From Gauss to Kolmogorov: Localized Measures of Complexity for Ellipses
Yuting Wei, Billy Fang, Martin J. Wainwright
The Gaussian width is a fundamental quantity in probability, statistics and geometry, known to underlie the intrinsic difficulty of estimation and hypothesis testing. In this work,…

The local geometry of testing in ellipses: Tight control via localized Kolmogorov widths
Yuting Wei, Martin J. Wainwright
We study the local geometry of testing a mean vector within a high-dimensional ellipse against a compound alternative. Given samples of a Gaussian random vector, the goal is to dis…
