Package weka.classifiers.evaluation

Interface Summary

Prediction

Encapsulates a single evaluatable prediction: the predicted value plus the actual class value.

Class Summary

ConfusionMatrix	Cells of this matrix correspond to counts of the number (or weight) of predictions for each actual value / predicted value combination.
CostCurve	Generates points illustrating probablity cost tradeoffs that can be obtained by varying the threshold value between classes.
EvaluationUtils	Contains utility functions for generating lists of predictions in various manners.
MarginCurve	Generates points illustrating the prediction margin.
NominalPrediction	Encapsulates an evaluatable nominal prediction: the predicted probability distribution plus the actual class value.
NumericPrediction	Encapsulates an evaluatable numeric prediction: the predicted class value plus the actual class value.
ThresholdCurve	Generates points illustrating prediction tradeoffs that can be obtained by varying the threshold value between classes.
TwoClassStats	Encapsulates performance functions for two-class problems.
