The general idea is to start off with an initial random variable with a
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).
