How to train a Bayesian Network (BN) using expert knowledge?

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 In this article I will present the dbnlearn, my second package in R (it was published in CRAN on 2024-07-30).

WebOct 4, 2024 · 1. At the moment bnlearn can only be used for discrete/categorical modeling. There are possibilities to model your data though. You can for example discretize your variables with domain/experts knowledge or maybe a more data-driven threshold. Lets say, if you have a temperature, you can mark temperature < 0 as freezing, and >0 as normal.
