Description
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.
Prediction
Encapsulates a single evaluatable prediction: the predicted 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.
