Optimal variance-reduced stochastic approximation in Banach spaces
Wenlong Mou, Koulik Khamaru, Martin J. Wainwright +2
We study the problem of estimating the fixed point of a contractive operator defined on a separable Banach space. Focusing on a stochastic query model that provides noisy evaluatio…
