Webb24 okt. 2024 · In this paper, we consider first-order convergence theory and algorithms for solving a class of non-convex non-concave min-max saddle-point problems, whose objective function is weakly convex in the variables of minimization and weakly concave in the variables of maximization. It has many important applications in machine learning … Webbexact proximal point method is analyzed in Section 2. Section 3 is concerned with known applications of the proximal regularization to nonconvex problems and describes the …

Wasserstein distance plays increasingly important roles in machine learning, stochastic programming and image processing. Major efforts have been under way to address its high computational … Webb17 maj 2024 · The proximal point method (PPM) is a fundamental method in optimization that is often used as a building block for designing optimization algorithms. In this work, we use the PPM method to provide conceptually simple derivations along with convergence analyses of different versions of Nesterov's accelerated gradient method (AGM). The key … WebbIncremental methods play an important role in large-scale optimization problems such as the train-ing of deep neural networks. In this paper, we study a family of incremental methods, including incremental (sub)-gradient, proximal point, and prox-linear methods.
