Corruption-robust exploration in episodic reinforcement learning
Thodoris Lykouris, Max Simchowitz, Aleksandrs Slivkins +1
We initiate the study of multi-stage episodic reinforcement learning under adversarial corruptions in both the rewards and the transition probabilities of the underlying system ext…
Advancing subgroup fairness via sleeping experts
Avrim Blum, Thodoris Lykouris
We study methods for improving fairness to subgroups in settings with overlapping populations and sequential predictions. Classical notions of fairness focus on the balance of some…
Feedback graph regret bounds for Thompson Sampling and UCB
Thodoris Lykouris, Eva Tardos, Drishti Wali
We study the stochastic multi-armed bandit problem with the graph-based feedback structure introduced by Mannor and Shamir. We analyze the performance of the two most prominent sto…
