Direct Known Subclasses:

OraClassificationTestMetricsTask

public class OraClassificationTestTask

extends OraTestTask

implements javax.datamining.supervised.classification.ClassificationTestTask

A ClassificationTestTask is a mining task used for testing a classificationmodel to measure the goodness of the model. The results of executing a classification test task include the accuracy of the model and a confusion matrix that is the statistics of the predictions made during the test.

Method Detail

setTableName

public void setTableName(javax.datamining.supervised.classification.ClassificationTestMetricOption testMetric,
                         java.lang.String tableName)

Sets the table name to be used for persisting the associated test metric option related details. For example, to persist confusion matrix in a table "CHURN_CONFUSION_MATRIX" call setTableName(ClassificationTestMetricOption.confusionMatrix, " CHURN_CONFUSION_MATRIX") . By default names of the tables are derived from the test metrics name using constant suffixes as follows:

• _CFM for Confusion Matrix
• _LFT for Lift
• _ROC for ROC

getTableName

public java.lang.String getTableName(javax.datamining.supervised.classification.ClassificationTestMetricOption testMetric)

Returns name of the table associated with a ClassificationTestMetricOption.
