Duanyi Yao, Changyue Li, Zhicong Huang +2
Vision-Language Models (VLMs) are increasingly deployed in consumer applications where users seek recommendations about products, dining, and services. We introduce Hidden Ads, a n…
Noise as a Probe: Membership Inference Attacks on Diffusion Models Leveraging Initial Noise
Puwei Lian, Yujun Cai, Songze Li +1
Diffusion models have achieved remarkable progress in image generation, but their increasing deployment raises serious concerns about privacy and copyright. In particular, fine-tun…
Bi-Erasing: A Bidirectional Framework for Concept Removal in Diffusion Models
Hao Chen, Yiwei Wang, Songze Li
Concept erasure, which fine-tunes diffusion models to remove undesired or harmful visual concepts, has become a mainstream approach to mitigating unsafe or illegal image generation…
Visual CoT Makes VLMs Smarter but More Fragile
Chunxue Xu, Yiwei Wang, Yujun Cai +2
Chain-of-Thought (CoT) techniques have significantly enhanced reasoning in Vision-Language Models (VLMs). Extending this paradigm, Visual CoT integrates explicit visual edits, such…
Enhancing Membership Inference Attacks on Diffusion Models from a Frequency-Domain Perspective
Puwei Lian, Yujun Cai, Songze Li +1
Diffusion models have achieved tremendous success in image generation, but they also raise significant concerns regarding privacy and copyright issues. Membership Inference Attacks…
How does Watermarking Affect Visual Language Models in Document Understanding?
Chunxue Xu, Yiwei Wang, Bryan Hooi +2
Visual Language Models (VLMs) have become foundational models for document understanding tasks, widely used in the processing of complex multimodal documents across domains such as…
