Given a convex function $ f $ on $\mathbb {R}^ n $ with an integer minimizer, we show how
to find an exact minimizer of $ f $ using $ O (n^ 2\log n) $ calls to a separation oracle and …

A strongly polynomial algorithm for approximate forster transforms and its application to halfspace learning

I Diakonikolas, C Tzamos, DM Kane - Proceedings of the 55th Annual …, 2023 - dl.acm.org
The Forster transform is a method of regularizing a dataset by placing it in radial isotropic
position while maintaining some of its essential properties. Forster transforms have played a …
