Verification of Neural Networks' Global Robustness

no code implementations29 Feb 2024 Anan Kabaha, Dana Drachsler-Cohen

We evaluate VHAGaR on several datasets and classifiers and show that, given a three hour timeout, the average gap between the lower and upper bound on the minimal globally robust bound computed by VHAGaR is 1. 9, while the gap of an existing global robustness verifier is 154. 7.

Verification of Neural Networks Local Differential Classification Privacy

no code implementations31 Oct 2023 Roie Reshef, Anan Kabaha, Olga Seleznova, Dana Drachsler-Cohen

We propose Sphynx, an algorithm that computes an abstraction of all networks, with a high probability, from a small set of networks, and verifies LDCP directly on the abstract network.

Boosting Robustness Verification of Semantic Feature Neighborhoods

no code implementations12 Sep 2022 Anan Kabaha, Dana Drachsler-Cohen

Deep neural networks have been shown to be vulnerable to adversarial attacks that perturb inputs based on semantic features.

Learning Disjunctions of Predicates

no code implementations15 Jun 2017 Nader H. Bshouty, Dana Drachsler-Cohen, Martin Vechev, Eran Yahav

Our algorithm asks at most $|F| \cdot OPT(F_\vee)$ membership queries where $OPT(F_\vee)$ is the minimum worst case number of membership queries for learning $F_\vee$.
