Combining Memory and Landmarks with Predictive State Representations

  title={Combining Memory and Landmarks with Predictive State Representations},
  author={Michael R. James and Britton Wolfe and Satinder P. Singh},
It has recently been proposed that it is advantageous to have models of dynamical systems be based solely on observable quantities. Predictive state representations (PSRs) are a type of model that uses predictions about future observations to capture the state of a dynamical system. However, PSRs do not use memory of past observations. We propose a model called memory-PSRs that uses both memories of the past, and predictions of the future. We show that the use of memories provides a number of… CONTINUE READING
