马尔可夫链比较

Markov chain comparison

Martin Dyer, Leslie Ann Goldberg, Mark Jerrum, Russell Martin

摘要:

这是一篇简要的论文,重点是以下场景。我们有两个马尔可夫链,$\mathcal {M}$和$\mathcal {M}'$。通过某种方法,我们得到了$\mathcal {M}'$混合时间的一个界.我们希望比较$\mathcal {M}$与$\mathcal {M}'$,以便推导出$\mathcal {M}$的混合时间的相应界限。我们调查的比较方法的Diaconis和Saloff-Coste这种情况下的应用,给出了一些定理的特点的方法的适用性。我们特别关注的情况下,链是不可逆的。本文的目的是提供一个目录的定理,可以很容易地应用到绑定混合时间。

英文摘要:

This is an expository paper, focussing on the following scenario. We have two Markov chains, $\mathcal {M}$ and $\mathcal {M}'$. By some means, we have obtained a bound on the mixing time of $\mathcal {M}'$. We wish to compare $\mathcal {M}$ with $\mathcal {M}'$ in order to derive a corresponding bound on the mixing time of $\mathcal {M}$. We investigate the application of the comparison method of Diaconis and Saloff-Coste to this scenario, giving a number of theorems which characterize the applicability of the method. We focus particularly on the case in which the chains are not reversible. The purpose of the paper is to provide a catalogue of theorems which can be easily applied to bound mixing times.
