Accelerated Stochastic Algorithms for Convex-Concave Saddle-Point Problems
Mathematics of Operations Research, 2021 We develop stochastic first-order primal-dual algorithms to solve a class of convex-concave saddle-point problems. When the saddle function is strongly convex in the primal variable, we develop the first stochastic restart scheme for this problem.

Journal of NeuroEngineering and Rehabilitation, 2021 Introduction After a stroke, a wide range of deficits can occur with varying onset latencies. As a result, assessing impairment and recovery are enormous challenges in neurorehabilitation. Although several clinical scales are generally accepted, they are

Leakage threshold of a saddle point
Tribology Letters, 2022 Abstract The threshold condition for leakage inception is of great interest to many engineering applications, and it is essential for seal design. In the current study, the leakage threshold is studied by means of a numerical method for a mechanical contact problem between an elastic bisinusoidal surface and a rigid flat surface.

Exact QFT duals of AdS black holes
Journal of High Energy Physics, 2023 We construct large N saddle points of the matrix model for the N $$ \mathcal{N} $$ = 4 Yang- Mills index dual to the BPS black holes in AdS 5 × S 5, in two different setups.

Zeroth-Order Algorithms for Smooth Saddle-Point Problems [PDF]
Communications in Computer and Information Science, 2020 In recent years, the importance of saddle-point problems in machine learning has increased. This is due to the popularity of GANs. In this paper, we solve stochastic smooth (strongly) convex-concave saddle-point problems using zeroth-order oracles ...

A Primal-Dual Algorithm with Line Search for General Convex-Concave Saddle Point Problems
SIAM Journal on Optimization, 2020 In this paper, we propose a primal-dual algorithm with a novel momentum term using the partial gradients of the coupling function that can be viewed as a generalization of the method proposed by Chambolle and Pock in 2016 to solve saddle point problems ...
