Fast UCB-type algorithms for stochastic bandits with heavy and super heavy symmetric noise

no code implementations10 Feb 2024 Yuriy Dorn, Aleksandr Katrutsa, Ilgam Latypov, Andrey Pudovikov

In this study, we propose a new method for constructing UCB-type algorithms for stochastic multi-armed bandits based on general convex optimization methods with an inexact oracle.

Federated Privacy-preserving Collaborative Filtering for On-Device Next App Prediction

no code implementations5 Feb 2023 Albert Sayapin, Gleb Balitskiy, Daniel Bershatsky, Aleksandr Katrutsa, Evgeny Frolov, Alexey Frolov, Ivan Oseledets, Vitaliy Kharin

Since the data about user experience are distributed among devices, the federated learning setup is used to train the proposed sequential matrix factorization model.
