Researchers have developed a novel two-stage framework to improve online reinforcement learning by leveraging offline data. The first stage learns upper and lower bounds on value functions from offline datasets, while the second stage integrates these learned bounds into online algorithms. This data-driven approach offers more flexible and tighter approximations than fixed shaping functions, providing theoretical guarantees for regret reduction and demonstrating significant improvements in empirical results on tabular MDPs.
