New Causal Imitation Learning Algorithms Outperform Prior Methods on Complex Tasks

Researchers have developed new causal imitation learning (CIL) algorithms, Causal Soft Q Imitation Learning (SQIL) and Causal Inverse soft-Q Learning (IQ-Learn), to address limitations in existing CIL methods when applied to complex, long-horizon tasks. These new algorithms leverage a causal adjustment framework with advanced inverse reinforcement learning objectives, utilizing an efficient approximation of the sequential $\pi$-backdoor criterion. By exploiting the causal structure of continuous control environments, they reduce the adjustment window, leading to significantly improved performance over prior CIL algorithms on confounded, long-horizon tasks, even surpassing expert performance in some cases.
