A new form of the nonlinearity implemented in the ICA approach is presented in the paper. The proposed independent component analysis based on differential entropy can be used for elimination of physiological artifacts from electroencephalographic signals. For verification of the quality of separation of the EEG data, the PI index is proposed. The second measure of accuracy is the normalized kurtosis...
W artykule przedstawiono analizę składowych niezależ- (ICA) jako narzędzie do separacji i usuwania niepożądanych komponentów z zapisu EEG. Do wykrywania i usuwania artefaktów (mruganie powiek, artefakty mięśniowe) z danych EEG wykorzystano następujące algorytmy: HJ, Cichockiego oraz Infomax.
