Differing from the classical approaches, in which generating fixations is based on explicit search, we introduce the requirement that the search strategy must be accompanied by a series of saccades whose nature control the fixation process. In the explicit search approach, first, the scene point whose color is most similar to the “looked-for” color is determined and then the camera is made to move to that point. In the artificial potential functions approach, the two stages are merged together where the camera simply starts moving towards a point whose color is similar to the target color - although not necessarily the most similar. We present working implementations of the two approaches - reporting actual experiments with an attentive robot and comparing the resulting search behaviors.","PeriodicalId":219938,"journal":{"name":"2009 IEEE 17th Signal Processing and Communications Applications Conference","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131715182","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}

Especially when the number of labeled examples is small due to expense or difficulty of obtaining labels, Co-training can improve classifier performance. In this paper, Co-MRMR algorithm which uses classifiers trained on different feature subsets for Co-training is used for audio music genre classification. The features are selected with MRMR (minimum redundancy maximum relevance)feature selection algorithm. Two different feature sets, obtained from Marsyas and Music Miner software are evaluated for Co-training. Experimental results show that Co-MRMR gives better results than the random subspace method for Co-training (RASCO) which was suggested by Wang et al. in 2008 and traditional Co-training algorithm.","PeriodicalId":219938,"journal":{"name":"2009 IEEE 17th Signal Processing and Communications Applications Conference","volume":"57 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116425354","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 the other hand, sending simple channel log likelihood ratio (CLLR) in the cases that relaying users are unable to decode their partner's data, improves the bit error probability (BEP) performance of the system by achieving cooperative diversity gain, when the channel between two cooperating users is reliable. However, in adverse inter-user channel, exploiting channel reliability information is not appropriate. Simulation results show that the CLLR-based IRCC method has superior performance compared to that of the conventional IRCC method at high SNR and has inferior performance compared to that of conventional one at low SNR. Therefore, by combining two methods, we can achieve better performance in low as well as high SNR.","PeriodicalId":219938,"journal":{"name":"2009 IEEE 17th Signal Processing and Communications Applications Conference","volume":"109 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115815796","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}
