New EEG generation framework improves signal quality for BCIs

Researchers have developed a novel framework for generating electroencephalography (EEG) data, addressing the heterogeneity of EEG signals by introducing Position-Adaptive Time Scheduling. This method tracks per-position reconstruction error to adjust a position-specific time progress within the flow matching trajectory. The framework also incorporates Factorized Spatio-Temporal Attention and a frequency-aligned spectral consistency loss to improve signal quality and model inter-channel dependencies. Experiments on three EEG datasets demonstrated significant improvements, reducing TS-FID by up to 62.2% and enhancing downstream classification accuracy gain by up to 6.77 percentage points, making it a promising step for data augmentation in brain-computer interface applications.
