Classification of Electroencephalographic Signalsfor Brain-Computer Interface

Abstract: Brain-computer interface is a promising research area that has the potential to aid impaired individuals in their daily lives. There are several different methods for capturing brain signals, both invasive and noninvasive. A popular noninvasive technique is electroencephalography (EEG). It is of great interest to be able to interpret EEG signals accurately so that a machine can carry out correct instructions. This paper looks at different machine learning techniques, both linear and nonlinear, in an attempt to classify EEG signals. It is found that support vector machines provide more satisfactory results than neural networks.
