Beyond Superficial Unlearning: Sharpness-Aware Robust Erasure of Hallucinations in Multimodal LLMs

Xianya Fang, Feiyang Ren, Xiang Chen +4

Multimodal LLMs are powerful but prone to object hallucinations, which describe non-existent entities and harm reliability. While recent unlearning methods attempt to mitigate this…

Reflect then Learn: Active Prompting for Information Extraction Guided by Introspective Confusion

Dong Zhao, Yadong Wang, Xiang Chen +6

Large Language Models (LLMs) show remarkable potential for few-shot information extraction (IE), yet their performance is highly sensitive to the choice of in-context examples. Con…

SafeThinker: Reasoning about Risk to Deepen Safety Beyond Shallow Alignment

Xianya Fang, Xianying Luo, Yadong Wang +8

Despite the intrinsic risk-awareness of Large Language Models (LLMs), current defenses often result in shallow safety alignment, rendering models vulnerable to disguised attacks (e…

Retrieval-augmented Prompt Learning for Pre-trained Foundation Models

Xiang Chen, Yixin Ou, Quan Feng +8

The pre-trained foundation models (PFMs) have become essential for facilitating large-scale multimodal learning. Researchers have effectively employed the ``pre-train, prompt, and…

Tailored Teaching with Balanced Difficulty: Elevating Reasoning in Multimodal Chain-of-Thought via Prompt Curriculum

Xinglong Yang, Quan Feng, Zhongying Pan +7

The effectiveness of Multimodal Chain-of-Thought (MCoT) prompting is often limited by the use of randomly or manually selected examples. These examples fail to account for both mod…

MultiMedEdit: A Scenario-Aware Benchmark for Evaluating Knowledge Editing in Medical VQA

Shengtao Wen, Haodong Chen, Yadong Wang +6

Knowledge editing (KE) provides a scalable approach for updating factual knowledge in large language models without full retraining. While previous studies have demonstrated effect…
