| Research Type | Theoretical | We give two new algorithms for this problem in the informed setting. Our best algorithm achieves a pseudo-regret of O(γ(G) 2 3 ), where γ(G) is the domination number of the feedback graph. This significantly improves upon the previous best result for the same problem, which was based on the independence number of G. We also present matching lower bounds for our result that we describe in detail. Finally, we give a new algorithm with improved policy regret bounds when partial counterfactual feedback is available. All proofs of results are deferred to Appendix D. |
