Upper and lower bounds for the Bregman divergence
In this paper we study upper and lower bounds on the Bregman divergence [Formula: see text] for some convex functional [Formula: see text] on a normed space [Formula: see text] , with subgradient [Formula: see text] . We give a considerably simpler new proof of the inequalities by Xu and Roach for t...
