OmniSparse: Training-Aware Fine-Grained Sparse Attention for Long-Video MLLMs

Feng Chen, Yefei He, Shaoxuan He +9

Existing sparse attention methods primarily target inference-time acceleration by selecting critical tokens under predefined sparsity patterns. However, they often fail to bridge t…

ACT as Human: Multimodal Large Language Model Data Annotation with Critical Thinking

Lequan Lin, Dai Shi, Andi Han +7

Supervised learning relies on high-quality labeled data, but obtaining such data through human annotation is both expensive and time-consuming. Recent work explores using large lan…

Neighboring Autoregressive Modeling for Efficient Visual Generation

Yefei He, Yuanyu He, Shaoxuan He +4

Visual autoregressive models typically adhere to a raster-order ``next-token prediction" paradigm, which overlooks the spatial and temporal locality inherent in visual content. Spe…

ZipAR: Parallel Auto-regressive Image Generation through Spatial Locality

Yefei He, Feng Chen, Yuanyu He +4

In this paper, we propose ZipAR, a training-free, plug-and-play parallel decoding framework for accelerating auto-regressive (AR) visual generation. The motivation stems from the o…

Evaluating and Advancing Multimodal Large Language Models in Perception Ability Lens

Feng Chen, Chenhui Gou, Jing Liu +6

As multimodal large language models (MLLMs) advance rapidly, rigorous evaluation has become essential, providing further guidance for their development. In this work, we focus on a…
