Non-Smooth Weakly-Convex Finite-sum Coupled Compositional Optimization

Quanqi Hu, Dixian Zhu, Tianbao Yang

This paper investigates new families of compositional optimization problems, called $\underline{\mathbf{n}}$on-$\underline{\mathbf{s}}$mooth $\underline{\mathbf{w}}$eakly-$\underline{\mathbf{c}}$onvex…
