Title: Safety and robustness guarantees with learning in the loop

Speaker: Prof. Dr. Nikolai Matni, University of Pennsylvania

 

Abstract:
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 and optimization) when designing safety critical systems. In the first half of the talk, we consider the optimal control of an unknown dynamical system, and show that by integrating modern tools from high-dimensional statistics and robust control, we can provide end-to-end finite data robustness, safety, and performance guarantees for learning and control. In the second half of the talk, motivated by vision based control of autonomous vehicles, we consider the complementary problem of controlling a known dynamical system for which partial state information, such as vehicle position, can only be extracted from high-dimensional data, such as an image. Our approach is to learn a perception map from high-dimensional data to partial-state observation, as well as its corresponding error profile, and then design a robust controller. We show that jointly learning the perception map and error profile can be cast as a robust regression problem, and that this allows us to treat the perception map as a noisy position sensor, which can then be integrated into a novel robust control synthesis procedure that has favorable safety and generalization properties. We conclude with our thoughts on future challenges and opportunities in the broad area of safe learning and control.
