New results on optimal deterministic multicalibration and omniprediction

arXiv·low signal

Noarov and Roth present optimal deterministic algorithms for multicalibration and omniprediction, ensuring predictions remain unbiased even conditioned on the prediction and across many overlapping group weightings. The theory underpins fairness and reliability guarantees that increasingly feed into responsible-AI requirements for deployed models. It is primarily of interest to researchers and teams building calibration guarantees into agent prediction layers.
