Revealing Training Data Exposure in Vision Language Large Models via Parameter Gradients

Zhihao Zhu, Hongyi Tang, Yi Yang +1

Vision-Language Large Models (VLLMs) trained on massive crawled corpora raise pressing copyright and data-provenance concerns. These concerns are particularly acute in healthcare,…

ATLAS: All-round Testing of Long-context Abilities across Scales

Deli Huang, Cunguang Wang, Hongyin Tang +15

Long-context language models now advertise context windows up to millions of tokens, yet evaluations typically report a single length or a narrow task family, masking two failure m…

DistractMIA: Black-Box Membership Inference on Vision-Language Models via Semantic Distraction

Hongyi Tang, Zhihao Zhu, Yi Yang

Vision-language models (VLMs) are trained on large-scale image-text corpora that may contain private, copyrighted, or otherwise sensitive data, motivating membership inference as a…

Efficient Context Scaling with LongCat ZigZag Attention

Chen Zhang, Yang Bai, Jiahuan Li +19

We introduce LongCat ZigZag Attention (LoZA), which is a sparse attention scheme designed to transform any existing full-attention models into sparse versions with rather limited c…

A Preliminary Study on the Promises and Challenges of Native Top- Sparse Attention

Di Xiu, Hongyin Tang, Bolin Rong +4

Large Language Models (LLMs) are increasingly prevalent in the field of long-context modeling, however, their inference computational costs have become a critical bottleneck hinder…

NeedleInATable: Exploring Long-Context Capability of Large Language Models towards Long-Structured Tables

Lanrui Wang, Mingyu Zheng, Hongyin Tang +5

Processing structured tabular data, particularly large and lengthy tables, constitutes a fundamental yet challenging task for large language models (LLMs). However, existing long-c…
