WebProf. Ann E. Nicholson cofounded Bayesian Intelligence with Dr. Kevin Korb in 2007. She is a professor at Monash University who specializes in Bayesian network modelling. She is an expert in dynamic Bayesian networks (BNs), planning under uncertainty, user modelling, Bayesian inference methods and knowledge engineering BNs. 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).
