Reinforcement Planning: Planners as Policies

Introduction. State-of-the-art robotic systems [1, 2, 3] increasingly rely on search-based planning or optimal control methods to guide decision making. Similar observations can be made about computer game engines. Such methods are nearly always extremely crude approximations to the reality encountered by the robot: they consider a simplified model of the robot (as a point, or a “flying brick”)...

Locomotion Planning with 3D Character Animations by Combining Reinforcement Learning Based and Fuzzy Motion Planners

Motion and locomotion planning have a wide area of usage in different fields. Locomotion planning with premade character animations has been highly noticed in recent years. Reinforcement Learning presents promising ways to create motion planners using premade character animations. Although RL-based motion planners offer great ways to control character animations but they have some problems that...

RTP-Q: A Reinforcement Learning System with Time Constraints Exploration Planning for Accelerating the Learning Rate

Reinforcement learning is an efficient method for solving Markov Decision Processes that an agent improves its performance by using scalar reward values with higher capability of reactive and adaptive behaviors. Q-learning is a representative reinforcement learning method which is guaranteed to obtain an optimal policy but needs numerous trials to achieve it. k-Certainty Exploration Learning Sy...

Combining Reinforcement Learning with Symbolic Planning

One of the major difficulties in applying Q-learning to realworld domains is the sharp increase in the number of learning steps required to converge towards an optimal policy as the size of the state space is increased. In this paper we propose a method, PLANQ-learning, that couples a Q-learner with a STRIPS planner. The planner shapes the reward function, and thus guides the Q-learner quickly ...
