Multi-channel electroencephalogram(EEG)power spectrum is extracted for training continuous hidden Markov model(CHMM)
and a novel approach to classify the mental fatigue levels is proposed based on power spectrum-CHMM. The result shows that EEG power spectrum and the ratio of different rhythm serve as sensitive indices for mental fatigue
CHMM is effective for classifying metal fatigue levels with the highest classification accuracy of 97.5%.CHMM enables to classify more accurately comparing with back propagation neural network for the same training samples.
