Instance-based reinforcement learning for robot path finding in continuous space

摘要

This paper presents two methods of shaping autonomous mobile robots within a framework of instance-based reinforcement learning. The first one is instance-based classifier generator, which is used to learn primitive behaviors. The second one is reinforcement learning based on behavior sequence memory, which is used to learn optimal path and to distinguish hidden states. Learning capability of the proposed methods is confirmed through a path-finding task of a mobile robot in continuous space. Simulation results demonstrate that the robot can acquire behaviors such as light-seeking, collision-avoidance and wall-following, and it can also find the optimal paths in the alternately changing environments.
