A Unified Structured Query Understanding Framework for Industrial Semantic Search

Ping Liu, Qianqi Shen, Jianqiang Shen +15

Query understanding in large-scale industrial search systems is typically implemented as a cascade of disparate, task-specific components. While individually optimizable, this frag…

REVEAL: Reference-Grounded Reasoning for Multimodal Manipulation Detection

Jun Zhou, Bingwen Hu, Yaxiong Wang +4

Multimodal manipulation detection aims to simultaneously identify forged image--text pairs and localize tampered regions, yet existing methods typically rely on memorizing isolated…

Where Concept Erasure Should Occur: Concept-Layer Alignment in Text-to-Video Diffusion Models

Yiwei Xie, Ping Liu, Zheng Zhang

Text-to-video diffusion transformers encode semantic information unevenly across model depth, which constrains effective concept erasure. We identify a representational bottleneck,…

Closed-Form Linear-Probe Dataset Distillation for Pre-trained Vision Models

Bincheng Peng, Guang Li, Ping Liu +2

Dataset distillation compresses a large training set into a small synthetic set that preserves downstream training utility. While most existing methods target training networks fro…

PROBE: Diagnosing Residual Concept Capacity in Erased Text-to-Video Diffusion Models

Yiwei Xie, Zheng Zhang, Ping Liu

Concept erasure techniques for text-to-video (T2V) diffusion models report substantial suppression of sensitive content, yet current evaluation is limited to checking whether the t…

Breaking Class Barriers: Efficient Dataset Distillation via Inter-Class Feature Compensator

Xin Zhang, Jiawei Du, Ping Liu +1

Dataset distillation has emerged as a technique aiming to condense informative features from large, natural datasets into a compact and synthetic form. While recent advancements ha…
