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…

$T$ -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 $T$ acting on the noncommutative $L_{p}$ -sp…
