Normalization

Normalization consists of transforming numerical values into a specific range, such as [–1.0,1.0] or [0.0,1.0] such that x_new = (x_old-shift)/scale. Normalization applies only to numerical attributes.

Oracle Data Miner allows you to specify these kinds of normalization:

provides transformations that perform min-max normalization, scale normalization, and z-score normalization.

You cannot normalized character data.
