| Abstract(in English) | This study aims to classify cognitive states by support vector machines (SVM) from EEG spectrum. Spontaneous brain waves were measured from a scalp of subjects with electrocap who opened their eyes, closed their eyes and performed a mental calculation task. Training data for SVMs consists of spectrum calculated from data selected by applying a sliding time window on the measured EEG. Classification accuracy for open/close states exceeds 90%, for close-eyes/mental calculation task was over 80%, suggesting that EEG spectrum can be used for accurate estimation of cognitive states by SVMs. |
