Adversarial Examples for -Nearest Neighbor Classifiers Based on Higher-Order Voronoi Diagrams
Chawin Sitawarin, Evgenios M. Kornaropoulos, Dawn Song +1
Adversarial examples are a widely studied phenomenon in machine learning models. While most of the attention has been focused on neural networks, other practical models also suffer…
Minimum-Norm Adversarial Examples on KNN and KNN-Based Models
Chawin Sitawarin, David Wagner
We study the robustness against adversarial examples of kNN classifiers and classifiers that combine kNN with neural networks. The main difficulty lies in the fact that finding an…
Defending Against Adversarial Examples with K-Nearest Neighbor
Chawin Sitawarin, David Wagner
Robustness is an increasingly important property of machine learning models as they become more and more prevalent. We propose a defense against adversarial examples based on a k-n…
Better the Devil you Know: An Analysis of Evasion Attacks using Out-of-Distribution Adversarial Examples
Vikash Sehwag, Arjun Nitin Bhagoji, Liwei Song +4
A large body of recent work has investigated the phenomenon of evasion attacks using adversarial examples for deep learning systems, where the addition of norm-bounded perturbation…
On the Robustness of Deep K-Nearest Neighbors
Chawin Sitawarin, David Wagner
Despite a large amount of attention on adversarial examples, very few works have demonstrated an effective defense against this threat. We examine Deep k-Nearest Neighbor (DkNN), a…
DARTS: Deceiving Autonomous Cars with Toxic Signs
Chawin Sitawarin, Arjun Nitin Bhagoji, Arsalan Mosenia +2
Sign recognition is an integral part of autonomous cars. Any misclassification of traffic signs can potentially lead to a multitude of disastrous consequences, ranging from a life-…
