Calibrating Neural Simulation-Based Inference with Differentiable Coverage Probability

NeurIPS 2023poster

Bayesian inference allows expressing the uncertainty of posterior belief under a probabilistic model given prior information and the likelihood of the evidence. Predominantly, the likelihood function is only implicitly established by a simulator posing the need for simulation-based inference (SBI).…

Towards Reliable Simulation-Based Inference with Balanced Neural Ratio Estimation

NeurIPS 2022accept

Modern approaches for simulation-based inference build upon deep learning surrogates to enable approximate Bayesian inference with computer simulators. In practice, the estimated posteriors' computational faithfulness is, however, rarely guaranteed. For example, Hermans et al., 2021 have shown that…
