A Diffusive Classification Loss for Learning Energy-based Generative Models
Researchers have introduced a new method called Diffusive Classification (DiffCLF) to improve the training of energy-based generative models. This technique reframes the learning process as a supervised classification task across different noise levels, making it more computationally efficient and less prone to mode blindness compared to existing methods like direct maximum likelihood or score matching. The DiffCLF objective can be integrated with standard score-based approaches, and experiments show it leads to higher fidelity and broader applicability for tasks such as compositional sampling and Boltzmann Generator sampling.
