Method Detail

getSummary

String getSummary()

Gets a short description of the Model.

getMiningFunction

org.dmg.pmml.MiningFunctionType getMiningFunction()

Gets the type of the Model.

getDataField

org.dmg.pmml.DataField getDataField(org.dmg.pmml.FieldName name)

Gets the definition of a field from the DataDictionary.

Parameters:

name - The name of the field. The name of the default target field is null.

getActiveFields

List<org.dmg.pmml.FieldName> getActiveFields()

Gets the independent (ie. input) fields of a Model from its MiningSchema.

getGroupFields

List<org.dmg.pmml.FieldName> getGroupFields()

Gets the group fields of a Model from its MiningSchema. A model should have no more than 1 group field.

getOrderFields

List<org.dmg.pmml.FieldName> getOrderFields()

Gets the order fields of a Model from its MiningSchema. This field set is relevant only for association rules model type.

getTargetFields

List<org.dmg.pmml.FieldName> getTargetFields()

Gets the dependent (ie. target in supervised training) fields of a Model from its MiningSchema.

getTargetField

org.dmg.pmml.FieldName getTargetField()

Convenience method for retrieving the sole target field. A supervised model should, but is not required to, define a target field. An unsupervised model, by definition, does not define a target field. If the collection of target fields is empty, then the model consumer should assume that the model defines a default target field, which is represented by null. The default target field could be either "real" or "phantom". They can be distinguished from one another by looking up the definition of the field from the DataDictionary.

 Consumer consumer = ...;

 List<FieldName> targetFields = consumer.getTargetFields();
 if(targetFields.isEmpty()){
   FieldName targetField = consumer.getTargetField();

   DataField dataField = consumer.getDataField(targetField);
   if(dataField != null){
     // A "real" default target field
   } else

   {
     // A "phantom" default target field
   }
 }
 

Returns:

The sole target field.

Throws:

InvalidFeatureException - If the number of target fields is greater than one.

getMiningField

org.dmg.pmml.MiningField getMiningField(org.dmg.pmml.FieldName name)
