Dueling registries?: an alternative perspective and the case for competitive collaboration.
In his commentary, “Duelin’ Registries,” published in this issue of Circulation: Cardiovascular Quality and Outcomes, Oetgen1 argues that the country would benefit if the American College of Cardiology (ACC) and the American Heart Association (AHA) were to combine efforts and resources to collaborate on a single ambulatory (outpatient) cardiovascular registry rather than to continue independent...
متن کاملCopeland Dueling Bandits
A version of the dueling bandit problem is addressed in which a Condorcet winner may not exist. Two algorithms are proposed that instead seek to minimize regret with respect to the Copeland winner, which, unlike the Condorcet winner, is guaranteed to exist. The first, Copeland Confidence Bound (CCB), is designed for small numbers of arms, while the second, Scalable Copeland Bandits (SCB), works...
متن کاملContextual Dueling Bandits
We consider the problem of learning to choose actions using contextual information when provided with limited feedback in the form of relative pairwise comparisons. We study this problem in the dueling-bandits framework of Yue et al. (2009), which we extend to incorporate context. Roughly, the learner’s goal is to find the best policy, or way of behaving, in some space of policies, although “be...
متن کاملSparse Dueling Bandits
The dueling bandit problem is a variation of the classical multi-armed bandit in which the allowable actions are noisy comparisons between pairs of arms. This paper focuses on a new approach for finding the “best” arm according to the Borda criterion using noisy comparisons. We prove that in the absence of structural assumptions, the sample complexity of this problem is proportional to the sum ...
متن کاملDueling Bandits with Weak Regret
We consider online content recommendation with implicit feedback through pairwise comparisons, formalized as the so-called dueling bandit problem. We study the dueling bandit problem in the Condorcet winner setting, and consider two notions of regret: the more well-studied strong regret, which is 0 only when both arms pulled are the Condorcet winner; and the less well-studied weak regret, which...
