Abstract

Epileptic seizure detection is one of the important steps in diagnosis of epilepsy. Excellent automatic detection algorithm of epilepsy will help healthcare workers to better treat epilepsy patients, which has important study significance. In this paper, we proposed a new epileptic seizure detection method based on time domain features and weighted complex network of electroencephalogram (EEG) signals. Firstly, each EEG segment is divided into four sub-segments and each sub-segment is divided into thirty-two clusters. A set of time domain features is extracted from each cluster. Then, each set of this features is used as a node of complex network. Features sets are converted into weighted horizontal visibility graph. Thirdly, average weighted degree of complex network is extracted as the classification feature. Finally, average weighted degree is inputted into a linear classifier to classify epileptic EEG signals. The experimental result shows that the classification accuracy is up to 96.5%. The obtained result indicates that the proposed method is effective in epileptic seizure detection.
