Dynamic probabilistic networks are a compact representation of complex stochastic processes. In this paper we examine how to learn the structure of a DPN from data. ...
We extend structure scoring rules for standard probabilistic networks to the dynamic case, and show how to search for structure when some of the variables are hidden. ...
Acknowledgments We thank Jeff Forbes and Nikunj Oza for their help in getting the training data for the driving domain. ...
