Fast Augmented Lagrangian Method in the convex regime with convergence guarantees for the iterates. [PDF]

open access: yesMath Program, 2023
This work aims to minimize a continuously differentiable convex function with Lipschitz continuous gradient under linear equality constraints. The proposed inertial algorithm results from the discretization of the second-order primal-dual dynamical ...

Pareto front approximation through a multi-objective augmented Lagrangian method

open access: yesEURO Journal on Computational Optimization, 2021
In this manuscript, we consider smooth multi-objective optimization problems with convex constraints. We propose an extension of a multi-objective augmented Lagrangian Method from recent literature.

FairALM: Augmented Lagrangian Method for Training Fair Models with Little Regret. [PDF]

open access: yesComput Vis ECCV, 2020
Algorithmic decision making based on computer vision and machine learning methods continues to permeate our lives. But issues related to biases of these models and the extent to which they treat certain segments of the population unfairly, have led to ...

An accelerated proximal augmented Lagrangian method and its application in compressive sensing [PDF]

open access: yesJournal of Inequalities and Applications, 2017
As a first-order method, the augmented Lagrangian method (ALM) is a benchmark solver for linearly constrained convex programming, and in practice some semi-definite proximal terms are often added to its primal variable’s subproblem to make it more ...

Stochastic inexact augmented Lagrangian method for nonconvex expectation constrained optimization [PDF]

open access: yesComputational optimization and applications, 2022
Many real-world problems not only have complicated nonconvex functional constraints but also use a large number of data points. This motivates the design of efficient stochastic methods on finite-sum or expectation constrained problems. In this paper, we

Moreau Envelope Augmented Lagrangian Method for Nonconvex Optimization with Linear Constraints [PDF]

open access: yesJournal of Scientific Computing, 2021
The augmented Lagrangian method (ALM) is one of the most useful methods for constrained optimization. Its convergence has been well established under convexity assumptions or smoothness assumptions, or under both assumptions.
