A study published on arXiv explored the effectiveness of different adapter designs for electroencephalography (EEG) foundation models. Researchers compared a "backbone-informed" adapter, which models relationships across channels and time, against a simpler token-wise multilayer perceptron. When trainable parameter counts were matched and the pretrained encoder was kept fixed, the backbone-informed adapter showed no consistent advantage across tasks like emotion recognition, sleep staging, and EEG event classification. In some cases, the token-wise control even performed better, suggesting that the relative performance of these adapters is dependent on the specific backbone, task, and downstream training protocol. AI
IMPACT Suggests that specialized adapter designs may not always outperform simpler, capacity-matched alternatives for EEG foundation models.
