摘要: Fast classification of sleep and wake stages using a single EEG channel is proposed.The dataset was provided by Physionet.Speed accuracy PLS were compared with those k-NN, Bayes LDC classifiers.Results indicated that the Pz-Cz had better than Fpz-Cz channel.We achieved 91% selecting as classifier. Since speed important to real-time applications, this study proposed fast electroencephalograph (EEG) channel. Changes in are accompanied changes frequency spectrum signals; so, features extracted from 5-s epoch auto-regressive (AR) coefficients used represent signals different stages. The method based on partial least squares regression (PLS), which classify these finding an optimum beta K-fold cross validation. Physionet database confirm system. This system could be implementations because its high rate, capability implemented hardware owing very comfortable. Finally, results other classifiers such k-nearest neighborhood (k-NN), linear discriminant classifier (LDC) Bayes. We These comparisons revealed algorithm recognize emergency situation less 1s accuracy.
