Learn() публичный статический Метод

Generate a multi-class classification model using a specialist classifier for each class label.
public static Learn ( IGenerator generator, IEnumerable examples, double trainingPercentage, double mixingPercentage = 0.5, bool isMultiClass = true ) : ClassificationModel
generator IGenerator The generator to use for each individual classifier.
examples IEnumerable Training examples of any number of classes
trainingPercentage double Percentage of training examples to use, i.e. 70% = 0.7
mixingPercentage double Percentage to mix positive and negative exmaples, i.e. 50% will add an additional 50% of /// of negative examples into each classifier when training.
isMultiClass bool Determines whether each class is mutually inclusive. /// For example: If True, each class takes on a number of classes and does not necessarily belong to one specific class. /// The ouput would then be a number of predicted classes for a single prediction. E.g. A song would be True as it may belong to classes: vocals, rock as well as bass. ///
