A new paper highlights significant risks associated with temporal resampling in clinical reinforcement learning (RL). Researchers found that processing retrospective clinical data into uniform time intervals, a common practice for offline RL, can drastically reduce model performance by up to 60%. This binning method creates a fictional representation of patient scenarios, and retrospective evaluations can falsely indicate improved performance compared to actual deployment. AI
