Direct Known Subclasses:

LogisticRegressionModel

public abstract class SimpleBinaryPredictionModel
extends PredictionModel

A model that can be applied to an example set by applying it to each example separately. In contrast to the usual SimplePredictionModel, this model should only be used for binary classification problems. The method predict(Example) must deliver a function value. A value greater than 0 will be mapped to the positive class, a value smaller than 0 to the negative class index. The confidence values will be calculated by the fast and simple scaling suggested by Rueping.
