Researchers have introduced a new class of diffusion-based stochastic particle optimization methods designed for loss functions with intractable gradients. These methods are particularly applicable to training generative models, fine-tuning, and learning latent-variable models. The proposed approach, termed mean-field dynamics and its interacting-particle approximations, encompasses existing algorithms and offers a pathway to novel techniques. Theoretical analysis demonstrates exponential convergence under specific assumptions, with practical evaluations showcasing momentum and higher-order Langevin variants applied to maximum marginal-likelihood estimation and energy-based-model training.
