Fast High-Resolution Image Synthesis with Latent Adversarial Diffusion Distillation

no code implementations18 Mar 2024 Axel Sauer, Frederic Boesel, Tim Dockhorn, Andreas Blattmann, Patrick Esser, Robin Rombach

Distillation methods, like the recently introduced adversarial diffusion distillation (ADD) aim to shift the model from many-shot to single-step inference, albeit at the cost of expensive and difficult optimization due to its reliance on a fixed pretrained DINOv2 discriminator.

Align your Latents: High-Resolution Video Synthesis with Latent Diffusion Models

2 code implementations CVPR 2023 Andreas Blattmann, Robin Rombach, Huan Ling, Tim Dockhorn, Seung Wook Kim, Sanja Fidler, Karsten Kreis

We first pre-train an LDM on images only; then, we turn the image generator into a video generator by introducing a temporal dimension to the latent space diffusion model and fine-tuning on encoded image sequences, i. e., videos.

Latent Space Diffusion Models of Cryo-EM Structures

no code implementations25 Nov 2022 Karsten Kreis, Tim Dockhorn, Zihao Li, Ellen Zhong

The state-of-the-art method cryoDRGN uses a Variational Autoencoder (VAE) framework to learn a continuous distribution of protein structures from single particle cryo-EM imaging data.

Differentially Private Diffusion Models

1 code implementation18 Oct 2022 Tim Dockhorn, Tianshi Cao, Arash Vahdat, Karsten Kreis

While modern machine learning models rely on increasingly large training datasets, data is often limited in privacy-sensitive domains.

GENIE: Higher-Order Denoising Diffusion Solvers

1 code implementation11 Oct 2022 Tim Dockhorn, Arash Vahdat, Karsten Kreis

Synthesis amounts to solving a differential equation (DE) defined by the learnt model.

Score-Based Generative Modeling with Critically-Damped Langevin Diffusion

1 code implementation ICLR 2022 Tim Dockhorn, Arash Vahdat, Karsten Kreis

SGMs rely on a diffusion process that gradually perturbs the data towards a tractable distribution, while the generative model learns to denoise.
