摘要: Brain-computer interfaces (BCIs) are systems that record brain signals and then classify them to generate computer commands. Keeping a minimal number of channels (electrodes) is essential for developing portable BCIs. Unlike existing methods choosing without optimization time segment classification, this work proposes novel subject-specific channel selection method based on criterion derived from Fisher's discriminant analysis realize the parametrization both positions. The experimental results show can efficiently reduce (from 118 no more than 11), shorten training time, significant decrease classification accuracy standard dataset.
