Active teacher selection for reward learning
Researchers introduce the Hidden Utility Bandit (HUB) framework to address a critical limitation in reward learning systems: their reliance on feedback from a single idealized teacher. The framework models teacher heterogeneity in rationality, expertise, and cost, enabling Active Teacher Selection (ATS) algorithms that strategically choose which teachers to query, demonstrating superior performance in paper recommendation and vaccine testing applications.
