Conformal Prediction Robustness in EEG Seizure Classification
Research focusing on conformal prediction techniques for classifying EEG seizures indicates that shifts in patient distribution breach i.i.d. assumptions, leading to inadequate coverage in medical environments. By employing personalized calibration approaches, coverage can be enhanced by more than 20 percentage points without significantly altering the sizes of prediction sets. This implementation can be accessed through PyHealth, a publicly available AI framework for healthcare.
