Direct Known Subclasses:

ConjunctiveRuleModel, DiscriminantModel, HyperplaneModel, MultiCriterionDecisionStumps.DecisionStumpModel, PolynomialRegressionModel, RuleModel, RuleSet, SimpleVoteModel, TreeModel

public abstract class SimplePredictionModel
extends PredictionModel

A model that can be applied to an example set by applying it to each example separately. Just as for the usual prediction model, subclasses must provide a constructor getting a label attribute which will be used to invoke the super one-argument constructor.
