Abstract
An automate classification of EEG time segments is frequently used technique across many neuro-scientific fields. Generally, segment classification results in labeled EEG time segments (e.g. physiological brain activity, epileptic activity, muscle artifacts or electrode artifacts). However, currently used methods are usually tested on artificial surrogate data and more general validation approach is needed. Here, a generalized statistical model of commonly used discriminating features obtained from real EEG data is presented for the first time. Multivariate probability density functions (PDFs) of classes are fitted on more than twenty thousand of testing segments from human EEG. An unique testing set is designed using a recent non-linear dimension reduction technique. Parametric and non-parametric PDF estimators are applied and compared in sense of feature space model.
