"Web1 de fev. de 2024 · The variational auto-encoder (VAE) is a generative model originally introduced in the work of Kingma and Welling (2013). Given some data of interest, represented as a vector x ∈ R w, a VAE computes a representation of x (a “code”) in the form of a vector z ∈ R l, such that x can be accurately reconstructed from z.
