Optimal thinning of mcmc output

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. WebIn this paper we propose a novel method, called Stein Thinning, that selects an indexset π, of specified cardinality m, such that the associated empirical approximation is closeto optimal. The method is designed to ensure that (2) is a consistent approximation of P .
