Data Used for Model Build

Data Miner does not necessarily use all of the columns in a data source when it builds models.

Build Model nodes use a set of heuristics to determine whether to exclude columns from the model building process or change the mining type (from numerical to categorical only):

To see which attributes are used to build a model and what the mining type of each attribute is, see Viewing and Changing Data Usage.

If you are connected to Oracle Database 12c, you can specify characteristics of Text attributes when you edit the build node, as described in Specify Text Characteristics.
