The DBMS_DATA_MINING_TRANSFORM package contains routines that perform data transformations such as binning, normalization, and outlier treatment. The package includes routines for:
Specifying transformations in a format that can be embedded in a mining model
Specifying transformations as relational views (external to mining model objects)
Specifying distinct properties for columns in the build data. For example, you can specify that the column should be interpreted as unstructured text, or that the column should be excluded from Automatic Data Preparation.
