New method improves multi-dimensional forecast calibration

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a new method for online calibration of multi-dimensional forecasts over arbitrary convex sets. This approach connects calibration to external regret minimization in online linear optimization. The algorithm, which is identical across various settings, utilizes a swap regret minimization technique with the TreeSwap algorithm and Follow-The-Leader subroutine. AI

    High-Dimensional Calibration from Swap Regret

    arXiv:2505.21460v2 Announce Type: replace-cross Abstract: We study online calibration of multi-dimensional forecasts over an arbitrary convex set $P \subset \mathbb{R}^d$ relative to an arbitrary norm $|\cdot|$. We connect this to external regret minimization for online linear op…
