Symmetry Defense Against XGBoost Adversarial Perturbation Attacks. (arXiv:2308.05575v1 [cs.LG])

We examine whether symmetry can be used to defend tree-based ensemble
classifiers such as gradient-boosting decision trees (GBDTs) against
adversarial perturbation attacks. The idea is based on a recent symmetry
defense for convolutional neural network classifiers (CNNs) that utilizes CNNs'
lack of invariance with respect to symmetries. CNNs lack invariance because
they can classify a symmetric sample, such as a horizontally flipped image,
differently from the original sample. CNNs' lack of invariance also means that
CNNs can classify symmetric adversarial …
