Dual space preconditioning for gradient descent
The conditions of relative smoothness and relative strong convexity were recently introduced for the analysis of Bregman gradient methods for convex optimization. We introduce a generalized left-preconditioning method for gradient descent and show that its convergence on an essentially smooth convex...
