Adapting to Misspecification in Contextual Bandits with Offline Regression Oracles
Sanath Kumar Krishnamurthy, Vitor Hadad, Susan Athey
Computationally efficient contextual bandits are often based on estimating a predictive model of rewards given contexts and arms using past data. However, when the reward model is…
Tractable contextual bandits beyond realizability
Sanath Kumar Krishnamurthy, Vitor Hadad, Susan Athey
Tractable contextual bandit algorithms often rely on the realizability assumption - i.e., that the true expected reward model belongs to a known class, such as linear functions. In…
Survey Bandits with Regret Guarantees
Sanath Kumar Krishnamurthy, Susan Athey
We consider a variant of the contextual bandit problem. In standard contextual bandits, when a user arrives we get the user's complete feature vector and then assign a treatment (a…
