Efficient Availability Attacks against Supervised and Contrastive Learning Simultaneously

no code implementations6 Feb 2024 Yihan Wang, Yifan Zhu, Xiao-Shan Gao

Availability attacks can prevent the unauthorized use of private data and commercial datasets by generating imperceptible noise and making unlearnable examples before release.

Game-Theoretic Unlearnable Example Generator

1 code implementation31 Jan 2024 Shuang Liu, Yihan Wang, Xiao-Shan Gao

Unlearnable example attacks are data poisoning attacks aiming to degrade the clean test accuracy of deep learning by adding imperceptible perturbations to the training samples, which can be formulated as a bi-level optimization problem.

For naturalness, we constrain the adversarial example to be $\epsilon$-isometric to the original one by adopting the Gaussian curvature as a surrogate metric guaranteed by a theoretical analysis.

Achieve Optimal Adversarial Accuracy for Adversarial Deep Learning using Stackelberg Game

no code implementations17 Jul 2022 Xiao-Shan Gao, Shuang Liu, Lijia Yu

Game theory has been used to answer some of the basic questions about adversarial deep learning such as the existence of a classifier with optimal robustness and the existence of optimal adversarial samples for a given class of classifiers.

Adversarial Parameter Attack on Deep Neural Networks

no code implementations20 Mar 2022 Lijia Yu, Yihan Wang, Xiao-Shan Gao

In this paper, a new parameter perturbation attack on DNNs, called adversarial parameter attack, is proposed, in which small perturbations to the parameters of the DNN are made such that the accuracy of the attacked DNN does not decrease much, but its robustness becomes much lower.

Robust and Information-theoretically Safe Bias Classifier against Adversarial Attacks

no code implementations8 Nov 2021 Lijia Yu, Xiao-Shan Gao

The work is motivated by the fact that the bias part is a piecewise constant function with zero gradient and hence cannot be directly attacked by gradient-based methods to generate adversaries, such as FGSM.

Recently, Savar\'{e}-Toscani proved that the R\'{e}nyi entropy power of general probability densities solving the $p$-nonlinear heat equation in $\mathbb{R}^n$ is always a concave function of time, which extends Costa's concavity inequality for Shannon's entropy power to R\'{e}nyi entropies.
