Sign Operator for Coping with Heavy-Tailed Noise in Non-Convex Optimization: High Probability Bounds Under $(L_{0}, L_{1})$ -Smoothness

Nikita Kornilov, Philip Zmushko, Andrei Semenov +3

In recent years, non-convex optimization problems are more often described by generalized $(L_{0}, L_{1})$ -smoothness assumption rather than standard one. Meanwhile, severely corrupted…

Efficient randomized algorithms for PageRank problem

Alexander Gasnikov, Denis Dmitriev

In the paper we compare well known numerical methods of finding PageRank vector. We propose Markov Chain Monte Carlo method and obtain a new estimation for this method. We also pro…
