Improved T-Weight method in classification of slow cortical potentials

Published: 26 October 2011 Publication History

Abstract

In this paper, T-Weight Method is improved by integration of a threshold determination step into the original algorithm. The new method is called Improved T-Weight (ITW) Method and the performance of the ITW Method is evaluated on classification of slow cortical potentials (SCPs) for a brain-computer interface (BCI) task. Two different datasets from BCI Competition 2003 are used for classification. It is showed that ITW Method outperforms all the other submissions in the Competition in terms of classification error. Proposed method has a great potential to become a widely used classifier.
