Bruce Silver: “The ability to execute machine learning models is a standard feature of DMN.  From the start, the DMN spec said that in addition to the normal value expressions modeled in FEEL, decisions can execute machine learning models packaged using the Predictive Model Markup Language, or PMML. By providing a standard format for a wide range of machine learning model types, PMML enables interchange and interoperability across tools. In this post we’ll see how DMN can be used to make machine learning human-understandable” Link
