It can be modeled as a pattern recognition problem and addressed by multi-class support vector machines (SVMs). In this paper, one-against-one SVM and directed a cyclic graph SVM are adopted to diagnose the faulty analog circuit. Aiming at the uncertainty of the node arrangement and the error accumulation phenomenon, the improved directed a cyclic graph SVM based on fisher separability measure in high dimensional feature space and margin of SVM is proposed. To further improve the diagnostic accuracy the combined kernel function based on Lévy kernel function and Gaussian kernel function is adopted. Experimental results show the effectiveness of the proposed method.","PeriodicalId":285687,"journal":{"name":"2013 International Conference on Information Technology and Applications","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127901150","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}

In the paper, the characteristics of traditional Chinese painting are analyzed firstly. Then, the process of constructing ontology for traditional Chinese painting is dissertated in details, including how to select appropriate classes and properties in CRM ontology and how to extend them in specific domain. In addition, the framework of retrieval is introduced. Ontology is a good avenue for knowledge sharing and information integration.

This paper deals with the problem of tracking multiple maneuvering targets using raw image observation. The multi-target state is formulated as random finite set and its posterior distribution is approximated by multi-Bernoulli parameters. Multiple model approach is proposed to accommodate the uncertainty of the possible target dynamics, and sequential Monte Carlo method is presented to implement the multiple-model multi-Bernoulli (MM-MeMBer) filter. The state estimates are obtained by combining the result of mode-dependent filtering for the Bernoulli components with high existence probabilities. Simulation results for multi-target track-before-detect application show the improved performance of the proposed method over MeMBer filters in the single-model fashion under the condition of equivalent computational complexity.","PeriodicalId":285687,"journal":{"name":"2013 International Conference on Information Technology and Applications","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134443813","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}

This method performs image quality assessment by incorporating a graphical model. To obtain the results of the image quality assessment, first, we use a set of pristine and distorted images without human subjective scores for training. Second, the images are represented by several quality-aware visual words that are based on natural scene statistic features. Third, author topic model is leveraged to estimate probability of topic for the regions in the test images. At last, the perceptual quality score of the whole image can be obtained by comparing the estimated probabilities of topics with the average distribution of topics for a large number of natural images. Experimental evaluation on the LIVE IQA database demonstrates that the proposed method correlates well with human difference mean opinion scores.","PeriodicalId":285687,"journal":{"name":"2013 International Conference on Information Technology and Applications","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125278829","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}
