Summary
This study introduces a novel hybrid model for classifying stress states using electroencephalography (EEG) signals, achieving over 92% accuracy. The system automates stress level detection, aiding mental health management.
Area of Science:
- Neuroscience
- Computational Biology
- Machine Learning
Background:
- Accurate stress detection from electroencephalography (EEG) signals is vital for mental health.
- Extracting emotional information from complex EEG patterns presents a significant challenge.
Purpose of the Study:
- To develop an automated hybrid model for classifying stress states using EEG signals.
- To improve early intervention and mental health management through reliable stress identification.
Main Methods:
- EEG signal purification using Independent Component Analysis (ICA).
- Multi-domain representation of EEG data via Fractional Fourier Transform (FrFT).
- Feature extraction using a two-layer 2D-PCANet and classification with Support Vector Machine (SVM).
Main Results:
- The proposed hybrid model achieved an average accuracy exceeding 92% on a self-collected EEG dataset.
- Successful stress state detection was demonstrated under various task-induced conditions.
- The model effectively distills stress-related features from complex EEG data.
Conclusions:
- The hybrid TrEn and 2D-PCANet model offers a robust and accurate method for automated stress classification from EEG.
- This approach holds promise for developing practical tools for mental health monitoring.
- Further research can explore broader applications and refine the model for diverse populations.
