Safe Linear Bandits over Unknown Polytopes

no code implementations27 Sep 2022 Aditya Gangrade, Tianrui Chen, Venkatesh Saligrama

We then analyse a natural doubly-optimistic strategy for the safe linear bandit problem, DOSS, which uses optimistic estimates of both reward and safety risks to select actions, and show that despite the lack of knowledge of constraints or feasible points, DOSS simultaneously obtains tight instance-dependent $O(\log^2 T)$ bounds on efficacy regret, and $\tilde O(\sqrt{T})$ bounds on safety violations.

Strategies for Safe Multi-Armed Bandits with Logarithmic Regret and Risk

no code implementations1 Apr 2022 Tianrui Chen, Aditya Gangrade, Venkatesh Saligrama

We investigate a natural but surprisingly unstudied approach to the multi-armed bandit problem under safety risk constraints.
