There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

Cybersecurity Lecture Series by IISPThe Cybersecurity Lecture Series at Georgia Tech is a free, one-hour lecture from a thought leader who is advancing the field of information security and privacy. Invited speakers include executives and researchers from Fortune 500 companies, federal intelligence agencies, start-ups, and incubators, as well as Georgia Tech faculty and students presenting their research. Lectures are open to all -- students, faculty, industry, government, or simply the curious.
While Artificial Intelligence (AI) has tremendous potential as a defense against real-world cybersecurity threats, understanding the capabilities and robustness of AI remains a fundamental challenge, especially in adversarial environments. In this talk, I address two interrelated problems that are essential to the successful deployment of AI in security settings. (1) Discovering real-world vulnerabilities of deep neural networks and countermeasures to mitigate threats. I will present ShapeShifter, the first targeted physical adversarial attack that fools state-of-the-art object detectors, and SHIELD, a real-time defense that removes adversarial noise by stochastic data compression. (2) Developing theoretically-principled methods for choosing machine models to defend against unknown future attacks. I will introduce a novel game theory concept called “diversified strategy” to help make the optimal decision with limited risk. Finally, I will share my vision on making AI more robust under different threat models, and research directions on deploying AI in security-critical and high-stakes problems.
Shang-Tse Chen is a Ph.D. Candidate in Computer Science at Georgia Tech. He works in the intersection of applied and theoretical machine learning. His research focuses on designing robust machine learning algorithms for security-critical applications. He has worked closely with industry and government partners. His research has led to patent-pending cyber threat detection technology with Symantec, open-sourced adversarial attack and defense tools with Intel, deployed fire risk prediction system with the Atlanta Fire Rescue Department. He is a recipient of the KDD Best Student Paper Runner-up Award (2016) and the IBM Ph.D. Fellowship (2018).
