TL;DR#
Adversarial training enhances machine learning models’ resilience against malicious attacks. However, understanding why and when it works remains limited; existing analyses often oversimplify data or restrict model complexity. This lack of theoretical understanding hinders the development of truly robust and reliable algorithms.
This research addresses this gap by rigorously analyzing adversarial training for two-layer neural networks. They demonstrate how generalization bounds can be controlled via early stopping, particularly for sufficiently wide networks. Furthermore, they introduce Moreau’s envelope smoothing to improve the generalization bounds even further. This work provides valuable theoretical insights and practical techniques to advance robust machine learning.
