Classification of artifactual ICA components AbstractThe analysis of EEG signals for the use in BCI systems and for mental state monitoring applications is often impeded by artifacts caused by muscular activity or external technical sources. A promising approach for the reduction or removal of artifacts is based on methods of Blind Source Separation (BSS), which transform the original EEG signal into independent source components. In order to avoid the time-consuming hand rating of sources into artifactual and non-artifactual components, an automated method for their classification is proposed. Applying state of the art machine learning algorithms and nonlinear classification with a Support Vector Machine (SVM), the automated method shows a high level of agreement (90.5%) on unseen data with ratings of human experts.
