| Abstract(in English) | The posterior probability in classification is useful information, which can be used for the rejection of uncertain classification results, for example. Reliability-based automatic repeat request (RB-ARQ), proposed by the authors to improve the performance of the brain-computer interface, also utilizes it. This paper compares three types of classifiers: LDA, SVM, and relevance vector machine (RVM), in terms of the estimation accuracy of the posterior probability and the classification performance when the rejection and RB-ARQ are applied. The results show that LDA is the best for the P300 speller with RB-ARQ, and RVM is the best for a motor imagery task with the rejection. |
