# Reward Prediction Error **Domain:** Neuroscience / Reinforcement Learning **Doc Type:** Concept **Maturity:** Developed **Related:** [[Wolfram Schultz]], [[Peter Dayan]], [[P. Read Montague]], [[Temporal-Difference Learning]], [[Schedule and Loop]] ## Definition Reward prediction error is the difference between expected and received reward used to update future predictions and action values. ## Schedule–Loop Context It is the mathematical hinge of the schedule-loop merger: an organism's response to reinforcement becomes an error signal inside a learning controller. ## Backlinks - [[Schedule and Loop]] - [[articles/Schedule and Loop|Schedule and Loop]] - [[Russia and Prussia Kybernetiks]]
