Edit a Prediction Query

To edit a Prediction Query node:

  1. Double-click the Prediction Query node or right-click the node and click Edit. The Edit Prediction Query Node dialog box opens.

  2. In the Edit Prediction Query Node dialog box, enter the details in the following tabs:

    • Predictions tab:

      • In the Case ID field, select a case ID from the drop-down list. The case ID is optional. It is recommended that you specify a case ID to uniquely define each record. The case ID helps with model repeatability and is consistent with good data mining practices.

      • In the Targets section, you can add one or more targets. To add target, click add. Use the Add Target dialog box to define targets.

      • In the Targets section, change the Mining Type of a target, if necessary. Each attribute has an associated data type and mining type. The mining type defines how the attribute is treated in the predictive query.
        For Regression query analysis, the mining type must be Numerical.
        For Classification query analysis, the mining type must be Categorical.
        If you make changes, click OK.

      • In the Prediction Output section, you can edit the prediction output. Oracle Data Miner automatically determines the output for each target. You can modify the output.

    • Partition tab: You can perform the following tasks:

      • Add one or more Partition attributes. This is optional. Selecting a Partition attribute directs the predictive query to build a virtual model for each unique partition.
        To add partitions, click add. Use the Add Partitioning Columns dialog box to select partitions.

      • Specify partitioning expressions.

    • Input tab: You can perform the following tasks:

      • Modify input

      • Add or remove inputs

      • Change mining types of inputs

    • Additional Output tab: You can add outputs (optional). By default, all target columns, the Case ID column, and partitioning columns are automatically added to Additional Output. To make changes, click Additional Output.

  3. Click OK.
