Web17 de abr. de 2024 · The posterior distribution is constructed through a normalizing flow (NF) which transforms a simple initial probability into a more complex one through a sequence of invertible transformations. Moreover, a novel convolutional normalizing flow (CNF) is developed to improve the time efficiency and capture dependency between layers. Web12 de out. de 2024 · 1 Answer. Sorted by: 1. 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:])
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).
