New probes reveal how EEG foundation models process spatial and spectral data

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a new set of perturbation probes to better evaluate EEG foundation models. These probes assess how well the models understand the spatial and spectral characteristics of EEG signals, going beyond traditional downstream accuracy metrics. Experiments on five existing EEG foundation models revealed that some models encode electrode identity without relying on it for classification, while others can distinguish spectral details without specific responses to simulated clinical markers. This work highlights the importance of grounding probes in complementing performance-based evaluations for a deeper understanding of EEG foundation models. AI

IMPACT Provides a novel evaluation framework for EEG foundation models, potentially improving their interpretability and reliability in clinical settings.

    Probing Spatial and Spectral Grounding in EEG Foundation Models

    EEG foundation models are advancing at an unprecedented pace, yet their evaluation is driven by downstream accuracy, which reveals little about whether their predictions rely on physiologically interpretable signal structure. We introduce a set of perturbation probes in two groun…
