Awakening Diffusion Transformers: Eliciting Stronger Generation and Understanding via Massive Activation Modulation

Chaofan Gan, Zicheng Zhao, Yuanpeng Tu +6

Massive Activations (MAs) have been widely observed in Transformer-based models, yet their structure and functional roles in Diffusion Transformers (DiTs) remain insufficiently und…

From Priors to Perception: Grounding Video-LLMs in Physical Reality

Zicheng Zhao, Chaofan Gan, Shijie Li +1

Video Large Language Models (Video-LLMs) excel in general video understanding but often base physical judgments on event expectations rather than observations. We find that they no…
