Abstract

We use smoothing processes based on the infimal convolution of convex, proper and lower semi-continuous functions to regularise optimization problems given by convex-composite functions. We show that the proposed regularisation schemes still (epi-)converge to the original data, even if the chosen kernel is an arbitrary convex function. This also allows to derive upper estimates of the subdifferentials of the epi-limits of non-convex functions without using qualifying conditions (namely BCQ-type conditions).
