Convergence of Proximal Point and Extragradient-Based Methods Beyond Monotonicity: the Case of Negative Comonotonicity
Eduard Gorbunov, Adrien Taylor, Samuel Horváth +1
Algorithms for min-max optimization and variational inequalities are often studied under monotonicity assumptions. Motivated by non-monotone machine learning applications, we follo…

Stochastic Distributed Learning with Gradient Quantization and Variance Reduction
Samuel Horváth, Dmitry Kovalev, Konstantin Mishchenko +2
We consider distributed optimization where the objective function is spread among different devices, each sending incremental model updates to a central server. To alleviate the co…
