Provable Parameter-Free Fixed-Point Algorithms with Linear Convergence Rates
Quoc Tran-Dinh, Pham Ngoc Anh, Ha Manh Tien
In this paper, we develop provable parameter-free and adaptive fixed-point algorithms for contractive mappings, with an emphasis on automatically exploiting hidden contractivity wi…
Adaptive Regularization within Trust Region Methods for Stochastic Nonconvex Optimization
Yunsoo Ha, Sara Shashaani, Quoc Tran-dinh
We propose a stochastic nonconvex optimization algorithm that achieves almost sure iteration complexity for problems with smooth objective functions…
A Class of Accelerated Fixed-Point-Based Methods with Delayed Inexact Oracles and Its Applications
Nghia Nguyen-Trung, Quoc Tran-Dinh
In this paper, we develop a novel accelerated fixed-point-based framework using delayed inexact oracles to approximate a fixed point of a nonexpansive operator (or equivalently, a…
New Accelerated Past-Extragradient Methods with Variance Reduction for Generalized Equations
Quoc Tran-Dinh, Nghia Nguyen-Trung
We develop a novel past-extragradient-type algorithmic framework, combining both Nesterov's \textit{acceleration} and \textit{variance-reduction} techniques, to solve a class of ge…
Variance-Reduced Fast Operator Splitting Methods for Generalized Equations
Quoc Tran-Dinh
We develop two variance-reduced fast operator splitting methods to approximate solutions of a class of generalized equations, covering fundamental problems such as \rvs{minimizatio…
Complexity of Linearized Perturbed Augmented Lagrangian Methods for Nonsmooth Nonconvex Optimization with Nonlinear Equality Constraints
Lahcen El Bourkhissi, Ion Necoara, Panagiotis Patrinos +1
This paper addresses a class of general nonsmooth and nonconvex composite optimization problems subject to nonlinear equality constraints. We assume that a part of the objective fu…
