Rectified Diffusion: Straightness Is Not Your Need in Rectified Flow
CoRRDiffusion models have greatly improved visual generation but are hindered by slow generation speed due to the computationally intensive nature of solving generative ODEs. Rectified flow, a widely recognized solution, improves generation speed by straightening the ODE path.
