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