A Multi-dimensional Framework for Evaluating Generalization in EEG Foundation Models

arXiv:2605.28563v1 Announce Type: new Abstract: Evaluating foundation models under appropriate adaptation settings is essential for understanding the quality and transferability of the learned representations. Recent EEG foundation models have demonstrated promising transfer capabilities across tasks and datasets, motivating their growing use in neurotechnology and clinical applications. However, these models are typically evaluated under full fine-tuning on well-curated downstream datasets, a setting that does not reflect biomedical domain constraints such as limited labeled data, reduced sen

Why this matters
Why now

The proliferation of EEG foundation models necessitates robust evaluation frameworks to ensure their responsible and effective deployment in real-world neurotechnology and clinical settings.

Why it’s important

This framework addresses critical limitations in current EEG model evaluation, proposing methods that better reflect biomedical constraints, thus enabling more reliable and trustworthy AI applications in brain-computer interfaces and diagnostics.

What changes

The proposed multi-dimensional evaluation shifts the focus from simple fine-tuning to more comprehensive adaptation settings, directly influencing how future EEG foundation models are developed, validated, and adopted.
