The Dyna class of reinforcement learning architectures enables the creation of integrated learning, planning and reacting systems. A class of strategies designed to enhance the learning and planning power of Dyna systems by increasing their computational efficiency is examined. The benefit of using these strategies is demonstrated on some simple abstract learning tasks. It is proposed that the backups to be performed in Dyna be prioritized in order to improve its efficiency. It is demonstrated with simple tasks that use some specific prioritizing schemes can lead to significant reductions in computational effort and corresponding improvements in learning performance
