Abstract

Student stress has emerged as a significant concern, requiring prompt identification to avoid serious repercussions. Unlike conventional EEG stress detection approaches that rely on feature extraction, our work introduces a novel combination of SNR-based augmentation with ShallowConvNet recognised for its simplicity and efficiency. Utilising the StressDB-UIA1 dataset, EEG data from 31 subjects were examined under stress and non-stress situations. The research tackles the issue of restricted EEG data availability by utilising Signal-to-Noise Ratio (SNR) based augmentation, replicating noise levels of 10 dB, 15 dB, and 20 dB. This augmentation strategy improves model robustness and generalisability to real-world situations. The results shows that ShallowConvNet, when trained on SNR-augmented datasets, attains enhanced accuracy and Area Under Curve (AUC) metrics, with peak performance recorded at 20 dB SNR (83.69% accuracy, 0.921 AUC). SNR-based augmentation is apparent in enhancing EEG classification and emphasise ShallowConvNet's capability for real-time stress monitoring, facilitating prompt interventions and mental health support systems.
