Autonomous Learning Laboratory

College of Information and Computer Sciences
University of Massachusetts Amherst

The Autonomous Learning Laboratory (ALL) conducts foundational artificial intelligence (AI) research, with emphases on AI safety and reinforcement learning (RL), and particularly the intersection of these two areas.

The long-term goals of the laboratory are to develop more capable artificial agents, ensure that systems that use artificial intelligence methods are safe and well-behaved, improve our understanding of biological learning and its neural basis, and to forge stronger links between studies of learning by computer scientists, engineers, neuroscientists, and psychologists.
