Adaptive Regularization for Nonconvex Optimization Using Inexact Function Values and Randomly Perturbed Derivatives
S. Bellavia, G. Gurioli, B. Morini +1
A regularization algorithm allowing random noise in derivatives and inexact function values is proposed for computing approximate local critical points of any order for smooth unco…
Stochastic Analysis of an Adaptive Cubic Regularisation Method under Inexact Gradient Evaluations and Dynamic Hessian Accuracy
Stefania Bellavia, Gianmarco Gurioli
We here adapt an extended version of the adaptive cubic regularisation method with dynamic inexact Hessian information for nonconvex optimisation in [3] to the stochastic optimisat…
An inexact non stationary Tikhonov procedure for large-scale nonlinear ill-posed problems
Stefania Bellavia, Marco Donatelli, Elisa Riccietti
In this work we consider the stable numerical solution of large-scale ill-posed nonlinear least squares problems with nonzero residual. We propose a non-stationary Tikhonov method…
