Self-Supervised Learning for Anomalous Channel Detection in EEG Graphs: Application to Seizure Analysis

AAAI 2023technical

Electroencephalogram (EEG) signals are effective tools towards seizure analysis where one of the most important challenges is accurate detection of seizure events and brain regions in which seizure happens or initiates. However, all existing machine learning-based algorithms for seizure analysis req…
