arXiv:2606.09115v1 Announce Type: new Abstract: Offline reinforcement learning (RL) offers a path to policy improvement from logged data alone, using historical returns or other measurable outcomes as world feedback. A key difficulty is improving observed behavior without extrapolating beyond what the offline data supports. We propose \emph{counterfactual transport flows}, a source-conditioned trajectory refinement framework for offline decision-making guided by world feedback. Given a low-feedback candidate trajectory, we construct local preference pairs from offline data by retrieving nearby
The continuous advancements in offline reinforcement learning and the push for more robust decision-making from existing data drive the development of novel refinement frameworks like counterfactual transport flows.
This development can significantly improve the ability of AI systems to learn from imperfect historical data, enabling more reliable and conservative decision-making in critical applications without needing costly or risky real-world interactions.
Offline RL systems can now incorporate more nuanced trajectory refinement, leading to more robust policies that extrapolate less beyond the observed data, thereby broadening the applicability of RL in real-world scenarios.
