OraTransformation

public interface OraBinningTransform

extends OraTransformation

Binning involves mapping both continuous and discrete values to discrete values of reduced cardinality. For example, the age of persons can be binned into discrete numeric bins: 1-20 to 1, 21-40 to 2, and so on. Popular car manufacturers such as Ford, Chrysler, BMW, Volkswagen can be binned into discrete categorical bins: {Ford, Chrysler} to US_Car_Makers, and {BMW, Volkswagen} to European_Car_Makers. The package supports binning for both categorical and numerical attributes. This interface defines the methods to set bin details of the transformation.
