Researchers have developed a new online learning algorithm called ORUCB designed to improve the correction of expert answers in deferral systems. This algorithm addresses the challenge where early inaccuracies in expert responses can deter valuable queries. ORUCB pools shared and expert-specific polynomial responses, using a bound on cumulative error to calibrate confidence-weighted risk regression and exploration. This allows the system to better decide which answers to purchase, achieving a pseudo-regret of O(sqrt(T log(T+1))) over T rounds under specific conditions. Empirical results on four test streams show that the ORUCB policy has a lower fee-inclusive cost compared to seven baseline methods that do not correct answers. AI
IMPACT This research could lead to more efficient and accurate AI systems that learn from and correct expert inputs, improving decision-making in complex environments.
