Note that 1-sel.alpha is the derivative of the scaling operation, thus the Jacobian of this operation is a diagonal matrix with z.shape [1:] entries on the diagonal, thus the Jacobian determinant is simply the product of these diagonal entries which gives rise to. ldj += np.log (1-self.alpa) * np.prod (z.shape [1:])
WebThis was published yesterday: Flow Matching for Generative Modeling. TL;DR: We introduce a new simulation-free approach for training Continuous Normalizing Flows, generalizing the probability paths induced by simple diffusion processes. We obtain state-of-the-art on ImageNet in both NLL and FID among competing methods. Web25 de set. de 2024 · As for the NFs, we used the planar flow conform related work [3, 14] and also experiment with the radial flow. These flows are usually chosen because they are computationally the cheapest transformations that possess the ability to expand and contract the distributions along a direction (planar) or around a specific point (radial).
