Binning Methods

This topic describes the binning methods supported by Oracle Data Miner for numerical and categorical attributes. For information about interval notation, see Interval Notation.

Binning Numerical Attributes

Oracle Data Miner supports these methods for binning numerical attributes:

Quantile binning creates bins with approximately equal numbers of cases in each bin, irrespective of the width of the numerical range. Equal Width binning creates bins of identical width, irrespective of the number of cases in each bin; note that this strategy could generate empty bins.

Binning Categorical Attributes

Oracle Data Miner supports this method for binning categorical attributes:

There is also a binning strategy of None for categorical attributes, that is, do not bin the attribute.
