Sparse Attention for Video Generation Acceleration via Growing Sparsity and Reduced Search
Yun Dai, Yuyun Chen, Jiarui Wen +3
Diffusion Transformers (DiTs) dominate video generation but suffer from high inference cost due to the quadratic complexity of self-attention. Sparse attention mitigates this by sk…

PARK: Accurate Block Retrieval for Sparse Attention in Video Diffusion Transformers
Yun Dai, Jiarui Wen, Huiping Zhuang +2
Diffusion Transformers (DiTs) have become a dominant architecture for video generation, but their efficiency is limited by the quadratic complexity of full attention. Sparse attent…
