ESE Seminar: “Safety and Robustness Guarantees with Learning in the Loop”

March 29 at 11:00 AM - 12:00 PM

In this talk, we present recent progress towards developing learning-based control strategies for the design of safe and robust autonomous systems. Our approach is to recognize that machine learning algorithms produce inherently uncertain estimates or predictions, and that this uncertainty must be explicitly quantified (e.g., using non-asymptotic guarantees of contemporary high-dimensional statistics) and accounted for (e.g., using robust control/optimization) when designing safety critical systems. We focus on the safety constrained optimal control of unknown systems, and show that by integrating modern tools from high-dimensional statistics and robust control, we can provide, to the best of our knowledge, the first end-to-end finite data robustness, safety, and performance guarantees for learning and control. We further show how this approach can be incorporated into an adaptive polynomial-time algorithm with non-asymptotic convergence rate (regret bound) guarantees. As a whole, these results provide a rigorous and contemporary perspective on safe reinforcement learning as applied to continuous control. We conclude with our vision for a general theory of safe learning and control, with the ultimate goal being the design of robust and high performing data-driven autonomous systems.

Nikolai Matni

Postdoctoral Scholar of Electrical Engineering and Computer Science, UC Berkeley

Nikolai is a postdoctoral scholar in EECS at UC Berkeley working with Benjamin Recht. He received the B.A.Sc. and M.A.Sc. in Electrical Engineering from the University of British Columbia, and the Ph.D. in Control and Dynamical Systems from the California Institute of Technology in June 2016 under the advisement of John C. Doyle. His research interests broadly encompass the use of learning, optimization, and control in the design and analysis of safety-critical data-driven cyber-physical systems. He was awarded the IEEE CDC 2013 Best Student Paper Award, and the IEEE ACC 2017 Best Student Paper Award (as co-advisor).
