Public Methods

Method	Description
AccuracyOn ( this classifier, IEnumerable labeledExamples ) : double	Computes the classifier's accuracy in predicting the set of examples
AsOnlineClassifier ( this classifier ) : IOnlineClassifier	Wraps the classifier in an online classifier which works by storing all input examples and retraining the classifier on the stored examples as well as the new examples on each call to TrainMore
ErrorOn ( this classifier, IEnumerable labeledExamples ) : double	Computes the classifier's error in predicting the set of examples
IsNegative ( this classifier, Example example ) : bool	As `classifier.IsNegative(classifier, example.Class)`
IsNegative ( this classifier, int cls ) : bool	Does cls currently map to a negative example in this classifier?
IsPositive ( this classifier, Example example ) : bool	As `classifier.IsPositive(classifier, example.Class)`
IsPositive ( this classifier, int cls ) : bool	Does cls currently map to a positive example in this classifier?
Predict ( this classifier, IEnumerable examples ) : IEnumerable>	Returns a Trio of (example, predicted class, confidence) for each example
Predict ( this classifier, Example example ) : int	Predict without the confidence parameter
TrainMore ( this classifier, Example labeledExample ) : void	TrainMore, but with a single example
