Automatic Data Preparation

Most algorithms require some form of data transformation. During the model building process, Oracle Data Mining can automatically perform the transformations required by the algorithm. You can choose to supplement the automatic transformations with additional transformations of your own, or you can choose to manage all the transformations yourself.

If Automatic Data Preparation is performed, the same data preparation is automatically performed for data that is scored using the model. If Automatic Data Preparation is off, that is if you manage all the transformations yourself, you must prepare apply data in the same way that the build data was prepared.

In calculating automatic transformations, Oracle Data Mining uses heuristics that address the common requirements of a given algorithm. This process results in reasonable model quality in most cases.
