Core Concepts
Denoising Diffusion Step-aware Models (DDSM) optimize computational efficiency by adapting network sizes for each generative step.
Abstract
Denoising Diffusion Probabilistic Models (DDPMs) are popular for data generation but face computational bottlenecks.
DDSM introduces adaptive network sizes for each step, reducing redundant computations.
Empirical evaluations show significant computational savings without compromising quality.
DDSM integrates seamlessly with other efficiency-focused models.
Compatibility with existing acceleration techniques like DDIM and latent diffusion.
Experiment results demonstrate effectiveness on various datasets.
Comparison with concurrent work and compatibility with sampling schedulers.
Detailed implementation of slimmable networks and search process.
