Reinforcement learning encompasses theoretical frameworks and computational techniques for optimal decision-making, developed over the past quarter-century within machine learning and operations research, while also gaining significance in psychology and neuroscience. These approaches provide practical approximations for complex optimal-control challenges that exceed the capabilities of traditional methods like dynamic programming. Notable applications include autonomous helicopter flight, elevator control systems, backgammon gameplay, and scheduling with limited resources.
At the University of Alberta, researchers focus on advancing reinforcement learning by overcoming current constraints to broaden its applicability. They aim to evolve these methods into models of intelligence capable of matching human cognitive performance. This work involves mathematical innovation, computational testing, robotic implementations, game-based applications, and the creation of computational models that simulate natural learning mechanisms.
