Reinforcement Learning is Direct Adaptive Optimal Control

Reinforcement Learning is Direct Adaptive Optimal Control Stanford_cs229-notes12_Andrew_Ng Reinforcement Learning and 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… read more »

Hierarchical Policy Gradient Algorithms

Hierarchical Policy Gradient Algorithms Math Notation M : the overall task MDP. {M0, M1, M2 , M3 , . . . , Mn } : a finite set of subtask MDPs. Mi : subtask, models a subtask in the hierarchy. M0 : root task and solving it solves the entire MDP M. i : non-primitive subtask, paper uses… read more »
