Bayesian Cramér-Rao Bound Estimation With Score-Based Models
ICASSP 2023accepted
The Bayesian Cramér-Rao bound (CRB) provides a lower bound on the mean square error of any estimator in Bayesian inference under mild regularity conditions. It benchmarks the performance of statistical estimation and can also serve as a principled metric for system design and optimization. However,…
