public class ClassificationTestResult

extends MiningTestResult

An instance of ClassificationTestResult represents the result of the test operation for a classification model. It contains an estimated accuracy value and a confusion matrix. The confusion matrix looks like Predicted Yes No Acutal Yes 0 5 Acutal No 500 0 From the above matrix table, we can see that (Category row, Category column) will have the following Confusion Matrix values: Confusion Matrix of (Actual Yes, Predicted Yes) = 0 Confusion Matrix of (Actual Yes, Predicted No) = 5.00 Confusion Matrix of (Actual No, Predicted Yes) = 500.00 Confusion Matrix of (Actual No, Predicted No) = 0

Since:

9.0.1
