EEG foundation models fall into 'Identity Trap,' study finds

Researchers have identified a significant issue in EEG foundation models, termed the "Identity Trap," where models achieve high accuracy by learning subject-specific features rather than genuine clinical biomarkers. A new diagnostic tool, FMScope, was developed to identify this shortcut learning at the representation level. The tool's application revealed that subject-variance is a dominant factor in model performance, and erasing these identity features can improve the decoding of actual clinical markers. AI
