New preprint frames Bayesian experimental design under misspecification as a max-min game

canaesseth · x · 2026-11-10

A new preprint, to be presented at NeurIPS 2026 in Paris this December, studies Bayesian experimental design under model misspecification. The authors frame it as a max-min game and derive a robust expected information gain measure based on Sibson's alpha-mutual information. A follow-up preprint is teased, proposing a risk-sensitive RL approach to amortizing robust sequential experimental design.
