Principle:AUTOMATIC1111 Stable diffusion webui VQ VAE Quantization

Definition

Vector quantization layer for VQ-VAE latent space discretization.

Motivation

Vector quantization maps continuous latent representations to a fixed codebook of discrete embeddings, which is essential for VQ-VAE models to maintain a structured and compact latent space. This discretization step enables efficient storage, retrieval, and manipulation of latent codes within the image generation and upscaling pipelines.
