Distributed Computing And Electrical Circuits And Electronics

Medical experts employ electroencephalography (EEG) for analyzing the electrical activity in the brain to infer disorders. However, the time costs of human experts are very high, and the examination of EEGs by such experts, therefore, accounts for a plethora of medical resources. In this study, an improved one-dimensional CNN-only system of 25 layers has been proposed to identify abnormal and normal adult EEG signals using a single EEG montage without using any explicit feature extraction technique. Most of the previous systems based on deep learning, that have been proposed to solve this problem, use extremely deep architectures containing very large numbers of layers. This study also presents an independent preprocessing module that has been exhaustively evaluated for optimal parameters with the target of adult EEG signal classification. The achieved accuracy of the proposed classifier as a part of the decision support system is 82.24%, which is a substantial improvement of ~3% over the previous best-reported classifier of comparable depth. The system also exhibits significantly higher F1-score and sensitivity as well as lower loss. The proposed system is intended to be a part of an expert system for overall brain health evaluation.
