Minimizing Convex functions with Rational Minimizers
收藏 引用
JOURNAL OF THE ACM 2023年 第1期70卷 5-5页
作者: Jiang, Haotian Univ Washington 185 E Stevens Way NE Seattle WA 98195 USA
Given a separation oracle SO for a convex function f defined on R-n that has an integral minimizer inside a box with radius R, we show how to find an exact minimizer of f using at most O(n(n log log(n)/ log(n) + log(R... 详细信息

Joint continuous and discrete model selection via submodularity
The Journal of Machine Learning Research
收藏 引用
The Journal of Machine Learning Research 2022年 第1期23卷 14813-14854页
作者: Jonathan Bunton Paulo Tabuada Department of Electrical & Computer Engineering University of California Los Angeles Los Angeles CA
In model selection problems for machine learning, the desire for a well-performing model with meaningful structure is typically expressed through a regularized optimization problem. In many scenarios, however, the mea... 详细信息

Active-set methods for submodular minimization problems
The Journal of Machine Learning Research
收藏 引用
The Journal of Machine Learning Research 2017年 第1期18卷
作者: K. S. Sesh Kumar Francis Bach Imperial College London Department of Computing London INRIA Département d'Informatique de l'Ecole Normale Supérieure (UMR CNRS/ENS/INRIA) Paris France
We consider the submodular function minimization (SFM) and the quadratic minimization problems regularized by the Lovász extension of the submodular function. These optimization problems are intimately related; f... 详细信息
