PRSA: Prompt Reverse Stealing Attacks against Large Language Models

no code implementations29 Feb 2024 Yong Yang, Xuhong Zhang, Yi Jiang, Xi Chen, Haoyu Wang, Shouling Ji, Zonghui Wang

In the mutation phase, we propose a prompt attention algorithm based on differential feedback to capture these critical features for effectively inferring the target prompts.

Let All be Whitened: Multi-teacher Distillation for Efficient Visual Retrieval

1 code implementation15 Dec 2023 Zhe Ma, Jianfeng Dong, Shouling Ji, Zhenguang Liu, Xuhong Zhang, Zonghui Wang, Sifeng He, Feng Qian, Xiaobo Zhang, Lei Yang

Instead of crafting a new method pursuing further improvement on accuracy, in this paper we propose a multi-teacher distillation framework Whiten-MTD, which is able to transfer knowledge from off-the-shelf pre-trained retrieval models to a lightweight student model for efficient visual retrieval.

Diff-ID: An Explainable Identity Difference Quantification Framework for DeepFake Detection

no code implementations30 Mar 2023 Chuer Yu, Xuhong Zhang, Yuxuan Duan, Senbo Yan, Zonghui Wang, Yang Xiang, Shouling Ji, Wenzhi Chen

We then visualize the identity loss between the test and the reference image from the image differences of the aligned pairs, and design a custom metric to quantify the identity loss.

Watch Out for the Confusing Faces: Detecting Face Swapping with the Probability Distribution of Face Identification Models

no code implementations23 Mar 2023 Yuxuan Duan, Xuhong Zhang, Chuer Yu, Zonghui Wang, Shouling Ji, Wenzhi Chen

We reflect this nature with the confusion of a face identification model and measure the confusion with the maximum value of the output probability distribution.
