METHOD FOR DETECTING EPILEPTIFORM DISCHARGES IN LONG-TERM EEG RECORDING Russian patent published in 2021 - IPC G06N20/00 A61B5/31 

FIELD: computing technology.

SUBSTANCE: invention relates to medicine and computing technology. The method comprises the stages wherein at least one EEG signal is preprocessed on a computing device, where local extrema with a window of 0.02 seconds are identified in at least one EEG signal, wherein each extremum is marked in accordance with the available markup; indicators are calculated for each extremum based on the original EEG signal and the wavelet transformation of the original EEG signal; a sample of indicators and marked marks is received by the input of the classifier designed for assessment of the probability of presence of epileptiform patterns in a signal segment; to reduce the number of false negatives, the probability threshold is determined as equal to 5%; post-processing of the obtained results of the classifier is conducted, close extrema marked as epileptiform are combined into one epileptiform discharge.

EFFECT: ensured accurate detection of generalised epileptiform discharges, reduced number of skipped discharges and reduced time for detection of generalised epileptiform discharges.
