An overview on VQ-VAE: Learning Discrete Representation Space

WebIn machine learning, the expressions "hidden (or latent) space" and "embedding space" occur in several contexts. More specifically, an embedding can refer to a vector representation of a word. An embedding space can refer to a subspace of a bigger space, so we say that the subspace is embedded in the bigger space.
