Maintaining Conformal Prediction Guarantees Amidst Data Shifts

Split conformal prediction offers coverage guarantees for model predictions, but these guarantees degrade when the underlying data distribution shifts over time. Practitioners face challenges in maintaining these guarantees in real-world applications where data can change unpredictably. Common strategies include periodic recalibration, monitoring empirical coverage to detect drops, or employing adaptive methods. Deciding how to handle prediction sets that contain multiple possible labels also remains a practical concern, with options ranging from human review to LLM-based routing. AI
