Regularized Ensembles and Transferability in Adversarial Learning
Yifan Chen, Yevgeniy Vorobeychik
Despite the considerable success of convolutional neural networks in a broad array of domains, recent research has shown these to be vulnerable to small adversarial perturbations,…
Removing Malicious Nodes from Networks
Sixie Yu, Yevgeniy Vorobeychik
A fundamental challenge in networked systems is detection and removal of suspected malicious nodes. In reality, detection is always imperfect, and the decision about which potentia…
Plan Interdiction Games
Yevgeniy Vorobeychik, Michael Pritchard
We propose a framework for cyber risk assessment and mitigation which models attackers as formal planners and defenders as interdicting such plans. We illustrate the value of plan…
Attacking Similarity-Based Link Prediction in Social Networks
Kai Zhou, Tomasz P. Michalak, Talal Rahwan +2
Link prediction is one of the fundamental problems in computational social science. A particularly common means to predict existence of unobserved links is via structural similarit…
Defending Elections Against Malicious Spread of Misinformation
Bryan Wilder, Yevgeniy Vorobeychik
The integrity of democratic elections depends on voters' access to accurate information. However, modern media environments, which are dominated by social media, provide malicious…
Attack Tolerance of Link Prediction Algorithms: How to Hide Your Relations in a Social Network
Marcin Waniek, Kai Zhou, Yevgeniy Vorobeychik +3
Link prediction is one of the fundamental research problems in network analysis. Intuitively, it involves identifying the edges that are most likely to be added to a given network,…
