Title:       Online learning against adaptive adversaries

Abstract: Online learning algorithms are designed to learn even when their  
input is generated by an adversary. The widely-accepted formal definition  
of an online algorithm's ability to learn is the game-theoretic notion of  
regret. However, the standard definition of regret becomes inadequate if  
the adversary is allowed to adapt to the online algorithm's actions. In  
this talk, I will define an alternative notion of policy regret, which  
provides a meaningful way to measure an online algorithm's performance  
against adaptive adversaries. I will show that no bandit algorithm can  
guarantee a sublinear policy regret against an adaptive adversary with  
unbounde...
