OPTAMI: Global Superlinear Convergence of High-order Methods

Dmitry Kamzolov, Dmitry Pasechnyuk, Artem Agafonov +2

Second-order methods for convex optimization outperform first-order methods in terms of theoretical iteration convergence, achieving rates up to $O (k^{- 5})$ for highly-smooth funct…

Exploring Jacobian Inexactness in Second-Order Methods for Variational Inequalities: Lower Bounds, Optimal Algorithms and Quasi-Newton Approximations

Artem Agafonov, Petr Ostroukhov, Roman Mozhaev +5

Variational inequalities represent a broad class of problems, including minimization and min-max problems, commonly found in machine learning. Existing second-order and high-order…
