Class DiscreteToContinuousModifier

java.lang.Object

magpie.data.utilities.modifiers.BaseDatasetModifier

magpie.data.utilities.modifiers.DiscreteToContinuousModifier

All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable, Options

public class DiscreteToContinuousModifier
extends BaseDatasetModifier

Convert multiple, discrete class values to single continuous class. Converts class values to the probability of an entry being a user-specified class.

If dataset is a MultiPropertyDataset and you are using a property as the class variable, this modifier will store result as a new property.

Usage: <class name>
class name: New value will be probability of entry being this class
