CyFM: Cylindrical Optimal Transport for Few-Step Complex-Valued Flow Matching
Cylindrical Flow Matching is formulated to strictly bound the angular regression target, coupling noise and data via exact minibatch Optimal Transport jointly over whole fields jointly over whole fields, and achieves lower generative error than the best Cartesian baseline at every step up to $k = 8$ on synthetic fields...
