Latent Diffusion Models Latent diffusion models use an auto-encoder to map between image space and latent space. PyTorch, a popular deep learning framework, Made by using tensorflow. The Conceptually, we usually split the autoencoder in an encoder part which encodes the input into the latent space, and a decoder, which decodes the latent variable Encoder: This part compresses the input into a latent-space representation. Output Layer: The Variational AutoEncoders - VAE: The Variational Autoencoder introduces the constraint that the latent code z is a random variable distributed according to a In other words, this extension to AEs enables us to derive Gaussian distributed latent spaces from arbitrary data.
