What is ddpm-ema-celebahq-256?
DDPM-EMA-CelebAHQ-256 is a state-of-the-art diffusion model designed for high-quality face image generation. Built on the Denoising Diffusion Probabilistic Models framework, it leverages a weighted variational bound and incorporates EMA (Exponential Moving Average) for stable training. The model is specifically trained on the CelebA-HQ dataset to generate 256x256 pixel face images.
Implementation Details
The model implements a progressive lossy decompression scheme that can be interpreted as a generalization of autoregressive decoding. It supports multiple noise scheduling options including DDPM, DDIM, and PNDM, offering different trade-offs between quality and inference speed.
- DDPM scheduler: Highest quality but slower inference
- DDIM scheduler: Balanced quality-speed trade-off
- PNDM scheduler: Faster inference option
Core Capabilities
- High-quality 256x256 face image generation
- Flexible scheduling options for different use cases
- Progressive decompression capabilities
- Simple integration through the diffusers library
Frequently Asked Questions
Q: What makes this model unique?
