Data-Driven Upper Confidence Bounds with Near-Optimal Regret for Heavy-Tailed Bandits

Ambrus Tamás, Szabolcs Szentpéteri, Balázs Csanád Csáji

Stochastic multi-armed bandits (MABs) provide a fundamental reinforcement learning model to study sequential decision making in uncertain environments. The upper confidence bounds…

Finite-Sample Identification of Linear Regression Models with Residual-Permuted Sums

Szabolcs Szentpéteri, Balázs Csanád Csáji

This letter studies a distribution-free, finite-sample data perturbation (DP) method, the Residual-Permuted Sums (RPS), which is an alternative of the Sign-Perturbed Sums (SPS) alg…

Signed-Perturbed Sums Estimation of ARX Systems: Exact Coverage and Strong Consistency (Extended Version)

Algo Carè, Erik Weyer, Balázs Cs. Csáji +1

Sign-Perturbed Sums (SPS) is a system identification method that constructs confidence regions for the unknown system parameters. In this paper, we study SPS for ARX systems, and e…

Robust Independence Tests with Finite Sample Guarantees for Synchronous Stochastic Linear Systems

Ambrus Tamás, Dániel Ágoston Bálint, Balázs Csanád Csáji

The paper introduces robust independence tests with non-asymptotically guaranteed significance levels for stochastic linear time-invariant systems, assuming that the observed outpu…
