Accuracy and Performance Analysis of the 1/t wang-landau algorithm in the Joint Density of States Estimation
收藏 引用
OPTICAL MEMORY AND NEURAL NETWORKS 2024年 第3期33卷 302-307页
作者: Egorov, V. I. Kryzhanovsky, B. V. Russian Acad Sci Sci Res Inst Syst Anal Moscow 117312 Russia
The 1/t wang-landau algorithm is analyzed from the viewpoint of execution time and accuracy when it is used in computations of the density of states of a two-dimensional Ising model. We find that the simulation result... 详细信息

Efficiency of the wang-landau algorithm: A Simple Test Case
收藏 引用
APPLIED MATHEMATICS RESEARCH EXPRESS 2014年 第2期2014卷 275-311页
作者: Fort, Gersende Jourdain, Benjamin Kuhn, Estelle Lelievre, Tony Stoltz, Gabriel CNRS LTCI 46 Rue Barrault F-75634 Paris 13 France Telecom ParisTech F-75634 Paris 13 France Univ Paris Est CERMICS ENPC INRIA F-77455 Marne La Vallee France INRA Unite MIA F-78352 Jouy En Josas France
We analyze the efficiency of the wang-landau algorithm to sample a multimodal distribution on a prototypical simple test case. We show that the exit time from a metastable state is much smaller for the wang-landau dyn... 详细信息

Monte Carlo Approximation of Bayes Factors via Mixing With Surrogate Distributions
收藏 引用
JOURNAL OF THE AMERICAN STATISTICAL ASSOCIATION 2022年 第538期117卷 765-780页
作者: Dai, Chenguang Liu, Jun S. Harvard Univ Dept Stat Cambridge MA 02138 USA
By mixing the target posterior distribution with a surrogate distribution, of which the normalizing constant is tractable, we propose a method for estimating the marginal likelihood using the wang-landau algorithm. We... 详细信息
