Reinforcement Learning and Approximate Dynamic Programming (RLADP)—Foundations, Common Reinforcement learning (RL) is an area of machine learning inspired by behaviourist psychology, concerned with how software agents ought to take actions in an Machine learning is a field of computer science that gives computer systems the ability to. Reinforcement Learning and Dynamic Programming Using Function Approximators provides a comprehensive and unparalleled exploration of the field of RL and DP. We can now place component ideas, such as temporal-difference learning, dynamic programming, and function approximation, within a coherent perspective with respect to the overall problem. The seven articles of this special issue are representative of the excellent reinforcement learning research ongoing today. In: IEEE Symposium on Adaptive Dynamic Programming and Reinforcement Learning (ADPRL). planning and reinforcement learning 2. Reinforcement learning (RL) and adaptive dynamic programming (ADP) has been one of the most critical research fields in science and engineering for modern complex systems.
