This research introduces Contextual Inverse Reinforcement Learning (COIRL) to learn context-dependent reward functions from expert demonstrations in Contextual Markov Decision Processes. It enables agents to achieve zero-shot transfer to new contexts and showed high action-matching accuracy (83.74%) on real-world sepsis treatment data compared to other methods.
Key insights
- The COIRL framework effectively extends IRL to contextual settings, offering a more efficient and generalizable approach compared to augmenting state spaces or using Behavioral Cloning.
- Learning context-dependent reward functions can be formulated as a convex optimization problem, allowing for theoretically grounded subgradient-based and cutting-plane solutions.
- Zero-shot generalization to unseen contexts is achievable, enabling robust decision-making in dynamic, personalized environments without requiring re-planning or re-training.
