New research advances conformal prediction with volume optimization and covariate shift handling

By PulseAugur Editorial · [2 sources] ·

Two new research papers on arXiv introduce advanced conformal prediction techniques. The first paper, "Minimum Volume Optimal Transport for Multivariate Conformal Prediction," proposes a framework that learns a Mahalanobis ground cost to minimize prediction-region volume, offering substantial reductions in volume and improved coverage guarantees. The second paper, "Backward Conformal Prediction under Covariate Shift," extends backward conformal prediction to handle covariate shift using importance weighting and proposes estimating density ratios on sorted score vectors for more accurate miscoverage estimates.
