Accepted for presentation at the 9th European Workshop on Reinforcement Learning and to be published in the Workshop Proceedings, 2011. Abstract: In this paper we investigate using multiple mappings for
transfer learning in reinforcement learning tasks. We propose two dif-
ferent transfer learning algorithms that are able to manipulate multiple
inter-task mappings for both model-learning and model-free reinforce-
ment learning algorithms. Both algorithms incorporate mechanisms to
select the appropriate mappings, helping to avoid the phenomenon of
negative transfer. The proposed algorithms are evaluated in the Moun-
tain Car and Keepaway domains. Experimental results show that the use
of multiple inter-task mappings can significantly boost the performance
of transfer learning methodologies, relative to using a single mapping or
learning without transfer.
