When Token Pruning is Worse than Random: Understanding Visual Token Information in VLLMs

CVPR 2026

Vision Large Language Models (VLLMs) incur high computational costs due to their reliance on hundreds of visual tokens to represent images. While token pruning offers a promising solution for accelerating inference, this paper, however, identifies a key observation: in deeper layers (e.g., beyond th

Mutually Guided Few-Shot Learning For Relational Triple Extraction

ICASSP 2023accepted

Knowledge graphs (KGs), containing many entity-relation-entity triples, provide rich information for downstream applications. Although extracting triples from unstructured texts has been widely explored, most of them require a large number of labeled instances. The performance will drop dramatically…
