It's Simplex! Disaggregating Measures to Improve Certified Robustness

no code implementations20 Sep 2023 Andrew C. Cullen, Paul Montague, Shijie Liu, Sarah M. Erfani, Benjamin I. P. Rubinstein

Certified robustness circumvents the fragility of defences against adversarial attacks, by endowing model predictions with guarantees of class invariance for attacks up to a calculated size.

Failure-tolerant Distributed Learning for Anomaly Detection in Wireless Networks

no code implementations23 Mar 2023 Marc Katzef, Andrew C. Cullen, Tansu Alpcan, Christopher Leckie, Justin Kopacz

When such failures arise in wireless communications networks, important services that they use/provide (like anomaly detection) can be left inoperable and can result in a cascade of security problems.

Et Tu Certifications: Robustness Certificates Yield Better Adversarial Examples

no code implementations9 Feb 2023 Andrew C. Cullen, Shijie Liu, Paul Montague, Sarah M. Erfani, Benjamin I. P. Rubinstein

In guaranteeing the absence of adversarial examples in an instance's neighbourhood, certification mechanisms play an important role in demonstrating neural net robustness.

Double Bubble, Toil and Trouble: Enhancing Certified Robustness through Transitivity

1 code implementation12 Oct 2022 Andrew C. Cullen, Paul Montague, Shijie Liu, Sarah M. Erfani, Benjamin I. P. Rubinstein

In response to subtle adversarial examples flipping classifications of neural network models, recent research has promoted certified robustness as a solution.
