Adaptive Schauder Stochastic Mirror Descent in Banach Spaces
In this paper, we introduce an adaptive regularization strategy for stochastic mirror descent (SMD) to solve a class of risk functional minimization problems in infinite-dimensional Banach spaces. This regularization strategy centers on using a Schauder basis to construct a nested family of finite-dimensional subspaces...
