ADMM Training Algorithms for Residual Networks: Convergence, Complexity and Parallel Training

no code implementations23 Oct 2023 Jintao Xu, Yifei Li, Wenxun Xing

Convergence of the proximal point version is proven based on a Kurdyka-Lojasiewicz (KL) property analysis framework, and we can ensure a locally R-linear or sublinear convergence rate depending on the different ranges of the Kurdyka-Lojasiewicz (KL) exponent, in which a necessary auxiliary function is constructed to realize our goal.
