Class OraModel

java.lang.Object
oracle.dmt.jdm.OraDMObject
oracle.dmt.jdm.OraMiningObject
oracle.dmt.jdm.base.OraModel

All Implemented Interfaces:

javax.datamining.MiningObject, javax.datamining.base.Model, oracle.dmt.jdm.OraPLSQLConstants

Direct Known Subclasses:

OraFeatureExtractionModel, oracle.dmt.jdm.supervised.OraSupervisedModel

public abstract class OraModel

extends oracle.dmt.jdm.OraMiningObject

implements javax.datamining.base.Model

OraModel is an extension of JDM standard javax.datamining.base.Model interface. It provides an extension method getModelTransformations to retrieve the transformations that are either automatically done by the DME or user explicitely embedded in the model build process. It also defines 11.1 deprectaed 10.2 methods setBuildTransformation and getBuildTransformation, which are used to support reverse transformation of the model details in 10.2. As 11.1 supports automated/embedded transformations with the mining model, no need for these methods.

Method Summary

OraTransformation	getBuildTransformation() Returns the build transform that was set to this model.
OraExpressionTransform	getModelTransformations() Returns automated or embedded model transformations.
void	setBuildTransformation(OraTransformation buildTransform) For viewing more descriptive model by reverse transforming this method is used to set the external transformation done at the build time.

Method Detail

setBuildTransformation

public void setBuildTransformation(OraTransformation buildTransform)
                            throws javax.datamining.JDMException

For viewing more descriptive model by reverse transforming this method is used to set the external transformation done at the build time. This method accepts only binning and normalization type transformations. For example, in SVM, k-Means, NMF algorithms build data normalization must be done to get all the attributes to the same scale. In this case model shows the normalized values, which could cause problems in viewing and interpriting the model. This method addresses this issue by providing a way to set the transformation done on build data to the model to do the reverse transformation before displaying the model details. Note: This transformation details are not stored with the model. Applications have to set this whenever reverse-transformations to be done.

Parameters:

buildTransform -

Throws:

javax.datamining.JDMException
