We compare three different learning methods using a simulated robotic arm for the task of organizing different objects; the proposed methods are (i) deep reinforcement learning (DeepRL); (ii) interactive deep reinforcement learning using a previously trained artificial agent as an advisor (agent-IDeepRL); and (iii) interactive deep reinforcement learning using a human advisor (human-IDeepRL).

Explainable robotic systems: Understanding goal-driven actions in a reinforcement learning scenario

no code implementations • 24 Jun 2020 • Francisco Cruz, Richard Dazeley, Peter Vamplew, Ithan Moreira

As a way to explain the goal-driven robot's actions, we use the probability of success computed by three different proposed approaches: memory-based, learning-based, and introspection-based.
