EEG classification algorithm for epilepsy based on time-delayed embedded hidden Markov model
Electroencephalogram(EEG)classification for epilepsy can offer powerful technical assistance for both its early warning and progression monitoring.However,traditional recognition methods for epilepsy EEG need to extract features from long-term time series,which cannot characterize the transient changes of brain and result in lower efficiency for epilepsy recognition and higher time consumption.These shortages further restrict the effectiveness of early warning for epilepsy.To address these problems,we proposed a novel epilepsy classification method based on hidden Markov model(HMM),which adopted the time-delay embedded HMM(TDE-HMM)to extract features of state transformation from estimated state series and utilized multiple layer perceptron(MLP)to further identify different seizure stages.The experimental results proved that compared with discrete wavelet transformation,power spectral density and differential entropy,our proposed method holds higher classification and capability of characterizing the state transformations of different seizure stages,which offers a novel alternative for the epilepsy classification and state analysis.
