Enhancing EEG Signal-Based Emotion Recognition With Synthetic Data: Diffusion Model Approach

This research paper describes a method to improve emotion recognition using EEG (electroencephalography, a technology that measures electrical activity in the brain) by generating synthetic EEG data through a diffusion model (a type of AI that creates new data by gradually removing noise from random data). The proposed approach achieved up to 5.6% better accuracy in identifying emotions compared to traditional methods, helping address the problem of not having enough real EEG data for training these systems.
