在的大数据的一般模式。大数据科学的一个重要发现是,大数据系统本质上是一个递归的n维型超结构(RNTHS)。大数据系统的基本拓扑特性使得大数据的复杂性和前所未有的挑战在大数据工程中被形式化地处理为一组表示数学运算。面向大数据科学,数据、信息、知识、智能之间的认知关系和可转化性被正式揭示。
