AlphaFlow: Understanding and Improving MeanFlow Models

Huijie Zhang, Aliaksandr Siarohin, Willi Menapace +4

MeanFlow has recently emerged as a powerful framework for few-step generative modeling trained from scratch, but its success is not yet fully understood. In this work, we show that…

Exploring Low-Dimensional Subspaces in Diffusion Models for Controllable Image Editing

Siyi Chen, Huijie Zhang, Minzhe Guo +3

Recently, diffusion models have emerged as a powerful class of generative models. Despite their success, there is still limited understanding of their semantic spaces. This makes i…
