Webplog(p=q)+(1 p)log((1 p)=(1 q)) is the KL-divergence between Bernoulli distributions. Corollary 4, which is proven in Appendix C, states that PM-DMED-Hinge attains the optimal regret of the N-armed bandit if we run it on an N-armed bandit game represented as partial monitoring. Asymptotic analysis: it is Theorem 6 where we lose the finite-time ...
