The Brain-Computer Interface P300 speller aims at helping patients unable to activate muscle to spell words by means of their brain signal activities. Associated to this BCI paradigm, there is the problem of classifying electroencephalogram signals related to the mental spelling action. This paper addresses the problem of signal responses variability within a single subject in such Brain-Computer Interface. We propose a method that copes with such variabilities through an ensemble of classifier approach. Each classifier is composed of a linear Support Vector Machines trained on only a small part of the available data and for which a channel selection procedure has been performed. Performances of our algorithm has been evaluated on dataset II of the BCI Competition III and has yielded the maximum classification performance rate.
