Our new preprint with Taha El Bakkali El Kadi, Acceleration Survives Heavy Tails and Generalized Smoothness, establishes high-probability accelerated convergence guarantees for convex optimization under heavy-tailed noise and generalized smoothness.
I was recognized as a Top Area Chair (Top AC) at NeurIPS 2026 for my service as an Area Chair.
Our new preprint with Yuki Takezawa, Last-Iterate Convergence Rate of Normalized Gradient Descent under Hölder Smoothness, establishes last-iterate guarantees for convex Hölder-smooth objectives, including an optimal-order rate with a linearly decreasing stepsize.
Egor Shulgin joined the team as a postdoctoral researcher in September 2026.
Our new preprint, What's in a Smoothness Constant? Tighter Rates for Local SGD with Bounded Second-Order Heterogeneity, establishes tighter convergence guarantees and nearly matching lower bounds for Local SGD on general convex objectives under bounded second-order heterogeneity.
Our paper Last Iterate Convergence of AdaGrad-Norm for Convex Non-Smooth Optimization received the Best Application Paper Award at MOTOR 2026.
