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.


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.


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.
