PFA scoring engines are formatted as either JSON or YAML. This node reads such files and outputs the PFA as a KNIME port, allowing it to be used in conjunction with a PFA Predictor node.
PFA is expressed as a JSON or YAML document. It has control structures, e.g. conditionals, loops and user-defined functions. For more information please visit the DMG PFA website. Supported primitive types are: boolean, int, long, float, double, string. Supported complex types are: Arrays, Records, Maps, Union (Union types are used for nullable types in PFA. Other use cases are currently not supported).
