摘要

最近在arXiv上发表的一篇论文提出了费舍尔宽度的概念，这是一种新颖的几何度量，旨在评估统计流形中的复杂性。该度量将传统的高斯宽度适应于黎曼几何框架，使其能够考虑局部统计曲率。费舍尔宽度的一个关键特征是其在平滑重新参数化下的不变性，这增强了其在各种统计背景下的适用性。

A recent paper published on arXiv presents the concept of Fisher width, a novel geometric measure designed to assess complexity within statistical manifolds. This new measure adapts the traditional Gaussian width to the framework of Riemannian geometry, allowing it to consider local statistical curvature. One of the key features of Fisher width is its invariance under smooth reparameterizations, which enhances its applicability in various statistical contexts.
