Member Function Documentation

int kddml.Core.DataMining.ClassificationTrees.ConfusionMatrixManager.getNumberOfPredictions  ) 
 

Returns the total number of predications.

Returns:
int

Implemented in kddml.Core.DataMining.ClassificationTrees.ConfusionMatrix.

String [] kddml.Core.DataMining.ClassificationTrees.ConfusionMatrixManager.getCategories  ) 
 

Returns the categories of the target attribute.

Returns:
String[]

Implements kddml.Core.DataMining.CategoryMatrixManager.

Implemented in kddml.Core.DataMining.ClassificationTrees.ConfusionMatrix.

double kddml.Core.DataMining.ClassificationTrees.ConfusionMatrixManager.getPercentageAccuracy  ) 
 

Returns the ratio of the sum of the diagonal entries to the sum of all entries. The output value is a number between 0 and 1.

Returns:
double

Implemented in kddml.Core.DataMining.ClassificationTrees.ConfusionMatrix.

double kddml.Core.DataMining.ClassificationTrees.ConfusionMatrixManager.getPercentageError  ) 
 

Returns the sum of the non-diagonal sums where the actual value does not equal to predicted value, divided by the sum of all cells. The output value is a number between 0 and 1.

Returns:
double

Implemented in kddml.Core.DataMining.ClassificationTrees.ConfusionMatrix.

int kddml.Core.DataMining.ClassificationTrees.ConfusionMatrixManager.getIncorrectlyPredictions  ) 
 

Returns the total number of the incorrectly predictions related to this confusion matrix.

Returns:
int

Implemented in kddml.Core.DataMining.ClassificationTrees.ConfusionMatrix.
