Probing Spatial and Spectral Grounding in EEG Foundation Models
Kleanthis Avramidis · Ivan Tashev · Dimitra Emmanouilidou
Tests whether EEG foundation models actually rely on physiological channel and frequency structure, separating predictive performance from neural grounding.
BrainCodes: A Lightweight EEG Foundation Model over Discrete Neural Codes
Kleanthis Avramidis · Ivan Tashev · Dimitra Emmanouilidou
Learns discrete neural codes from more than 800 hours of EEG while using up to 97% fewer trainable parameters, suggesting compact principles for transferable AI.
