Minimax regret bound
Webbound to obtain a regret lower bound for general partial monitoring problems. Second, we propose an algorithm called Partial Monitoring DMED (PM-DMED). We also introduce a slightly modified version of this algorithm (PM-DMED-Hinge) and derive its regret bound. PM-DMED-Hinge is the first algorithm with a logarithmic regret bound for hard problems. Webregret bounds which i) attain a refined dependence on the gaps, as in [13], ii) apply in finite time after a burn-in time only polynomial in S, A, Hand the gaps, iii) depend only …
