Interface SVMClassificationSettings

All Superinterfaces:

AlgorithmSettings, SupervisedAlgorithmSettings

public interface SVMClassificationSettings

extends SupervisedAlgorithmSettings

An SVMClassificationSettings object captures the parameters associated with the SVM classification algorithm. It allows a knowledgeable user to fine tune algorithm parameters. Generally, not all parameters must be specified, however, those specified are taken into account by the underlying data mining system.
