Adversarial Robustness in Next-Generation AI: Defense Mechanisms for Image and Text Models
Download PDFAbstract
This chapter provides a comprehensive exploration of adversarial robustness in next-generation artificial intelligence (AI) systems, with a specific focus on defense mechanisms for image and text models. As AI models, particularly deep neural networks, become increasingly integrated into critical applications, their vulnerability to adversarial attacks presents a significant security challenge. Adversarial examples, which are inputs intentionally perturbed to cause model misclassification, can have severe consequences in domains such as autonomous driving, medical diagnostics, and natural language understanding. This chapter systematically reviews the landscape of adversarial attacks, from foundational gradient-based methods to sophisticated transfer and query-based attacks. We then delve into a detailed analysis of state-of-the-art defense strategies, including adversarial training, defensive distillation, and certified robustness techniques. To provide a practical understanding of these concepts, we present a case study involving the implementation and evaluation of adversarial attacks and defenses on the CIFAR-10 image dataset. The results of our simulations demonstrate the effectiveness of adversarial training in enhancing model robustness against common attacks like the Fast Gradient Sign Method (FGSM) and Projected Gradient Descent (PGD). Finally, we discuss the open challenges and future research directions in the pursuit of building truly robust and trustworthy AI systems.
