Decision Making under the Exponential Family: Distributionally Robust Optimisation with Bayesian Ambiguity Sets

ICML 2025spotlight

Decision making under uncertainty is challenging as the data-generating process (DGP) is often unknown. Bayesian inference proceeds by estimating the DGP through posterior beliefs on the model’s parameters. However, minimising the expected risk under these beliefs can lead to suboptimal decisions du…

Robust Bayesian Inference for Simulator-based Models via the MMD Posterior Bootstrap

AISTATS 2022poster

Simulator-based models are models for which the likelihood is intractable but simulation of synthetic data is possible. They are often used to describe complex real-world phenomena, and as such can often be misspecified in practice. Unfortunately, existing Bayesian approaches for simulators are know…
