Generalized smooth variational inequalities: Methods with adaptive stepsizes
Published in International Conference on Machine Learning (ICML) 2024, 2024
We introduce clipped first-order methods for solving non-monotone generalized smoothn variational inequalities, establishing the first convergence guarantees for gradient descent-ascent, extragarient, and optimistic methods that match or improve upon standard smooth rates. We also propose extragradient method with backtracking line-search that matches the same rates wihtout additional knoledge on the parameters.

Optimizing ($L_0, L_1$)-Smooth Functions by Gradient Methods
Published in ICLR 2025, 2025
Our analysis significantly improves the best-known complexity bounds of gradient method for convex optimization under generalized smoothness and establishes new best-known guarantees for accelerated gradient method.

Generalized Smooth Stochastic Variational Inequalities: Almost Sure Convergence and Convergence Rates
Published in Transactions on Machine Learning Research (accepted with J2C certification, top 10 % contribution), 2025
We show that clipped first-order methods converge a.s. and in expectation to a solution of stochastic variational inequalities without relying on standard smoothness or boundedness assumptions.
