Stream4D: 4D-Consistency for Streaming Autoregressive Diffusion Video Models

Yuanhao Ban, Jiaqi Feng, Hengguang Zhou +3

Streaming autoregressive diffusion models enable real-time, long-horizon video generation, but their training objectives optimize local frame prediction rather than the geometry an…

Differentiable Efficient Operator Search

Xiaohuan Pei, Jiyuan Zhang, Yuanfan Guo +4

Efficient multimodal foundation models often rely on manually designed token-reduction operators, such as pruning, merging, pooling, and adaptive reweighting. Although these operat…

Rethinking Causal Mask Attention for Vision-Language Inference

Xiaohuan Pei, Tao Huang, YanXiang Ma +1

Causal attention has become a foundational mechanism in autoregressive vision-language models (VLMs), unifying textual and visual inputs under a single generative framework. Howeve…
