You can specify recode schemes for numeric and character string attributes; only these attributes are displayed.
Note: Recode works best with attributes of fairly low cardinality, that is, attributes with a relatively small number of distinct values. Oracle Data Miner does not allow you to define recode schemes for attributes with with more than 2000 distinct values. For attributes with more than 2000 distinct values, use discretization (binning) or the missing values transformation.
Recode schemes are defined one attribute at a time. To define a recode scheme for an attribute, select it and click Define.
You can copy and paste a recode scheme from one attribute to one or more attributes using Copy and Paste. Copy and paste require that the source and destination attributes are the same datatype. Copy and Paste are context sensitive: Copy is enabled only if one attribute is selected; Paste is enabled only if at least one destination attribute is selected and if all selected attributes have the same datatype as the source attribute.
To delete a defined recode scheme, select the attributes and click Use Clear.
Use Select All to select all attributes and Clear All to delete all recode schemes.
Click Next when you have finished defining recode schemes. The wizard performs the following validations:
