Consumer-friendly EEG-based Emotion Recognition System: A Multi-scale Convolutional Neural Network Approach
This work addresses emotion recognition for consumers using EEG, offering a novel method that improves performance in a real-life context, though it is incremental in advancing existing deep learning approaches.
The authors tackled EEG-based emotion recognition by proposing a multi-scale convolutional neural network that extracts features using kernels with various ratio coefficients and a novel kernel learning from four brain areas, achieving consistent outperformance over the state-of-the-art TSception model in predicting valence, arousal, and dominance scores across multiple metrics.
EEG is a non-invasive, safe, and low-risk method to record electrophysiological signals inside the brain. Especially with recent technology developments like dry electrodes, consumer-grade EEG devices, and rapid advances in machine learning, EEG is commonly used as a resource for automatic emotion recognition. With the aim to develop a deep learning model that can perform EEG-based emotion recognition in a real-life context, we propose a novel approach to utilize multi-scale convolutional neural networks to accomplish such tasks. By implementing feature extraction kernels with many ratio coefficients as well as a new type of kernel that learns key information from four separate areas of the brain, our model consistently outperforms the state-of-the-art TSception model in predicting valence, arousal, and dominance scores across many performance evaluation metrics.
