WebMar 2, 2024 · A DBN is a bayesian network that represents a temporal probability model, each time slice can have any number of state variables and evidence variables. Every hidden markov model (HMM) can be represented as a DBN and every DBN can be translated into an HMM. A DBN is smaller in size compared to a HMM and inference is … WebBayesian networks are a type of Probabilistic Graphical Model that can be used to build models from data and/or expert opinion. They can be used for a wide range of tasks including diagnostics, reasoning, causal modeling, decision making under uncertainty, anomaly detection, automated insight and prediction.
