Method Detail

prepare

public Object prepare(FieldName name,
             Object value)

Description copied from interface: Evaluator

Prepares the input value for a field. First, the value is converted from the user-supplied representation to internal representation. Later on, the value is subjected to missing value treatment, invalid value treatment and outlier treatment.

Specified by:

prepare in interface Evaluator

Parameters:

name - The name of the field

See Also:

Consumer.getDataField(FieldName), Consumer.getMiningField(FieldName)

evaluate

public Map<FieldName,?> evaluate(Map<FieldName,?> parameters)

Specified by:

evaluate in interface Evaluator

Parameters:

parameters - Map of active field values.

Returns:

Map of predicted field and output field values. Simple values are represented using the Java equivalents of PMML data types (eg. String, Integer, Float, Double etc.). Complex values are represented as instances of Computable that return simple values.
