Proximal-IMH: Proximal Posterior Proposals for Independent Metropolis–Hastings with Approximate Operators
ICML 2026poster
Independent Metropolis–Hastings (IMH) algorithms are widely used in Bayesian inference, but their efficiency deteriorates when proposal distributions are constructed from inaccurate or approximate models. We introduce Proximal-IMH, an IMH method that enhances proposal distributions through a proxima…
