Who's Afraid of Adversarial Transferability?

no code implementations2 May 2021 Ziv Katzir, Yuval Elovici

By combining theoretical reasoning with a series of empirical results, we show that it is practically impossible to predict whether a given adversarial example is transferable to a specific target model in a black-box setting, hence questioning the validity of adversarial transferability as a real-life attack tool for adversaries that are sensitive to the cost of a failed attack.

Not All Datasets Are Born Equal: On Heterogeneous Data and Adversarial Examples

no code implementations7 Oct 2020 Yael Mathov, Eden Levy, Ziv Katzir, Asaf Shabtai, Yuval Elovici

We, however, argue that machine learning models trained on heterogeneous tabular data are as susceptible to adversarial manipulations as those trained on continuous or homogeneous data such as images.

Adversarial robustness via stochastic regularization of neural activation sensitivity

no code implementations23 Sep 2020 Gil Fidel, Ron Bitton, Ziv Katzir, Asaf Shabtai

Recent works have shown that the input domain of any machine learning classifier is bound to contain adversarial examples.

Why Blocking Targeted Adversarial Perturbations Impairs the Ability to Learn

no code implementations11 Jul 2019 Ziv Katzir, Yuval Elovici

We show that contrary to commonly held belief, the ability to bypass defensive distillation is not dependent on an attack's level of sophistication.

Detecting Adversarial Perturbations Through Spatial Behavior in Activation Spaces

no code implementations22 Nov 2018 Ziv Katzir, Yuval Elovici

We leverage those classifiers to produce a sequence of class labels for each nonperturbed input sample and estimate the a priori probability for a class label change between one activation space and another.
