"WebApr 13, 2024 · Schizophrenia (SZ) is a serious mental disorder that could seriously affect the patient’s quality of life. In recent years, detection of SZ based on deep learning (DL) using electroencephalogram (EEG) has received increasing attention. In this paper, we proposed an end-to-end recurrent auto-encoder (RAE) model to detect SZ. " - Eeg sensitivity formula
