Abstract

In this talk, we revisit the differentiability and Lipschitz continuity properties of the gradient of the high-order Moreau envelope for nonsmooth convex functions. Leveraging these insights, we propose an inexact gradient method and explore its convergence under mild conditions. Additionally, we establish the global convergence of the method by leveraging the Kurdyka-Lojasiewicz inequality. We illustrate the effectiveness of our approach through both theoretical analyses and numerical results.
