AI 中文摘要
从von Mises-Fisher分布进行随机模拟的标准方法是Ulrich和Wood提出的拒绝采样器。本文为其效率提供了理论证明，在维度和浓度参数上均匀地给出了其接受概率的下界。本文还对该提议给出了一种新颖的解释，为这种效率提供了一些直观理解。
英文摘要
The standard approach to stochastic simulation from the von Mises-Fisher distribution is a rejection sampler proposed by Ulrich and Wood. This note provides a theoretical justification of its efficiency, lower-bounding its acceptance probability uniformly over the dimension and concentration parameter. A novel interpretation of the proposal is given which provides some intuition for this efficiency.
