A new research paper published on arXiv evaluates five publicly available EEG foundation models and an in-house model, introducing a controlled protocol to assess their performance. The study found that the controls significantly impact model readings, with layer selection based on test scores improving performance and random initialization matching or surpassing pre-training in some cases. Furthermore, after full fine-tuning, only a small fraction of model pairs showed gains beyond their seed spread, and a baseline model using spectral features often performed comparably or better on specific tasks.
