Conformal Bandits: Bringing statistical validity and reward efficiency to the small-gap regime

This article likely discusses a new approach to multi-armed bandit problems, focusing on improving performance in scenarios where the differences between the rewards of different actions are small. The use of "conformal" suggests a connection to conformal prediction, potentially offering guarantees on the validity of the chosen actions. The focus on statistical validity and reward efficiency indicates a focus on both the reliability and the speed of learning.
