Researchers have developed a new framework called XPM-WM that significantly improves the efficiency of training cooperative AI agents. This method utilizes a learned World Model (WM) to generate simulated trajectories, which bypasses the need for computationally expensive Mixed-Play trajectories typically required in Population-based Training (PBT) methods like Cross-play Minimization (XPM). By removing this bottleneck and bootstrapping agent training, XPM-WM demonstrates superior sample efficiency and scales linearly with population size, effectively generating diverse and high-performing cooperative agents.
