Interface ICategoricalAttribute

  • All Superinterfaces:
    IAttribute, java.io.Serializable
    public interface ICategoricalAttribute
extends IAttribute
    Categorical attributes are, by definition, a set of pairs of integers and some string label. It is clear that, for memory efficiency, categories should internally never be handled on the String basis but with internal Integer representations. Therefore, a categorical attribute has numeric VALUES (usually byte, short, or int) and string LABELS.
