TL;DR
本文介绍了使用随机零阶查询优化高维凸函数的问题,提出了两种算法,并表明两种算法只依赖于问题的环境维度的对数收敛率。实证研究证明了理论发现,并表明我们设计的算法在高维场景中优于经典的零阶优化方法。
Abstract
We consider the problem of optimizing a
high-dimensional
convex function
using stochastic zeroth-order query oracles. Such problems arise naturally in a variety of practical applications, including optimizing exp
