Aperion — Cross-Hospital EEG for Parkinson's
An open-source Python package I built for honest, leakage-safe resting-state EEG analysis. It classifies Parkinson's disease vs. healthy controls from brain activity — and, crucially, keeps working on hospitals it has never seen. Aperion separates the aperiodic 1/f background from oscillatory peaks (FOOOF), harmonizes away site-specific effects, and is validated leave-one-dataset-out across three hospital cohorts — with built-in leakage and hospital-probe controls so the results stay trustworthy rather than over-claimed.
