These models realize generative trajectories ... WebA Poisson flow can be viewed as a type of continuous normalizing flows [4, 10, 33] in the sense that it continuously maps between an arbitrary distribution and an easily sampled one: in the previous works an N -dimensional Gaussian and in PFGM a uniform distribution on an N -dimensional hemisphere.
