What is ddpm-ema-cat-256?
DDPM-EMA-Cat-256 is a sophisticated diffusion model developed by Google for generating high-quality cat images. Based on the Denoising Diffusion Probabilistic Models framework, it achieves remarkable image synthesis results through a process inspired by nonequilibrium thermodynamics. The model utilizes EMA (Exponential Moving Average) for enhanced stability and generates images at 256x256 resolution.
Implementation Details
The model implements a weighted variational bound training approach, connecting diffusion probabilistic models with denoising score matching and Langevin dynamics. It supports multiple noise schedulers (DDPM, DDIM, PNDM) for inference, offering flexibility between quality and speed.
- DDPM scheduler: Highest quality but slower inference
- DDIM scheduler: Balanced quality-speed trade-off
- PNDM scheduler: Faster inference option
