@838959823 There are several similar concurrent works regrading Rectified Flow:

• Liu et al., Flow Straight and Fast: Learning to Generate and Transfer Data with Rectified Flow
• Lipman et al., Flow Matching for Generative Modeling
• Albergo and Vanden-Eijnden, Building Normalizing Flows with Stochastic Interpolants
• Heitz et al., Iterative α-(de)Blending: Learning a Deterministic Mapping Between Arbitrary Densities
