The package can be easily installed via pip. The basic usage is described here, and a full documentation is available as well. WebWe are ready to introduce normalizing flow models. 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 ...
