New proof establishes mirror descent convergence for non-convex problems

Researchers have established a convergence proof for mirror descent in non-convex optimization problems, specifically addressing scenarios where boundary limits are not excluded. The proof relies on a novel metric-flattening reparameterization that allows for a definable boundary extension. This framework, when applied to objectives involving Shannon entropy, Fermi--Dirac entropy, and power kernels, demonstrates convergence to a KKT point. Future work aims to extend this methodology to broader Bregman-type algorithms and more complex constraint geometries. AI

    Establishing Boundary KKT Convergence of Mirror Descent through Reparameterization

    arXiv:2608.07248v1 Announce Type: cross Abstract: We prove that mirror descent converges to a KKT point for the nonconvex problem without excluding boundary limits. The result holds under verifiable conditions that jointly couple the objective, the Legendre kernel, and the feasib…
