(A) Non-seizure data were obtained from 5 min of electroencephalogram (EEG) before and after each seizure. (B) Half overlapping 5-sec sliding windows were used to collect non-seizure data. (C) Five-sec segments per 0.25 sec were collected for seizure data to multiply the scarce seizure data. (D) While autodetecting seizure events, the entire EEG was scanned with half overlapping 5-sec sliding windows.
