MA-SBI: Misspecification-Aware Simulation-Based Inference via Side-Channel Guidance
Researchers propose MA-SBI, a misspecification-aware simulation-based inference framework that leverages unstructured side-channel information—such as regime labels or policy bulletins—to correct posterior estimates without requiring ground-truth parameter pairs. The method matches oracle performance on hide-the-calibration benchmarks and improves log-likelihood on real COVID epidemiological data.
Bayesian 3D Steerable CNNs Combine Equivariance and Uncertainty Quantification
A research paper proposes a Bayesian Steerable-CNN that simultaneously preserves SE(3)-equivariance and enables uncertainty quantification. The model achieves an expected calibration error of 0.0263 and outperforms its deterministic counterpart by up to 6.17% under distributional shift. The framework decomposes uncertainty into epistemic and aleatoric components, with a statistically significant negative correlation between epistemic uncertainty and prediction error.
