FocusDiT: Masking Queries in Diffusion Transformers for Fine-grained Image Generation

Xueji Fang, Liyuan Ma, Jianhao Zeng +3

Diffusion transformer (DiT) has been widely adopted in the generative diffusion field, advancing the denoising of query tokens through attention and Feed-Forward (\text{FFN}) layer…

Equilibrated Diffusion: Frequency-aware Textual Embedding for Equilibrated Image Customization

Liyuan Ma, Xueji Fang, Guo-Jun Qi

Image customization learns target subjects from reference concept images and generates conditioned images per text prompts, mainly modifying styles or backgrounds. Prevailing metho…

Traj2Action: A Co-Denoising Framework for Trajectory-Guided Human-to-Robot Skill Transfer

Han Zhou, Jinjin Cao, Liyuan Ma +2

Learning diverse manipulation skills for real-world robots is severely bottlenecked by the reliance on costly and hard-to-scale teleoperated demonstrations. While human videos offe…

Reinforcing the Diffusion Chain of Lateral Thought with Diffusion Language Models

Zemin Huang, Zhiyang Chen, Zijun Wang +2

We introduce the Diffusion Chain of Lateral Thought (DCoLT), a reasoning framework for diffusion language models. DCoLT treats each intermediate step in the reverse diffusion proce…

When Images Speak Louder: Mitigating Language Bias-induced Hallucinations in VLMs through Cross-Modal Guidance

Jinjin Cao, Zhiyang Chen, Zijun Wang +3

Vision-Language Models (VLMs) have shown solid ability for multimodal understanding of both visual and language contexts. However, existing VLMs often face severe challenges of hal…

Don't Settle Too Early: Self-Reflective Remasking for Diffusion Language Models

Zemin Huang, Yuhang Wang, Zhiyang Chen +1

Mask-based Diffusion Language Models (DLMs) struggle to revise incorrect tokens: once a token is generated, it typically remains fixed. The key challenge is to identify potential e…
