Minimax Regret for Partial Monitoring: Infinite Outcomes and Rustichini's Regret
Tor Lattimore
We show that a version of the generalised information ratio of Lattimore and Gyorgy (2020) determines the asymptotic minimax regret for all finite-action partial monitoring games p…

Mirror Descent and the Information Ratio
Tor Lattimore, András György
We establish a connection between the stability of mirror descent and the information ratio by Russo and Van Roy [2014]. Our analysis shows that mirror descent with suitable loss e…

Improved Regret for Zeroth-Order Adversarial Bandit Convex Optimisation
Tor Lattimore
We prove that the information-theoretic upper bound on the minimax regret for zeroth-order adversarial bandit convex optimisation is at most , where $d…
