N2 - We give an (ε, δ)-differentially private algorithm for the multi-armed bandit (MAB) problem in the shuffle model with a distribution-dependent regret oflog∆aT +k√log δ 1 log T , and a distribution-independent regretO P a∈[k]:∆a>0 ε of O √kT log T +k√log δ 1 log T , where T is the number of rounds, ∆a is the ε suboptimality gap of the arm a, and k is the total number of arms. Our upper bound almost matches the regret of the best known algorithms for the centralized model, and significantly outperforms the best known algorithm in the local model.
