The need to quantify aleatory and epistemic uncertainties has been widely recognized in the engineering applications. Aleatory uncertainty arises from inherent randomness, whereas epistemic uncertainty is due to the lack of knowledge. Traditionally uncertainty has been quantified by probability measures and the two uncertainty components are not readily differentiated. Intervals naturally capture the systematic error during data acquisition. We develop a new feature extraction and back propagation neural network in the context of generalized interval theory, where all parameters are in the form of a generalized interval. Calculation of generalized interval based on the Kaucher arithmetic is greatly simplified in this application. To demonstrate the new framework, this paper provides a case study of recognizing the cutting states in the manufacturing process. The stable, transition, and chatter state states are recognized by the generalized back propagation neural network (GBPNN) model. The results show that the proposed method has a good recognition performance.
在工程应用中,对确定性和认识性不确定性进行量化的必要性已得到广泛认可。选择性的不确定性源于固有的随机性,认知的不确定性源于知识的缺乏。传统上,不确定性是通过概率度量来量化的,两个不确定性成分不易区分。间隔自然地捕获了数据采集过程中的系统误差。在广义区间理论的背景下,我们开发了一种新的特征提取和反向传播神经网络,其中所有参数都以广义区间的形式存在。该应用极大地简化了基于Kaucher算法的广义区间的计算。为了演示新框架,本文提供了一个制造过程中切削状态识别的案例研究。利用广义反向传播神经网络(GBPNN)模型对系统的稳定态、过渡态和颤振态进行识别。结果表明,该方法具有良好的识别性能。

Towards Service Composition for Consuming Linked Data: A Failure Perspective 面向消费关联数据的服务组合:失败视角
Pub Date : 2013-11-24 DOI: 10.1109/MICAI.2013.23

Service composition can be considered as a Linked Data model due to the way that each one of the services that make up the composition is structured. For doing this, a service composer is required in order to evaluate the input and output data of various web-distributed services for linking them. These links can be analyzed from a quality perspective in which a service may fail when it does not fulfill the requirements that satisfy the linking conditions. Therefore, these conditions are analyzed from two points of view: 1) service availability and, 2) the handling of composer's beliefs. The latter refers to the fact that a service must not consider only two types of data to perform links, it should consider also the value of the instances, taking into account a same context. This work presents a new approach for the consumption of Linked Data in a service composition environment which uses as reference those links which have less probability of failing, selecting those services that can reduce the risk of a composition failure.
由于组成组合的每个服务都是结构化的,因此可以将服务组合视为关联数据模型。为此,需要一个服务编写器来评估各种web分布式服务的输入和输出数据,以便链接它们。可以从质量的角度分析这些链接,在质量的角度中,当服务没有满足满足链接条件的需求时,它可能会失败。因此,本文从两个角度对这些条件进行了分析:1)服务的可用性和2)作曲家信念的处理。后者指的是这样一个事实,即服务不能只考虑两种类型的数据来执行链接,它还应该考虑实例的值,考虑相同的上下文。这项工作提出了一种在服务组合环境中使用关联数据的新方法,该方法使用那些失败可能性较小的链接作为参考,选择那些可以降低组合失败风险的服务。

Improve the Automatic Summarization of Arabic Text Depending on Rhetorical Structure Theory 运用修辞结构理论改进阿拉伯语文本自动摘要
Pub Date : 2013-11-24 DOI: 10.1109/MICAI.2013.35
A. Ibrahim, T. Elghazaly
This paper uses a semantic technique by adopting a Rhetorical Structure Theory (RST) for summarization purpose, to discover the most significant paragraphs based on functional and semantic criteria. However, the quality of RST summarization suffers when dealing with large documents. This paper proposes a new hybrid summarization model for Arabic text, which mingles two sub-models: The first sub-model produces a primary summary by using Rhetorical Structure Theory for identifying a range of the most significant parts of the text (the nucleus). Then the second sub-model ranks the significant parts in the primary rhetorical-summary based on the cosine similarity feature. To evaluate the proposed model, a prototype was developed on a range of articles, which have been classified into three groups different in size. The final output summary was evaluated in relation to its manual counterpart. In terms of enhancement of the rhetorical-summary precision, the experiment shows that proposed model HSM average precision is 71.6%, superior over the primary rhetorical-summary precision 56.3%.
本文运用修辞结构理论(RST)的语义学方法,根据功能和语义标准,找出最重要的段落。然而,当处理大型文档时,RST摘要的质量会受到影响。本文提出了一种新的阿拉伯语文本混合摘要模型,该模型混合了两个子模型:第一个子模型利用修辞结构理论生成初级摘要,以识别文本中一系列最重要的部分(核心)。第二个子模型基于余弦相似性特征对初级修辞摘要中的重要部分进行排序。为了评估所提出的模型,在一系列物品上开发了一个原型,这些物品被分为大小不同的三组。最后的输出摘要是根据其手动副本进行评估的。在提高修辞学摘要精度方面,实验表明,该模型的平均精度为71.6%,优于初级修辞学摘要精度56.3%。

Statistical methods to correlate multiple variables has long been applied in many fields of research. This paper applies such techniques to Unified Parkinson's Disease Rating Scale (UPDRS) data to examine relationships between speech and movement variables. This data analysis uses select speech and motor variables to explore Parkinson's Disease (PD) symptom correlations. The analysis is a prerequisite study of speech and movement symptoms prior to collecting data from everyday living in PD patients using HCI systems for movement and AI methods for analyzing speech and language. This data analysis is a first level examination of the current gold standards for measuring speech and movement in PD patients.

A compactified horizontal visibility graph for the language network and identification of the words that define the informational structure of a text is proposed. It was found that the networks constructed in such a way are scale free, and have a property that among the nodes with largest degrees there are words that determine not only communicative text structure, but also its informational structure.

This paper deals with a computer-aided system for design of ship power plants safe for their operators. The specificity of ship power plants allows to assert that all plant spaces can be more or less dangerous for operators carrying out any operational or maintenance tasks. For this reason, these plants should be well-designed to minimize the possible hazards for their operators. The proposed system of the hazard zone identification in the ship power plants is based on both their preliminary design and the expert subjective assessments enable to assess the potential risk for operators. It has been prepared a special questionnaire to collect this kind of subjective information. The acquired results have been used to build the risk assessment system with the fuzzy knowledge base.

A maximum sensibility neural network is implemented in an embedded system to make an online machine learning system, which is used to control the temperature of a small chamber. This is made by manually controlling the temperature to different set-points with a potentiometer, and using these values as an online training data for the neural network. Then the neural network is able to automatically adjust the temperature to any given set point with a good performance.

Fingerprint Verification Using the Center of Mass and Learning Vector Quantization 基于质心和学习向量量化的指纹验证
Pub Date : 2013-11-24 DOI: 10.1109/MICAI.2013.21
C. A. D. L. Ortega, Jorge A. Ramirez-Marquez, M. Mora-González, J. Romo, Cesar A. Lopez-Luevano
This paper describes a new implementation of a mixture of techniques not used before for fingerprint recognition. The implementation consists of three stages: the location of the core, which is done through Radon transformation, the extraction of features (out of which a square fingerprint is produced with the core, and the center of the mass is obtained from it), in stage three, the resulting image is used to train the neural network in order to obtain better LVQ classification. The improvement of effectiveness is tested using two databases of fingerprints. Correct recognition rates have exceeded 90 percent, which demonstrate its great stability with fingerprints that display a well-defined core.

A Hybrid Model Based on Neural Networks for Financial Time Series 基于神经网络的金融时间序列混合模型
Pub Date : 2013-11-24 DOI: 10.1109/MICAI.2013.17

Because of their fuzzy and non-stationary nature, financial time series forecasting is still a challenge. In this paper, we propose and implement a hybrid model by combining the Maximum Entropy (ME), Support Vector Regression (SVR) and Trend model based on Artificial neural networks (ANNs) for forecasting financial time series. The approach contains three steps: feature and time alignment in data preprocessing, adopting ME, SVR and Trend model for different features as the input for ANNs, and obtaining the final predicted value using Back Propagation algorithm. The feature selection flexibility of ME and global optimality of SVR make the input model better because of its different features, which helps to have a better forecasting accuracy of ANN sin proposed model. Experimental results clearly show that the accuracy of prediction for Chinese closed-end fund net value can achieve 98.3% using the hybrid model, which is more accurate than some institutions or known financial websites in China, and we provide the prediction of real time fund net value for free in our Hai tianyuan knowledge service platformhttp://www.haitianyuan.com.
由于金融时间序列的模糊性和非平稳性,其预测仍然是一个挑战。本文提出并实现了一种基于人工神经网络(ann)的最大熵(ME)、支持向量回归(SVR)和趋势模型相结合的金融时间序列预测混合模型。该方法包括三个步骤:在数据预处理中对特征和时间进行对齐,采用针对不同特征的ME、SVR和Trend模型作为人工神经网络的输入,使用反向传播算法获得最终预测值。神经网络的特征选择灵活性和支持向量回归的全局最优性使得输入模型的特征不同,使得神经网络模型具有更好的预测精度。实验结果清楚地表明,使用混合模型对中国封闭式基金净值的预测准确率可以达到98.3%,比国内一些机构或知名金融网站的预测准确率更高,我们在海天源知识服务平台(http://www.haitianyuan.com)上免费提供实时基金净值预测。

Automatic Quality Assessment of Documents with Application to Essay Grading 自动质量评估文件与应用论文评分
Pub Date : 2013-11-24 DOI: 10.1109/MICAI.2013.34

In this paper, we focus on automatic quality assessment for intelligent essay grading. Our devised system grades essays without depending upon completely overlapping essays in training data. This increases the scope of devised system due to list dependency on highly topic focused labeled data for automatic essay grading. Instead of depending upon direct topic specific matching w.r.t., training data, the devised system judge the quality of essay by exploiting knowledgebase documents and SentiWordNet, etc. To achieve this goal, we concentrate on five different features: (1) relevance of information, (2) presence of sparsely connected words, (3) statistical and semantic role of words, (4) presence of talkative terms and (5) length of essay. We extract all these features by using word graph of text, populated with statistical, semantic and topical relation between words. Next, we use graph theoretical techniques, like: weighted all pair shortest paths, Ego-Networks, entropy based measures for effectiveness of nodes in weighted graph and statistical and probabilistic techniques like: total correlation score and Point wise Mutual Information (PMI) etc. Our experimental result on standard dataset shows that our devised system performs better than state-of-the-Art systems of this area.
在本文中,我们关注的是智能作文评分的自动质量评估。我们设计的系统对文章进行评分,而不依赖于训练数据中完全重叠的文章。这增加了设计系统的范围,因为列表依赖于高度关注主题的标记数据,用于自动作文评分。设计的系统不是依赖于直接的主题特定匹配w.r.t、训练数据,而是利用知识库文档和SentiWordNet等来判断文章的质量。为了实现这一目标,我们专注于五个不同的特征:(1)信息的相关性,(2)稀疏连接词的存在,(3)词的统计和语义作用,(4)健谈术语的存在和(5)文章的长度。我们利用文本的词图提取所有这些特征,并填充词之间的统计关系、语义关系和主题关系。接下来,我们使用图理论技术,如:加权全对最短路径,自我网络,加权图中节点有效性的基于熵的度量,以及统计和概率技术,如:总相关分数和点明智互信息(PMI)等。我们在标准数据集上的实验结果表明,我们设计的系统比该领域最先进的系统性能更好。

This increases the scope of devised system due to list dependency on highly topic focused labeled data for automatic essay grading. Instead of depending upon direct topic specific matching w.r.t., training data, the devised system judge the quality of essay by exploiting knowledgebase documents and SentiWordNet, etc. To achieve this goal, we concentrate on five different features: (1) relevance of information, (2) presence of sparsely connected words, (3) statistical and semantic role of words, (4) presence of talkative terms and (5) length of essay. We extract all these features by using word graph of text, populated with statistical, semantic and topical relation between words. Next, we use graph theoretical techniques, like: weighted all pair shortest paths, Ego-Networks, entropy based measures for effectiveness of nodes in weighted graph and statistical and probabilistic techniques like: total correlation score and Point wise Mutual Information (PMI) etc. Our experimental result on standard dataset shows that our devised system performs better than state-of-the-Art systems of this area.","PeriodicalId":340039,"journal":{"name":"2013 12th Mexican International Conference on Artificial Intelligence","volume":"351 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122839110","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}
