When and Where to Look: Adaptive Visual Evidence Scheduling for Efficient Long Video Understanding

Ke Li, Jiayu Chen, Maoliang Li +5

Efficient long-video understanding requires vision--language models (VLMs) to reason over a small number of frames selected as sparse visual evidence. Existing relevance-based meth…

Token Radius Attention for Efficient Video Generation

Jiayu Chen, Zhikun Jiang, Maoliang Li +6

Video Diffusion Transformers (VDiTs) enable high-fidelity generation but incur quadratic cost from dense 3D self-attention. Existing head- and block-level sparse methods share comp…

EcoVideo: Entropy-Orchestrated Video Generation Paradigm in Cloud-Edge Dynamics

Jiayu Chen, Hengyi Zhang, Maoliang Li +5

DiT video generation is latency-intensive due to iterative full-frame denoising, while prior cloud-edge methods largely rely on static inter-step decoupling and cannot leverage int…
