Moreover, at the step 8 of Algorithm 1, we further use a momentum iteration to update y. When Bregman functions 1 t(x) = 1 2 kxk2 and ˚ t(y) = 2 kyk2 for all t 1, we have D t (x;x t) = 1 2 kx t 2 and D ˚ t (y;y t) = 1 2 y tk 2. Under this case, Algorithm 1 will reduce the standard (stochastic) proximal ...
