Let us consider a directed, latent-variable model over observed variables X and latent variables Z. In a normalizing flow model, the mapping between Z and X, given by fθ: Rn → Rn, is deterministic and invertible such that X = fθ(Z) and Z = f − 1θ (X) 1. Using change of variables, the ...

WebA normalizing flow is a vector-valued invertible mapping f(x) : RD!RDthat normalizes the distribution of x to a “standard” distribution (or called base distribution). This distribution is usually taken to be an isotropic Gaussian or other ones that are easy to sample from and whose density is easy to evaluate.
