我们介绍了熵估计和对数Sobolev不等式,以及准平稳分布的概念如何成为分析亚稳态过阻尼朗之万动力学的有用工具,特别是量化亚稳态的程度。我们讨论了这些方法在估计一些经典的加速采样算法的效率,以及评估一些粗粒度过程引入的误差方面的兴趣。本文是作者在2011年ENUMATH会议上的一次全体会议演讲的总结。
We present how entropy estimates and logarithmic Sobolev inequalities on the one hand, and the notion of quasi-stationary distribution on the other hand, are useful tools to analyze metastable overdamped Langevin dynamics, in particular to quantify the degree of metastability. We discuss the interest of these approaches to estimate the efficiency of some classical algorithms used to speed up the sampling, and to evaluate the error introduced by some coarse-graining procedures. This paper is a summary of a plenary talk given by the author at the ENUMATH 2011 conference.
