Abstrakt
Rejestracja sygnałów elektroencefalograficznych (EEG) jest niemal zawsze związana z zapisem różnego rodzaju artefaktów, które zaszumianą odczyt i utrudniają analizę zebranych danych. Artefakty te mogą być zauważalne w pojedynczych kanałach, ale bardzo często muszą być korygowane na przestrzeni kilku kanałów jednocześnie. Ich pochodzenie może być różnorodne. Wyróżnia się artefakty sieciowe, sprzętowe jak również kilka rodzajów artefaktów mięśniowych, pochodzących od badanej osoby. W ostatnich latach obserwuje się wzrost zainteresowania badaniami EEG nie tylko w zastosowaniach ambulatoryjnych i klinicznych, ale także w analizach psychologicznych oraz w budowie nowoczesnych interfejsów człowiek-maszyna. Artykuł przedstawia studium przypadku zastosowania analiz klasyfikacyjnych w zagadnieniach korekcji artefaktów sygnału EEG.
