Acceleration of the PDHGM on Partially Strongly Convex Functions
We propose several variants of the primal–dual method due to Chambolle and Pock. Without requiring full strong convexity of the objective functions, our methods are accelerated on subspaces with strong convexity. This yields mixed rates, [Formula: see text] with respect to initialisation and O(1 / N...
