We used Genetic Algorithm(GA) to select some suitable features calculated ECG for sleep staging. Combine DHMM which is trained by using the codebook for all testing features. The trained DHMM model is used for sleep staging. Through the
evolution of GA and DHMM, better chromosomes or more suitable
features are obtained.
