Counting Circuits: Mechanistic Interpretability of Visual Reasoning in Large Vision-Language Models

Liwei Che, Zhiyu Xue, Yihao Quan +7

Counting serves as a simple but powerful test of a Large Vision-Language Model's (LVLM's) reasoning; it forces the model to identify each individual object and then add them all up…

Deactivating Refusal Triggers: Understanding and Mitigating Overrefusal in Safety Alignment

Zhiyu Xue, Zimo Qi, Guangliang Liu +2

Safety alignment aims to ensure that large language models (LLMs) refuse harmful requests by post-training on harmful queries paired with refusal answers. Although safety alignment…

Enhancing the Safety of Medical Vision-Language Models by Synthetic Demonstrations

Zhiyu Xue, Reza Abbasi-Asl, Ramtin Pedarsani

Generative medical vision-language models~(Med-VLMs) are primarily designed to generate complex textual information~(e.g., diagnostic reports) from multimodal inputs including visi…

Conflict-Aware Adversarial Training

Zhiyu Xue, Haohan Wang, Yao Qin +1

Adversarial training is the most effective method to obtain adversarial robustness for deep neural networks by directly involving adversarial samples in the training procedure. To…

Communication-Efficient and Tensorized Federated Fine-Tuning of Large Language Models

Sajjad Ghiasvand, Yifan Yang, Zhiyu Xue +3

Parameter-efficient fine-tuning (PEFT) methods typically assume that Large Language Models (LLMs) are trained on data from a single device or client. However, real-world scenarios…

Initialization Matters for Adversarial Transfer Learning

Andong Hua, Jindong Gu, Zhiyu Xue +3

With the prevalence of the Pretraining-Finetuning paradigm in transfer learning, the robustness of downstream tasks has become a critical concern. In this work, we delve into adver…
