CS Colloquium: Scott Niekum (UT Austin) - Scaling Probabilistically Safe Learning to Robotics

Speaker: Scott Niekum, The University of Texas at Austin

Talk Title: Scaling Probabilistically Safe Learning to Robotics

Series: Computer Science Colloquium

Abstract: Before learning robots can be deployed in the real world, it is critical that probabilistic guarantees can be made about the safety and performance of such systems. In recent years, safe reinforcement learning algorithms have enjoyed success in application areas with high-quality models and plentiful data, but robotics remains a challenging domain for scaling up such approaches. Furthermore, very little work has been done on the even more difficult problem of safe imitation learning, in which the demonstrator's reward function is not known. This talk focuses on new developments in three key areas for scaling safe learning to robotics: (1) a theory of safe imitation learning; (2) scalable reward inference in the absence of models; (3) efficient off-policy policy evaluation. The proposed algorithms offer a blend of safety and practicality, making a significant step towards safe robot learning with modest amounts of real-world data.

This lecture satisfies requirements for CSCI 591: Research Colloquium.
