Compress to Remember: Learning Compact Memory via On-Policy Distillation for Long Video Generation

Xiaoyu Wu, Weihang Guo, Yifei Wang +3

Standard video generators do not natively compact historical context into reusable memory tokens. As generation continues, the growing history makes it increasingly difficult to re…

Representation by Design in Generation: Cross-View Class-Token Alignment in Diffusion Transformers

Xiaoyu Wu, Yifei Wang, Chen Wei

Generative and representation learning remain asymmetrically connected: semantic representations are used to improve diffusion generation, whereas the models' own representations a…

Taming Outlier Tokens in Diffusion Transformers

Xiaoyu Wu, Yifei Wang, Tsu-Jui Fu +3

We study outlier tokens in Diffusion Transformers (DiTs) for image generation. Prior work has shown that Vision Transformers (ViTs) can produce a small number of high-norm tokens t…

Masked Auto-Regressive Variational Acceleration: Fast Inference Makes Practical Reinforcement Learning

Yuxuan Gu, Weimin Bai, Yifei Wang +2

Masked auto-regressive diffusion models (MAR) benefit from the expressive modeling ability of diffusion models and the flexibility of masked auto-regressive ordering. However, vani…

Uni-Instruct: One-step Diffusion Model through Unified Diffusion Divergence Instruction

Yifei Wang, Weimin Bai, Colin Zhang +3

In this paper, we unify more than 10 existing one-step diffusion distillation approaches, such as Diff-Instruct, DMD, SIM, SiD, -distill, etc, inside a theory-driven framework w…
