Fast Adversarial Training
Fast adversarial training (FAT) aims to improve the robustness of machine learning models against adversarial attacks while significantly reducing the computational cost of traditional adversarial training methods. Current research focuses on mitigating issues like catastrophic overfitting, which causes a sudden drop in model robustness, often employing techniques like adaptive loss functions, novel initialization strategies, and bi-level optimization approaches within various model architectures, including convolutional neural networks and vision transformers. These advancements are crucial for deploying robust machine learning models in safety-critical applications, particularly in areas like natural language processing and computer vision, where adversarial attacks pose significant risks.
