Microsoft Researchers Propose Neural Graphical Models (NGMs): A New Type of Probabilistic Graphical Models (PGM) that Learns to Represent the Probability Function Over the Domain Using a Deep Neural Network

Marktechpost

Many graphical models are designed to work exclusively with continuous or categorical variables, limiting their applicability to data that spans different types. Moreover, specific restrictions, such as continuous variables not being allowed as parents of categorical variables in directed acyclic graphs (DAGs), can hinder their flexibility.
