论文摘要
我们提出了两个polyak型台阶尺寸以进行镜下下降，并证明它们的收敛量以最大程度地减少局部Lipschitz函数。与原始Polyak步长不同，两个步骤尺寸都不需要目标函数的最佳值。
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.
