class (Classifier model, Ring model ~ Label (Datapoint model)) => Regression model Source
this is a default instance that any instance of Classifier should satisfy if it is also an instance of ProbabilityClassifier instance ( Label (Datapoint model) ~ Datapoint (ResultDistribution model) , Mean (ResultDistribution model) , ProbabilityClassifier model ) => Classifier model where classify model dp = mean $ probabilityClassify model dp
Regression is classification where the class labels are (isomorphic to) real numbers. The constraints could probably be better specified, but they're close enough for now.
