Constrained and Composite Optimization via Adaptive Sampling Methods

no code implementations31 Dec 2020 Yuchen Xie, Raghu Bollapragada, Richard Byrd, Jorge Nocedal

The motivation for this paper stems from the desire to develop an adaptive sampling method for solving constrained optimization problems in which the objective function is stochastic and the constraints are deterministic.

A Noise-Tolerant Quasi-Newton Algorithm for Unconstrained Optimization

Adaptive Sampling Strategies for Stochastic Optimization

no code implementations30 Oct 2017 Raghu Bollapragada, Richard Byrd, Jorge Nocedal

In this paper, we propose a stochastic optimization method that adaptively controls the sample size used in the computation of gradient approximations.
