Accelerating Level-Value Adjustment for the Polyak Stepsize Accelerating Level-Value Adjustment for the Polyak Stepsize

The Polyak stepsize has been widely used in subgradient methods for non-smooth convex optimization. However, calculating the stepsize requires the optimal value, which is generally unknown. Therefore, dynamic estimations of the optimal value are usually needed. In this paper, to guarantee convergenc...
