Decision theory, reinforcement learning, and the brain.
Decision making is a core competence for animals and humans acting and surviving in environments they only partially comprehend, gaining rewards and punishments for their troubles. Decision-theoretic concepts permeate experiments and computational models in ethology, psychology, and neuroscience. Here, we review a well-known, coherent Bayesian approach to decision making, showing how it unifies...

متن کاملReinforcement Learning in the brain
The modern form of RL arose historically from two separate and parallel lines of research. The first axis is mainly associated with Richard Sutton, formerly an undergraduate psychology major, and his doctoral thesis advisor, Andrew Barto, a computer scientist. Interested in artificial intelligence and ag nt-based learning and inspired by the psychological literature on Pavlovian and instrumenta...
متن کاملReinforcement learning in the brain
A wealth of research focuses on the decision-making processes that animals and humans employ when selecting actions in the face of reward and punishment. Initially such work stemmed from psychological investigations of conditioned behavior, and explanations of these in terms of computational models. Increasingly, analysis at the computational level has drawn on ideas from reinforcement learning...
متن کاملReinforcement Learning: Theory and Practice
\Ve consider reinforcement learning methods for the solution of complex sequential optimization problems. In particular, the soundness of tV'lO methods proposed for the solution of partially obsenrable problems will be shown. The first method suggests a state-estimation scheme and requires mild a priori knowledge, \vhile the second method assumes that a significant amount of abstract knowl edg...
