When Stronger Triggers Backfire: A High-Dimensional Theory of Backdoor Attacks
Donald Flynn, Hadas Yaron Goldhirsh, Jonathan P. Keating +1
Backdoor poisoning attacks behave counter-intuitively in high dimensions: stronger training triggers can help the defender. We study regularised generalised linear models on Gaussi…

A Linear Approach to Data Poisoning
Donald Flynn, Diego Granziol
Backdoor and data-poisoning attacks can flip predictions with tiny training corruptions, yet a sharp theory linking poisoning strength, overparameterization, and regularization is…

Brownian Bees with Drift: Finding the Criticality
Donald Flynn
This dissertation examines the impact of a drift μ on Brownian Bees, which is a type of branching Brownian motion that retains only the N closest particles to the origin. The selec…
