On additive averaging kernels for finite Markov chains

Ryan J. Y. Lim, Michael C. H. Choi

We study additive mixtures of Markov kernels of the form $A_{α} = α P + (1 - α) G$ , where $α \in [0, 1]$ , $P$ is a baseline sampler and $G$ is a Gibbs kernel induced by a partition of the s…

Optimising two-block averaging kernels to speed up Markov chains

Ryan J. Y. Lim, Michael C. H. Choi

We study the problem of selecting optimal two-block partitions to accelerate the mixing of finite Markov chains under group-averaging transformations. The main objectives considere…
