Group-averaged Markov chains II: tuning of group action in finite state space

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

We study group-averaged Markov chains obtained by augmenting a $π$ -stationary kernel $P$ with orbit kernels induced by a group action. We analyse the Gibbs ( $G$ ), Metropolis--Hasti…

Group-averaged Markov chains: mixing improvement

Michael C. H. Choi, Youjia Wang

For Markov kernels $P$ on a general state space $X$ , we introduce a new class of averaged Markov kernels $P_{d a} (G, ν)$ of $P$ induced by a group $G$ that acts on $\mathca…
