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.

Adversarial Diffusion Distillation

4 code implementations28 Nov 2023 Axel Sauer, Dominik Lorenz, Andreas Blattmann, Robin Rombach

We introduce Adversarial Diffusion Distillation (ADD), a novel training approach that efficiently samples large-scale foundational image diffusion models in just 1-4 steps while maintaining high image quality.

StyleGAN-T: Unlocking the Power of GANs for Fast Large-Scale Text-to-Image Synthesis

1 code implementation23 Jan 2023 Axel Sauer, Tero Karras, Samuli Laine, Andreas Geiger, Timo Aila

Text-to-image synthesis has recently seen significant progress thanks to large pretrained language models, large-scale training data, and the introduction of scalable model families such as diffusion and autoregressive models.

Counterfactual Generative Networks

1 code implementation ICLR 2021 Axel Sauer, Andreas Geiger

Prior works on image classification show that instead of learning a connection to object shape, deep classifiers tend to exploit spurious correlations with low-level texture or the background for solving the classification task.

How to Make Deep RL Work in Practice

1 code implementation25 Oct 2020 Nirnai Rao, Elie Aljalbout, Axel Sauer, Sami Haddadin

Additionally, techniques from supervised learning are often used by default but influence the algorithms in a reinforcement learning setting in different and not well-understood ways.

Conditional Affordance Learning for Driving in Urban Environments

1 code implementation18 Jun 2018 Axel Sauer, Nikolay Savinov, Andreas Geiger

Most existing approaches to autonomous driving fall into one of two categories: modular pipelines, that build an extensive model of the environment, and imitation learning approaches, that map images directly to control outputs.
