New Gaussian Mixture Model improves DDIM sampling quality

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a new method to improve the sampling process in Denoising Diffusion Implicit Models (DDIM). Their approach utilizes a Gaussian Mixture Model (GMM) as the reverse transition operator, which matches the first and second-order central moments of the DDPM forward marginals. This technique has demonstrated the ability to generate samples of equal or higher quality compared to the original DDIM, particularly when using a small number of sampling steps. AI

IMPACT Enhances sample generation quality and efficiency for diffusion models, potentially improving downstream applications.

    Improved DDIM Sampling with Moment Matching Gaussian Mixtures

    arXiv:2311.04938v5 Announce Type: replace-cross Abstract: We propose using a Gaussian Mixture Model (GMM) as reverse transition operator (kernel) within the Denoising Diffusion Implicit Models (DDIM) framework, which is one of the most widely used approaches for accelerated sampl…
