SCOPE: Subspace Clustering with Online Per-Head Top-K Estimation for Sparse Video Attention

Qi Zhao, Qirui Li, Hanlin Tang +10

Diffusion Transformers (DiTs) incur quadratic self-attention cost over spatiotemporal tokens. Existing training-free sparse attention methods often construct sparse masks from bloc…

Text Template Tokens Are Implicit Semantic Registers in Diffusion Transformers

Maohua Li, Qirui Li, Yanke Zhou +10

Modern text-to-image diffusion transformers (DiTs) generate images through joint attention, in which text and image tokens interact directly within a single sequence. In large-scal…

Rethinking Cross-Layer Information Routing in Diffusion Transformers

Chao Xu, Maohua Li, Qirui Li +9

Diffusion Transformers (DiTs) have become a de facto backbone of modern visual generation, and nearly every major axis of their design -- tokenization, attention, conditioning, obj…

Linear-DPO: Linear Direct Preference Optimization for Diffusion and Flow-Matching Generative Models

Kesong Li, Yixuan Xu, Kuo-kun Tseng +3

Direct Preference Optimization (DPO) is successful for alignment in LLMs but still faces challenges in text-to-image generation. Existing studies are confined to denoising diffusio…
