A contour extraction method is presented for the purpose of discrimination. A half contouring is devised for reducing the influence of shadow effect resulting from the ultrasonic energy decay. Based on the cue of contour variation, degree standard variation and texture information are developed as useful features for the discrimination. Above 70% accuracy could be obtained by using the adopted half contour information. Experiments confirm the feasibility of the proposed method.","PeriodicalId":335296,"journal":{"name":"2014 International Conference on Machine Learning and Cybernetics","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133657401","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 this paper, a unified framework is proposed to incorporate the supervised correlation exploration with the predictive model. In the framework, feature mappings to a low-dimensional subspace is obtained through a linear transformation guided by the label information. And a multi-label classifier is simultaneously built on the projected features. The framework leads to a trace optimization problem which can be solved by a generalized eigenvalue problem. Meanwhile, the dual form of the framework is presented to deal with different problems. Experiments on four datasets show that the proposed framework can achieve comparable performance with four other well-known methods, and achieve better performance when label correlations are important. It's also demonstrated that the framework is efficient when the dimensionality is low, and the dual form will be more efficient without extra computational tricks in the small-sample problems.","PeriodicalId":335296,"journal":{"name":"2014 International Conference on Machine Learning and Cybernetics","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128077510","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}

Therefore, the reverberation is highly corrected with the original speech signal. This leads to dramatically degrade the performance of speech recognition. This paper extends VTS methodology to develop a robust technique for HMM-driven beamformer on the reverberation environments. We approximate the logarithm of Gaussian mixture models of HMM with VTS expansion. This makes it possible to obtain a simpler updating functions of beamformer parameters than the counterparts of original HMM-driven beamformer. The RWCP database is used for the simulation of the multi-channel recorded reverberation speech. A speaker-independent speech query task of Mandarin names was applied to evaluate the performance of the beamformers. Our experimental results show that the proposed algorithm was effective on compoutation reduction for the adaptation process of HMM-driven beamformer. It indicates that the proposed framework benefits the development in robust speech recognition on resource-constrained platforms.","PeriodicalId":335296,"journal":{"name":"2014 International Conference on Machine Learning and Cybernetics","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128473771","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}

The proposed scheme is based on DCT coefficients and Radon transform. It combines the local feature with the global feature to detect suspicious images. The local feature vector is extracted by dividing blocks and selecting the largest DC coefficients. If the similarity is less than a threshold, the global feature vector will be extracted. Radon transform (RT) and discrete Fourier transform (DFT) are then exploited to extract the global feature vector. Experimental results demonstrate that the proposed scheme outperforms other existing techniques for image authentication.","PeriodicalId":335296,"journal":{"name":"2014 International Conference on Machine Learning and Cybernetics","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131669995","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}

Commonly used NMF algorithms mainly target on minimizing the l2 distance or the Kullback-Leibler (KL) divergence, which may not be suitable for nonlinear cases. In this paper, we propose a new decomposition method by maximizing the correntropy between the original and the product of two low-rank matrices for document clustering. This method also allows us to learn new basis vectors of the semantic feature space from data. To our knowledge, there is no existing work which clusters high dimensional document data by maximizing the correntropy in NMF.
