Title: Towards Resilient Machine Learning in Adversarial Environments

Abstract:

Machine learning is increasingly being used for automated decisions in applications such as health care, finance, and cyber security. In these critical environments, attackers have strong incentives to manipulate the results and models generated by machine learning algorithms. The area of adversarial machine learning studies the effect of adversarial attacks against machine learning models and aims to design robust defense algorithms. In this talk I will first describe several applications of machine learning for advanced threat detection. Then, I will present recent work on poisoning attacks at training time and evasion attacks at testing time against different classification and regression algorithms. I will discuss the impact of the attacks on several real-world applications from cyber security and self-driving cars. I will also mention a number of  challenges in securing machine learning in critical adversarial environments.
