Subgradient Methods for Nonsmooth Sample Average Approximation
Xi Chen, Ouqi Fu, Jiyuan Tu +1
We study direct subgradient methods for nonsmooth sample average approximation (SAA). Subgradient descent and Nesterov acceleration with constant step sizes attain polynomial and g…
-admissible processes and noncommutative weighted ergodic theorems
Morgan O'Brien
In this article, we study the bilaterally almost uniform (b.a.u.) convergence of weighted averages of a positive Dunford-Schwartz operator acting on the noncommutative -sp…
A noncommutative weak type maximal inequality for modulated ergodic averages with general weights
Morgan O'Brien
In this article, we prove a weak type maximal inequality, , for weighted averages of a positive Dunford-Schwarz operator acting on a noncommutative -sp…
Noncommutative Wiener-Wintner type ergodic theorems
Morgan O'Brien
In this article, we obtain a version of the noncommutative Banach Principle suitable to prove Wiener-Wintner type results for weights in W1-space. This is used to obtain noncommuta…
Some noncommutative subsequential weighted individual ergodic theorems
Morgan O'Brien
This article is devoted to studying individual ergodic theorems for subsequential weighted ergodic averages on the noncommutative Lp-spaces associated to a semifinite von Neumann a…
