The Dyna algorithm uses both real experience and model learning to facilitate simulation. However, the model used in Dyna is fairly limited, yet still has some desirable properties. Examination of a few different known models can help bring to light ways of improving the Dyna model. Combining ideas from what is learned about these models should allow to a greatly improved model for Reinforcement Learning simulation.application/pdfengReinforcement learning (Machine learning) -- Mathematical modelsComputer simulationArtificial intelligenceThesis
