Two Polyak-Type Step Sizes for Mirror Descent

Optimization and Control 2022-10-05 v1

Abstract

We propose two Polyak-type step sizes for mirror descent and prove their convergences for minimizing convex locally Lipschitz functions. Both step sizes, unlike the original Polyak step size, do not need the optimal value of the objective function.
