oracle.dmt.jdm.base.OraTask
oracle.dmt.jdm.supervised.OraTestTask
OraTestTask
is an extension of the javax.datamining.supervised.TestTask
. It provides extension methods to retrieve the test input data details, description for test metrics and enabling/disabling of scoring cost matrix that is added to the input model.
