arXiv:2606.28307v1 Announce Type: cross Abstract: We analyze Bregman ADMM for nonconvex linearly constrained problems under two-sided relative smoothness, a condition that replaces the standard Lipschitz gradient assumption with a Hessian comparison relative to a Bregman kernel. This setting covers polynomial objectives arising in matrix and tensor models for which a global Lipschitz-gradient constant need not exist. We show that on an invariant open state-space domain, one iteration of Bregman ADMM defines a smooth primal--dual fixed-point map whose strict-saddle KKT points are unstable fixed
This paper tackles a fundamental challenge in optimization for complex AI models by relaxing strong traditional assumptions, indicating continued progress in the theoretical underpinnings of machine learning.
Improved optimization techniques can lead to more efficient and robust training of advanced AI systems, particularly those with non-linear and non-Lipschitz characteristics, expanding the scope of solvable problems.
The theoretical understanding and practical applicability of Bregman ADMM are enhanced, potentially enabling better handling of complex machine learning models beyond current limitations.
