New calibration measure offers truthful predictions in machine learning
Researchers have introduced a new calibration measure called averaged two-bin calibration error (ATB) designed to be perfectly truthful. This measure quantifies how far a predictor is from perfect calibration and is min…

New research establishes optimal lower bounds for online multicalibration
Two new papers published on arXiv explore the theoretical underpinnings of multicalibration in machine learning. The first paper establishes tight lower bounds for online multicalibration, demonstrating an information-t…
