Method Detail

getSummary

public String getSummary()

Description copied from interface: Evaluator

Gets a short description of the Model.

evaluate

public Map<org.dmg.pmml.FieldName,?> evaluate(Map<org.dmg.pmml.FieldName,?> arguments)

Description copied from interface: Evaluator

Evaluates the model with the specified arguments.

Specified by:

evaluate in interface Evaluator

Overrides:

evaluate in class ModelEvaluator<JavaModel>

Parameters:

arguments - Map of input field values.

Returns:

Map of target field and output field values. A target field could be mapped to a complex value or a simple value. An output field is always mapped to a simple value. Complex values are represented as instances of Computable that return simple values. Simple values are represented using the Java equivalents of PMML data types (eg. String, Integer, Float, Double etc.). A missing value is represented by null.
