public class OraClassificationTestMetricsTask

extends OraClassificationTestTask

implements javax.datamining.supervised.classification.ClassificationTestMetricsTask

ClassificationTestMetricsTask is a mining task used for computing and creating test metrics objects given an apply output data. The results of executing a classification test metrics task is a ClassificationTestMetrics object.

Executing a ClassificationTestMetricsTask task without any metrics to be computed results in an exception.

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

Overrides:

setTableName in class OraClassificationTestTask

getTableName

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

Returns name of the table associated with a ClassificationTestMetricOption.

Overrides:

getTableName in class OraClassificationTestTask
