Single-loop Projection-free and Projected Gradient-based Algorithms for Nonconvex-concave Saddle Point Problems with Bilevel Structure
Mohammad Mahdi Ahmadi, Erfan Yazdandoost Hamedani
In this paper, we explore a broad class of constrained saddle point problems with a bilevel structure, wherein the upper-level objective function is nonconvex-concave and smooth ov…

A Stochastic Variance-reduced Accelerated Primal-dual Method for Finite-sum Saddle-point Problems
Erfan Yazdandoost Hamedani, Afrooz Jalilzadeh
In this paper, we propose a variance-reduced primal-dual algorithm with Bregman distance for solving convex-concave saddle-point problems with finite-sum structure and nonbilinear…
