Whil e the asymptotic properties of these methods are well understood as the nu mber of data points goes to infinity or the noise level tends to zero\, ho w well their estimates in finite data regime evolve is relatively less stu died. This talk will mainly focus on our analysis of the robustness of the classical Ho-Kalman algorithm and how it translates to non-asymptotic est imation error bounds as a function of the number of data samples. In the s econd part of the talk\, I will describe a practical problem where a robot needs to learn safe behaviors from a limited number of demonstrations. We recast this problem as an inverse constraint learning problem\, similar t o inverse optimal control. Our experiments with several robotics problems show (local) optimality can be a very strong prior in learning from demons trations. I will conclude the talk with some open problems and directions for future research.\n \n Biography: Necmiye Ozay received her B.S. degree f rom Bogazici University\, Istanbul in 2004\, her M.S. degree from the Penn sylvania State University\, University Park in 2006 and her Ph.D. degree f rom Northeastern University\, Boston in 2010\, all in electrical engineeri ng. She was a postdoctoral scholar at the California Institute of Technolo gy\, Pasadena between 2010 and 2013. She joined the University of Michigan \, Ann Arbor in 2013\, where she is currently an associate professor of El ectrical Engineering and Computer Science. She is also a member of the Mic higan Robotics Institute. Dr. Ozay's research interests include hybrid dyn amical systems\, control\, optimization and formal methods with applicatio ns in cyber-physical systems\, system identification\, verification and va lidation\, autonomy and dynamic data analysis. Her papers received several awards. She received the 1938E Award and a Henry Russel Award from the Un iversity of Michigan for her contributions to teaching and research\, and five young investigator awards\, including NSF CAREER. She is also a recip ient of the 2021 Antonio Ruberti Young Researcher Prize from the IEEE Cont rol Systems Society for her fundamental contributions to the control and i dentification of hybrid and cyber-physical systems.\n  \n DTSTART:20220318T140000Z DTEND:20220318T150000Z LOCATION:CA\, ZOOM SUMMARY:Learning Models and Constraints with Limited Data URL:/cim/channels/event/learning-models-and-constraint s-limited-data-338443 END:VEVENT END:VCALENDAR
