Non-Adversarial Imitation Learning Provably Free of Compounding Errors: The Role of Bellman Constraints

Adversarial imitation learning (AIL) achieves high-quality imitation by mitigating compounding errors in behavioral cloning (BC), but often exhibits training instability due to adversarial optimization. To avoid this issue, a class of non-adversarial Q-based imitation learning (IL) methods, represen…
