Despite the rapid advances of neuroimaging techniques, EEG recording con- tinues playing an important role in both the diagnosis of neurological diseases and understanding of the psychological process. In order to extract relevant information of brain electrical activity, a variety of computerized-analysis me- thods have been used. In this paper, we propose the use of a recently developed machine-leaning technique - relevance vector machine (RVM) - for EEG signals classification. RVM is based on Bayesian estimation theory, which has as distinctive feature the fact that it can yield a sparse decision function defined only by a very small number of so-called re- levance vectors. From the experimental results, we can see that estimation and classification based on RVM perform well in EEG signals classification problem compared with traditional approach support vector machine (SVM), which indicates that this classification method is valid and has promising application.","PeriodicalId":340055,"journal":{"name":"Anais do XXVI Simpósio Brasileiro de Telecomunicações","volume":"90 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132484397","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 novel method divides the compressed data into short blocks, what allows for near real time operation. The error protection is obtained through the application of BCH codes and block interleavers. Compared to other methods found in the literature, the proposed scheme is either more efficiency in terms of compression ratio or in terms of decoding delay.","PeriodicalId":340055,"journal":{"name":"Anais do XXVI Simpósio Brasileiro de Telecomunicações","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127774265","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}
