A Dynamic Bayesian Network (DBN) is a Bayesian network (BN) which relates variables to each other over adjacent time steps. This is often called a Two-Timeslice BN (2TBN) because it says that at any point in time T, the value of a variable can be calculated from the internal regressors and the immediate … See more • Recursive Bayesian estimation • Probabilistic logic network • Generalized filtering See more • Murphy, Kevin (2002).
