Junjie Bai, Jun Peng, Jinliang Shi, Dedong Tang, Ying Wu, Jianqing Li, Kan Luo
As hot topics in current research, music emotion recognition (MER) have been addressed by different disciplines such as physiology, psychology, musicology, cognitive science, etc. In this paper, music emotions was modeled as continuous variables composed of valence and arousal values (VA values) based on Valence-Arousal model, and MER is formulated as a regression problem. 548 dimensions of music features were extracted and selected. The support vector regression, random forest regression and regression neural networks were adopted to recognize music emotion. Experimental results show that these regression algorithms achieved good regression effect. The optimal R2 statistics of values of VA values are 29.3% and 62.5%, which are achieved respectively by RFR and SVR in Relief feature space.

Experiments on the supervised learning algorithm for formal concept elicitation by cognitive robots 认知机器人形式概念启发的监督学习算法实验
Omar A. Zatarain, Yingxu Wang
Concept elicitation is a fundamental methodology for knowledge extraction and representation in cognitive robot learning. Traditional machine learning technologies deal with object identification, cluster classification, functional regression, and behavior acquisition. This paper presents a supervised machine knowledge learning methodology for concept elicitation from sample dictionaries in natural languages. Formal concepts are autonomously generated based on collective intention of attributes and collective extension of objects elicited from informal definitions in dictionaries. A system of formal concept generation for a cognitive robot is implemented by the Algorithm of Machine Concept Elicitation (AMCE) in MATLAB. Experiments on machine learning for creating a set of twenty formal concepts reveal that the cognitive robot is able to learn synergized concepts in human knowledge in order to build its own cognitive knowledge base. The results of machine-generated concepts demonstrate that the AMCE algorithm can over perform human knowledge expressions in dictionaries in terms of relevance, accuracy, quantitativeness, and cohesiveness.
概念启发是认知机器人学习中知识提取和表达的基本方法。传统的机器学习技术涉及对象识别、聚类分类、功能回归和行为获取。本文提出了一种基于监督的机器知识学习方法,用于从自然语言样本字典中提取概念。形式概念是基于从字典中的非正式定义中引出的属性的集体意图和对象的集体扩展而自主生成的。利用MATLAB中的机器概念启发算法(AMCE)实现了认知机器人的形式概念生成系统。在机器学习中创建20个形式概念的实验表明,认知机器人能够学习人类知识中的协同概念,以建立自己的认知知识库。机器生成概念的结果表明,AMCE算法在相关性、准确性、定量和内聚性方面优于字典中的人类知识表达。

Hiroaki Koma, Taku Harada, Akira Yoshizawa, H. Iwasaki
Eye movements are well known to express cognitive distraction. Detecting cognitive distraction can help to prevent work-related accidents; thus, it is very useful to detect cognitive distraction using eye movements. Eye movements can be classified into various types. In this paper, we apply an identification-based machine learning algorithm considering eye movement types. We apply Random Forest as the machine learning algorithm. We show the effectiveness of considering eye movement types when applying Random Forest to detect cognitive distraction.

Feature extraction of video using deep neural network 基于深度神经网络的视频特征提取
Yoshihiro Hayakawa, Takanori Oonuma, Hideyuki Kobayashi, Akiko Takahashi, Shinji Chiba, N. M. Fujiki
In deep neural networks, which have been gaining attention in recent years, the features of input images are expressed in a middle layer. Using the information on this feature layer, high performance can be demonstrated in the image recognition field. In the present study, we achieve image recognition, without using convolutional neural networks or sparse coding, through an image feature extraction function obtained when identity mapping learning is applied to sandglass-style feed-forward neural networks. In sports form analysis, for example, a state trajectory is mapped in a low-dimensional feature space based on a consecutive series of actions. Here, we discuss ideas related to image analysis by applying the above method.
在近年来备受关注的深度神经网络中,输入图像的特征在中间层中表达。利用该特征层的信息,可以在图像识别领域展示高性能。在本研究中,我们不使用卷积神经网络或稀疏编码,通过将身份映射学习应用于沙漏式前馈神经网络时获得的图像特征提取函数来实现图像识别。例如,在运动形式分析中,基于一系列连续动作,将状态轨迹映射到低维特征空间中。在这里,我们讨论应用上述方法进行图像分析的相关思想。

Cognitive visual analytics of multi-dimensional cloud system monitoring data 多维云系统监测数据的认知可视化分析
G. Baciu, Yungzhe Wang, Chenhui Li
Hardware virtualization has enabled large scale computational service delivery models with significant cost leverage and has improved resource utilization of cloud computing platforms. This has completely changed the landscape of computing in the last decade. It has enabled very large-scale data analytics through distributed, high performance computing. However, due to the infrastructure complexity, end-users and administrators of cloud platforms can rarely obtain a complete picture of the state of cloud computing systems and data centers. Recent monitoring tools enable users to obtain large amounts of data with respect to many utilization parameters of cloud platforms. However, they often fall short of maximizing the overall insight into the resource utilization dynamics of cloud platforms. Furthermore, existing tools make it difficult to observe large scale patterns making it difficult to learn from the past behavior of cloud system dynamics. New operating platforms for cloud management and service provisioning allow live migration and dynamic resource re-allocation at multiple levels of the hardware virtualization layers. Hence, it has become necessary to provide cognitive visualizing tools for monitoring the activities in an active cloud environment. In this work, we describe a perceptual-based interactive visualization platform that gives users and administrators a cognitive view of cloud computing system dynamics. We define machine states and aggregate states at multiple levels of detail to construct a multiview presentation of the resource utilization according to the scalability and the elasticity features of a cloud computing system.
硬件虚拟化使大规模计算服务交付模型具有显著的成本杠杆,并提高了云计算平台的资源利用率。在过去的十年里,这完全改变了计算机的面貌。它通过分布式、高性能计算实现了非常大规模的数据分析。然而,由于基础设施的复杂性,云平台的最终用户和管理员很少能够获得云计算系统和数据中心状态的完整图景。最近的监测工具使用户能够获得关于云平台的许多利用参数的大量数据。然而,它们往往不能最大限度地全面了解云平台的资源利用动态。此外,现有的工具难以观察大规模的模式,从而难以从云系统动力学的过去行为中学习。用于云管理和服务供应的新操作平台允许在硬件虚拟化层的多个级别上进行实时迁移和动态资源重新分配。因此,有必要提供用于监视活动云环境中的活动的认知可视化工具。在这项工作中,我们描述了一个基于感知的交互式可视化平台,该平台为用户和管理员提供了云计算系统动态的认知视图。根据云计算系统的可伸缩性和弹性特点,在多个细节层次上定义机器状态和聚合状态,构建资源利用的多视图表示。

Kaizhong Zhang
Similarity metric and distance metric are widely used in many research areas and applications. In this paper, for a given similarity metric, we will introduce a family of distance metrics of Minkowski type. We will then show general solutions to construct normalized similarity metric and normalized distance metric from a similarity metric and a distance metric. Applying the general solutions to a given non-negative similarity metric and its induced family of distance metrics, we derive general normalized similarity metrics and normalized distance metrics. Finally we briefly discuss some of the applications of our general similarity and distance metric formulations.

Logic of natural language: Through the eyes of ontological semantics 自然语言的逻辑:本体语义学的视角
Julia Taylor Rayz, V. Raskin
The meat of the paper is a small innovation in Ontological Semantic Technology describing how to calculate weights in text meaning representations. It is reset here as a component of a complex and apparently unprecedented global logic of natural language, a topic that was abortively entertained in the 1960–70s and since then mostly abandoned.

Jingliang Shi, Ying Wu, Lu Liao, Xin-ping Yan, J. Zeng, Rusen Yang
In the iron-making process, the state of burning through point (BTP) is the closure of sintering which is one of the most important parameters in judging the state of sintering. Based on the PSO (Particle Swarm Optimization)-inversion soft-sensing method, the BTP which can not be directly measured in the iron-making process is soft-sensed in this paper. Firstly, the principle of sintering is studied. Four parameters are employed to forecast the BTP, including the suction pressure of main chimney flue, air input, velocity of sintering machine and ignition temperature. And then, a prediction model using PSO is established. At last, the model is applied to production process. It is proved to be effective.

A copula based method for fish species classification 一种基于交配体的鱼类分类方法
Raj Singh Dhawal, Liang Chen
The proposed work develops a method for classification of the species of a fish given in an image, which is a sub-ordinate level classification problem. Sub-ordinate classification is complex as it relies on identifying the notable distinction among the part level characteristics of subjects rather than relying on presence or absence of parts for classification, as done in basic level categorization. Fish image categorization is unique and challenging as the images of same fish species can show significant differences in the fish's attributes when taken in different conditions. Our approach analyses the local patches of images, cropped based on specific body parts, and hence keep comparison more specific to grab more finer details rather than comparing global postures. We have used state-of-the-art multidimensional image descriptor HOG (Histogram of Oriented Gradients) and, colour histograms to create representative feature vectors; feature vectors are summarized using Copula theory which has not been used in many applications in analysing multi-dimensional space despite being one of the most used tools to analyse bivariate data from complex industries like finance and medical science. Our method is very simple yet we have matched the classification accuracy of other proposed complex work for such problems.
本文提出了一种对图像中给定的鱼的种类进行分类的方法,这是一个从属层次的分类问题。从属分类是复杂的,因为它依赖于识别主体部分层次特征之间的显著区别,而不是像基本层次分类那样依赖于是否存在部分进行分类。鱼类图像分类具有独特性和挑战性,因为同一鱼类在不同条件下拍摄的图像可能显示出鱼类属性的显着差异。我们的方法分析图像的局部补丁,根据特定的身体部位裁剪,因此保持比较更具体,以获取更精细的细节,而不是比较全局姿势。我们使用了最先进的多维图像描述符HOG(定向梯度直方图)和颜色直方图来创建代表性特征向量;利用Copula理论对特征向量进行了总结,尽管Copula理论是分析金融和医学等复杂行业中最常用的二元数据的工具之一,但在分析多维空间方面并没有得到很多应用。我们的方法非常简单,但我们已经匹配了其他提出的复杂工作对这类问题的分类精度。
