A new research paper explores the convergence properties of high-order ODE solvers when applied to diffusion probabilistic models. The study, authored by Zhengjiang Lin, introduces and analyzes $p$-th order Runge-Kutta schemes, demonstrating their effectiveness under the assumption of bounded score function derivatives. The findings suggest that the total variation distance between generated and target distributions can be effectively bounded, with numerical experiments supporting the practical applicability of these methods.
