CyFM: Cylindrical Optimal Transport for Few-Step Complex-Valued Flow Matching

Marcel Musiałek, Iga Wolanin, Damian Ryczko +2

Complex-valued signals like MRI and audio spectrograms are typically modelled as flat two-channel Euclidean data. The inherited Euclidean metric $d{A}^2+A^{2}d{\theta }^2$ vanishes at the o…
