EEG foundation models benefit from pretrained time-series feature extractors

A new research paper explores the effectiveness of different temporal feature extractors within EEG foundation models. The study compares a linear baseline, a convolutional encoder, and a pretrained time-series foundation model (TSFM) called MOMENT. Results indicate that while simpler temporal representations are competitive for motor imagery tasks, richer temporal modeling is beneficial for emotion recognition. The research suggests that general-purpose time-series representations from pretrained TSFMs can be effectively transferred as frozen feature extractors for EEG foundation models. AI

IMPACT Suggests that general-purpose time-series representations can be effectively transferred to EEG foundation models, potentially improving performance on specific tasks.
