ACR-Tree: Constructing R-Trees Using Deep Reinforcement Learning

WebHowever, solving the POMDP with reinforcement learning (RL) [2] often requires storing a large number of observations. Furthermore, for continuous action spaces, the system is computationally inefficient. This paper addresses these problems by proposing to model the problem as an MDP and learn a policy with RL using hierarchical options (HOMDP). Webhierarchical structure that is no larger than both the reduced model of the MDP and the regression tree for the goal in that MDP, and then using that structure to solve for a policy. 1 Introduction Our goal is to solve a large class of very large Markov de-cision processes (MDPs), necessarily sacriﬁcing optimality for feasibility. shiny shorts boys
