UltraNest --一个健壮的通用贝叶斯推断引擎

UltraNest -- a robust, general purpose Bayesian inference engine

Johannes Buchner

摘要:

UltraNest是一个用于参数估计和模型比较的通用贝叶斯推断包。它允许拟合指定为用Python、C、C++、Fortran、Julia或R编写的似然函数的任意模型。UltraNest专注于正确性和速度(按此顺序),特别适用于多模态或非高斯参数空间,计算昂贵的模型,在强大的管道中。可对计算集群进行并行化并恢复未完成的运行。

英文摘要:

UltraNest is a general-purpose Bayesian inference package for parameter estimation and model comparison. It allows fitting arbitrary models specified as likelihood functions written in Python, C, C++, Fortran, Julia or R. With a focus on correctness and speed (in that order), UltraNest is especially useful for multi-modal or non-Gaussian parameter spaces, computational expensive models, in robust pipelines. Parallelisation to computing clusters and resuming incomplete runs is available.
