WebJan 31, 2024 · Stein thinning is a promising algorithm proposed by (Riabiz et al., 2024) for post-processing outputs of Markov chain Monte Carlo (MCMC). The main principle is to greedily minimize the kernelized Stein discrepancy (KSD), which only requires the gradient of the log-target distribution, and is thus well-suited for Bayesian inference.The main … WebNov 23, 2024 · 23 Nov 2024, 07:42 (modified: 10 Jan 2024, 17:10) AABI2024 Readers: Everyone Abstract: The use of heuristics to assess the convergence and compress the output of Markov chain Monte Carlo can be sub-optimal in terms of the empirical approximations that are produced.

WebThese include discrepancy minimisation, gradient flows and control functionals—all of which have the potential to deliver faster convergence than a Monte Carlo method. In this talk we will see how ideas from discrepancy minimisation can be applied to the problem of optimal thinning of MCMC output.
