I-SplineFlow: Learning Monotone Spline Stochastic Interpolant Schedulers for Few-Step Generation
I-SplineFlow is introduced, which parameterizes the scheduler with integrated monotone splines (I-splines), and improves few-step FID over B\'ezier scheduling in most settings, most clearly at the lowest NFEs, and trains in minutes.
