Reinforcement Learning is Direct Adaptive Optimal Control
March 1, 2019
Reinforcement Learning is Direct Adaptive Optimal Control How should Reinforcement learning be viewed from a control systems perspective? Control problems can be divided into two classes: regulation and tracking problems, in which the objective is to follow a reference trajectory. optimal control problems, which the objective is to extremize a functional of the controlled system’s… read more »
