AI总结:

针对多峰分布尤其是高维场景下的采样难题,本文梳理了并行退火、模态跳跃、Wang-Landau等主流MCMC算法及近年前沿方法,并通过多类分布示例完成验证。

摘要:

本文阐述了从多峰分布中采样的核心挑战,尤其是高维场景下的相关难题。介绍了针对该问题设计的几类主要MCMC算法,包括parallel tempering(并行退火)、mode jumping(模态跳跃)和Wang-Landau算法,以及近年提出的多种前沿方法。并通过离散与连续状态空间下的合成及真实多峰分布示例,对这些方法进行了验证。

英文摘要:

We explain the fundamental challenges of sampling from multimodal distributions, particularly for high-dimensional problems. We present the major types of MCMC algorithms that are designed for this purpose, including parallel tempering, mode jumping and Wang-Landau, as well as several state-of-the-art approaches that have recently been proposed. We demonstrate these methods using both synthetic and real-world examples of multimodal distributions with discrete or continuous state spaces.
