WebJul 1, 2024 · 1. Introduction. Bayesian Networks (BNs) have received increasing attention during the last two decades [1, 2] for their particular ability to be applied to challenging issues and aid those making decisions to reason about cause and outcome under conditions of uncertainty [[3], [4], [5]].In 2016, the journal Machine Learning ran a special issue on … WebCTBNs is easier than for traditional BNs or dynamic Bayesian networks (DBNs). We develop an inference algorithm for CTBNs which is a variant of expectation propaga-tion and leverages domain structure and the explicit model of time for computational vi. advantage. We also show how to use CTBNs to model a rich class of distributions
