Adaptive Restart of the Optimized Gradient Method for Convex Optimization [PDF]

open access: yesJournal of Optimization Theory and Applications, 2017
First-order methods with momentum such as Nesterov's fast gradient method are very useful for convex optimization problems, but can exhibit undesirable oscillations yielding slow convergence rates for some applications.

A Proximal Stochastic Gradient Method with Progressive Variance Reduction [PDF]

open access: yesSIAM Journal on Optimization, 2014
We consider the problem of minimizing the sum of two convex functions: one is the average of a large number of smooth component functions, and the other is a general convex function that admits a simple proximal mapping.

Gradient methods with memory [PDF]

open access: yesOptimization Methods and Software, 2021
In this paper, we consider gradient methods for minimizing smooth convex functions, which employ the information obtained at the previous iterations in order to accelerate the convergence towards the optimal solution. This information is used in the form of a piece-wise linear model of the objective function, which provides us with much better ...

Optimizing Static Linear Feedback: Gradient Method [PDF]

open access: yesSIAM Journal of Control and Optimization, 2020
The linear quadratic regulator is the fundamental problem of optimal control. Its state feedback version was set and solved in the early 1960s. However static output feedback problem has no explicit-form solution.
