Researchers have developed a new approach for imitation learning within mean-field games that are influenced by common noise. This method aims to enable agents to learn population-aware policies, which are crucial for adapting to aggregate shocks and maintaining equilibrium dynamics. The study proposes two learning objectives and utilizes behavioral cloning and adversarial divergence proxies, providing theoretical bounds on policy exploitability and performance gaps. A numerical framework combining fictitious play and deep learning is introduced to compute these expert population-aware policies, with experiments demonstrating their superiority over unaware policies.
