When the Model Should Say It Doesn't Know: Conformal Prediction Sets with MAPIE
How to add coverage-guaranteed prediction sets, temperature scaling calibration, and risk-coverage curves to a classifier using MAPIE — the pieces that make uncertainty quantification operationally useful rather than decorative.
Outcome: Added coverage-guaranteed prediction sets and operational abstention gates to a classification pipeline, cutting acted-upon error rate without retraining the model.
