A Direction Adaptation Evaluation Strategy for Noisy Derivative-Free Optimization
Morteza Kimiaei, Mahsa Yousefi
In this paper, we develop a direction adaptation evolution strategy (DAES) -- a new MAES-type method -- for noisy derivative-free optimization, designed to reconcile the population…
A Projected Stochastic Gradient Method for Finite-Sum Problems with Linear Equality Constraints
Natasa Krklec Jerinkic, Benedetta Morini, Mahsa Yousefi
A stochastic gradient method for finite-sum minimization subject to deterministic linear constraints is proposed and analyzed. The procedure presented adapts the projected gradient…
Fully stochastic trust-region methods with Barzilai-Borwein steplengths
Stefania Bellavia, Benedetta Morini, Mahsa Yousefi
We investigate stochastic gradient methods and stochastic counterparts of the Barzilai-Borwein steplengths and their application to finite-sum minimization problems. Our proposal i…
A non-monotone trust-region method with noisy oracles and additional sampling
Natasa Krejic, Natasa Krklec Jerinkic, Angeles Martinez +1
In this work, we introduce a novel stochastic second-order method, within the framework of a non-monotone trust-region approach, for solving the unconstrained, nonlinear, and non-c…
