Researchers have introduced MFGLab, an open-source PyTorch library that unifies twelve continuous-time generative models under a single variational problem framework. This approach treats models like Continuous Normalizing Flows, OT-Flow, and score-based models as special cases of mean-field games (MFGs). The library allows users to specify models via a composable cost tuple, automatically handling training loops and sampling. Additionally, the paper proposes DI-Flow, a novel cost design incorporating a differentiable entropy functional to enhance mode coverage, and introduces learning-based MFG solvers that outperform neural training on specific tasks.
