Abstract:Epilepsy is a chronic disease caused by sudden abnormal discharge of brain neurons, which leads to temporary brain dysfunction. The high-frequency oscillation of epileptic EEG signals is a reliable biomarker for epilepsy occurrence. In order to effectively diagnose and treat epilepsy, accurate detection of high-frequency oscillations in epileptic EEG is crucial. The automatic detection algorithm for high-frequency oscillations in epilepsy EEG first extracts relevant features from EEG signals, and then uses machine learning algorithms to identify and classify high-frequency oscillations. Firstly, introduce the definition and clinical research significance of high-frequency oscillations in epileptic EEG; then, summarize the feature extraction and classification of high-frequency oscillations in epileptic EEG; finally, the current research status and future research directions of automatic detection of high-frequency oscillations in epilepsy EEG are elaborated.

Keywords: epilepsy; EEG; high-frequency oscillations; feature extraction; feature classification
