Method Detail

getModel

public M getModel()

getSummary

public String getSummary()

Description copied from interface: Consumer

Returns a short description of the underlying Model

Specified by:

getSummary in interface Consumer

getActiveFields

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

Description copied from interface: Consumer

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

Specified by:

getActiveFields in interface Consumer

getGroupFields

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

Description copied from interface: Consumer

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

Specified by:

getGroupFields in interface Consumer

getOrderFields

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

Description copied from interface: Consumer

Gets the order fields of a Model from its MiningSchema.

Specified by:

getOrderFields in interface Consumer

getTargetFields

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

Description copied from interface: Consumer

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

Specified by:

getTargetFields in interface Consumer

getTargetField

public org.dmg.pmml.FieldName getTargetField()

Description copied from interface: Consumer

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, 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 "true" or "phantom". They can be distinguished from one another by looking up the definitoon.

 Consumer consumer = ...;

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

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

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

Specified by:

getTargetField in interface Consumer

Returns:

The sole target field.
