- DS-RectFlow at k=2 on the Checkerboard achieves nearly flat SWD from NFE=1 to NFE=20 (range 0.101–0.102), the signature of a fully straightened velocity field. — Divergence-Suppressing Couplings for Rectified Flow
- Under Euler-20 on CIFAR-10, DS-RectFlow achieves a 31% relative FID improvement at NFE=1 and 38% at NFE=20 over vanilla RectFlow. — Divergence-Suppressing Couplings for Rectified Flow
- DS-RectFlow on CelebA-64 with Euler-50 at NFE=2 (FID 4.90) outperforms vanilla RectFlow at every tested NFE in that regime. — Divergence-Suppressing Couplings for Rectified Flow
- Combining DS-RectFlow with adaptive RK45 offline solvers compounds further improvements because the offline correction and offline solver are complementary axes of improvement. — Divergence-Suppressing Couplings for Rectified Flow
- The δ perturbation scale has a unimodal optimal window on CIFAR-10; very small values barely perturb trajectories and very large values produce incoherent couplings with severely degraded FID. — Divergence-Suppressing Couplings for Rectified Flow
- The GMM Crossing result where DS-RectFlow is worse than vanilla at k=1, NFE=1 is a transient effect: cleaner couplings encode transport complexity that one reflow round cannot yet reproduce in a single step, resolved at k=2 or higher NFE. — Divergence-Suppressing Couplings for Rectified Flow
