Abstract
Despite their performance, Artificial Neural Networks are not reliable enough
for most of industrial applications. They are sensitive to noises, rotations,
blurs and adversarial examples. There is a need to build defenses that protect
against a wide range of perturbations, covering the most traditional common
corruptions and adversarial examples. We propose a new data augmentation
strategy called M-TLAT and designed to address robustness in a broad sense. Our
approach combines the Mixup augmentation and a new adversarial training
algorithm called Targeted Labeling Adversarial Training (TLAT). The idea of
TLAT is to interpolate the target labels of adversarial examples with the
ground-truth labels. We show that M-TLAT can increase the robustness of image
classifiers towards nineteen common corruptions and five adversarial attacks,
without reducing the accuracy on clean samples.
