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
IMPACT Temporal resampling in clinical RL can lead to performance degradation and misleading evaluations, posing risks for patient care.
