On the Robustness of Machine Unlearning for Vision-Language Models

Yujie Lin, Kaidi Jia, Jiayao Ma +2

Vision-language models (VLMs) may memorize undesirable information from training data, motivating growing interest in machine unlearning. In this work, we present the first systema…

HCRE: LLM-based Hierarchical Classification for Cross-Document Relation Extraction with a Prediction-then-Verification Strategy

Guoqi Ma, Liang Zhang, Hongyao Tu +6

Cross-document relation extraction (RE) aims to identify relations between the head and tail entities located in different documents. Existing approaches typically adopt the paradi…
