Proceedings Article
Reinforcement learning from demonstration through shaping
TL;DR: This paper investigates the intersection of reinforcement learning and expert demonstrations, leveraging the theoretical guarantees provided by reinforcement learning, and using expert demonstrations to speed up this learning by biasing exploration through a process called reward shaping.
Proceedings ArticleDOI
Learning from Demonstration for Shaping through Inverse Reinforcement Learning
TL;DR: This paper introduces a novel approach to improve model-free reinforcement learning agents' performance with a three step approach, which outperforms the state-of-the-art in cumulative reward, learning rate and asymptotic performance.
Proceedings ArticleDOI
Policy Transfer using Reward Shaping
TL;DR: This work advances the state-of-the-art by using a reward shaping approach to policy transfer, enabling transfer irrespective of the learning algorithm used in the source task.
Journal ArticleDOI
Distributed learning and multi-objectivity in traffic light control
TL;DR: A study of DCEE and RL techniques in a complex simulator, illustrating the particular advantages of each, comparing them against standard isolated traffic actuated signals and evaluating several alternative reward signals in the best performing approach.
Proceedings ArticleDOI
Multi-objectivization of reinforcement learning problems by reward shaping
TL;DR: It is shown that adding several correlated signals can help to solve the basic single objective problem faster and better, and it is proved that the total ordering of solutions, and by consequence the optimality of solutions is preserved.
