What are Bayesian networks?
Bayesian networks are a type of Probabilistic Graphical Model that can be used to build models from data and expert opinion.
They can be used for a wide range of tasks including prediction, anomaly detection, diagnostics, automated insight, reasoning, time series prediction and decision making under uncertainty. Figure 1 below shows these capabilities in terms of the four major analytics disciplines, Descriptive analytics, Diagnostic analytics, Predictive analytics and Prescriptive analytics.
