Membership Inference Attacks Against Text-to-image Generation Models

no code implementations3 Oct 2022 Yixin Wu, Ning Yu, Zheng Li, Michael Backes, Yang Zhang

The empirical results show that all of the proposed attacks can achieve significant performance, in some cases even close to an accuracy of 1, and thus the corresponding risk is much more severe than that shown by existing membership inference attacks.

Revisiting the Characteristics of Stochastic Gradient Noise and Dynamics

no code implementations20 Sep 2021 Yixin Wu, Rui Luo, Chen Zhang, Jun Wang, Yaodong Yang

In this paper, we characterize the noise of stochastic gradients and analyze the noise-induced dynamics during training deep neural networks by gradient-based optimizers.

Node-Level Membership Inference Attacks Against Graph Neural Networks

no code implementations10 Feb 2021 Xinlei He, Rui Wen, Yixin Wu, Michael Backes, Yun Shen, Yang Zhang

To fully utilize the information contained in graph data, a new family of machine learning (ML) models, namely graph neural networks (GNNs), has been introduced.
