About Me

Samuel Barrett I am interested in artificial intelligence, machine learning, and robotics. In particular, I enjoy working on reinforcement learning and sequential decision making problems, especially in the intersection of research and applications.

Work

I am currently a senior research scientist at Sony AI working on artificial intelligence and games. I previously worked at Cogitai, Inc., a startup working on continual learning, before Sony AI acquired Cogitai in 2019. Prior to that, I worked at Amazon Robotics to use AI to improve the performance of the robotics system that runs in some of Amazon's warehouses. I defended my Ph.D. thesis at the University of Texas at Austin in October, 2014. My dissertation examined the problem of ad hoc teamwork, cooperating with unknown teammates. Specifically, I looked into how robots and other agents could reuse knowledge learned about previous teammates in order to quickly adapt to new teammates. My advisor was Peter Stone, and I was a member of the Learning Agents Research Group (LARG). While at UT, I also helped the UT Austin Villa team win the 2012 international RoboCup competition in the standard platform league (SPL). Before joining UT, I obtained my B.S. in Computer Science from Stevens Institute of Technology in May 2008.

Research

My research interests are in artificial intelligence, machine learning, and robotics. I am primarily interested in reinforcement learning and how to build knowledge from experience in sequential decision making tasks. My dissertation focused on ad hoc teams: how agents should learn to deal with unknown teammates to accomplish shared goals. My goal was to create agents that can cooperate with any other teammates in a new environment and can still learn to perform effectively. I used techniques in the areas of transfer learning and reinforcement learning to allow agents to quickly learn and adapt to new teammates. You can find out more about my research through my publications.
