Abstract
We propose a combination of blind source separation (BSS) and independent component
analysis (ICA) (signal decomposition into artifacts and nonartifacts) with support vector machines (SVMs)
(automatic classification)
that are designed for online usage. In order to select a suitable BSS/ICA method, three ICA algorithms
(JADE, Infomax, and FastICA) and one BSS algorithm (AMUSE) are evaluated to determine their ability to
isolate electromyographic (EMG) and electrooculographic (EOG) artifacts into individual components. An
implementation of the selected BSS/ICA method with SVMs trained to classify EMG and EOG artifacts, which
enables the usage of the method as a filter in measurements with online feedback, is described. This filter is
evaluated on three BCI datasets as a proof-of-concept of the method.
