CS Colloquium Speaker Speaker: Benjamin Eysenbach, Carnegie Mellon University Date: Tuesday, March 21 Time: 12:30pm EST Location: CS 105 Host: Karthik Narasim Event page: https://www.cs.princeton.edu/events/26345 Title: Self-Supervised Reinforcement Learning Abstract: Reinforcement learning (RL) promises to harness the power of machine learning to solve sequential decision making problems, with the potential to enable applications ranging from robotics to chemistry. However, what makes the RL paradigm broadly applicable is also what makes it challenging: only limited feedback is provided for learning to select good actions. In this talk, I will discuss how we have made headway of this challenge by designing a class of self-supervised RL methods, ones that can learn skills for acting using unsupervised (reward-free) experience. These skill learning methods are practically-appealing and have since sparked a vibrant area of research. I will also share how we have answered some open theoretical questions in this area. Bio: Benjamin Eysenbach a final-year PhD student at Carnegie Mellon University. His research has developed machine learning algorithms for sequential decision making. His algorithms not only achieve a high degree of performance, but also carry theoretical guarantees, are typically simpler than prior methods, and draw connections between many areas of ML and CS. Ben is the recipient of the NSF and Hertz graduate fellowships. Prior to the PhD, he was a resident at Google Research and studied math as an undergraduate at MIT.
