Adjusting Regression Models for Conditional Uncertainty Calibration

Summary: | Conformal Prediction methods have finite-sample distribution-free marginal
coverage guarantees. However, they generally do not offer conditional coverage
guarantees, which can be important for high-stakes decisions. In this paper, we
propose a novel algorithm to train a regression function to improve the
conditional coverage after applying the split conformal prediction procedure.
We establish an upper bound for the miscoverage gap between the conditional
coverage and the nominal coverage rate and propose an end-to-end algorithm to
control this upper bound. We demonstrate the efficacy of our method empirically
on synthetic and real-world datasets. |
