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…
An investigation of stochastic trust-region based algorithms for finite-sum minimization
Stefania Bellavia, Benedetta Morini, Simone Rebegoldi
This work elaborates on the TRust-region-ish (TRish) algorithm, a stochastic optimization method for finite-sum minimization problems proposed by Curtis et al. in [Curtis2019, Curt…
Inexact Restoration via random models for unconstrained noisy optimization
Benedetta Morini, Simone Rebegoldi
We study the Inexact Restoration framework with random models for minimizing functions whose evaluation is subject to errors. We propose a constrained formulation that includes wel…
