New Q-learning algorithm tackles mean-field control with Wasserstein uncertainty

Researchers have developed a robust Q-learning algorithm designed for mean-field control problems. This algorithm specifically addresses scenarios with Wasserstein uncertainty in common noise laws. It combines a quantization-and-projection scheme with a Wasserstein dual reformulation, and the paper establishes convergence guarantees and finite-time iteration bounds for both synchronous and asynchronous learning methods. Numerical experiments demonstrate the algorithm's performance on systemic risk and epidemic models, highlighting its robustness to common-noise misspecification. AI
