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

getBuildTransformation

public OraTransformation getBuildTransformation()

Returns the build transform that was set to this model.

Returns:

OraTransformation
