Balance Equation-based Distributionally Robust Offline Imitation Learning

The introduction of Balance Equation-based Distributionally Robust Offline Imitation Learning marks a significant advancement in the field of imitation learning, particularly for robotic and control tasks. Traditional imitation learning methods often assume that environment dynamics remain unchanged, a premise that is frequently violated in real-world applications due to various factors such as modeling inaccuracies and adversarial perturbations. This new framework tackles these challenges by formulating a distributionally robust optimization problem that accounts for uncertainties in transition models. By focusing on learning robust policies solely from expert demonstrations, the framework eliminates the need for additional environment interactions, thus streamlining the learning process. Empirical evaluations have shown that this approach outperforms state-of-the-art offline imitation learning baselines, demonstrating superior robustness and generalization capabilities. As such, this…
