WebAffine Coupling is a method for implementing a normalizing flow (where we stack a sequence of invertible bijective transformation functions). Affine coupling is one of these bijective transformation functions. Specifically, it is an example of a reversible transformation where the forward function, the reverse function and the log-determinant are …
Web21 de jun. de 2024 · Probabilistic modeling using normalizing flows pt.1. Probabilistic models give a rich representation of observed data and allow us to quantify uncertainty, detect outliers, and perform simulations. Classic probabilistic modeling require us to model our domain with conditional probabilities, which is not always feasible.
Web6 de out. de 2024 · To this end, we propose a novel fully convolutional cross-scale normalizing flow (CS-Flow) that jointly processes multiple feature maps of different scales. Using normalizing flows to assign meaningful likelihoods to input samples allows for efficient defect detection on image-level.
