Researchers have introduced Second-Order Drifting Models, an advancement in one-step generative models that evolve distributions during training. By incorporating artificial velocity variables into generated samples, these models lift the dynamics into phase space, enabling accelerated second-order dynamics. This approach addresses the slow convergence issues of first-order drifting models, particularly with fine-scale structures, by mitigating spectral stiffness. A new semi-implicit training algorithm has been developed and tested on tasks including synthetic distribution matching, sequential data generation, and robotic control, showing improved convergence and competitive performance.
