To edit a Clustering Query node:

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

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

   • Cluster 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 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 Number of Clusters to Compute field, specify the number to compute. Default is 10.

     • Edit Cluster Prediction Outputs. Oracle Data Miner automatically determines the output for the query. 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.

     • Select Partitions: To select partitions, click the Partitions tab. Then, click . Then use the Add Partitioning Columns to select the partitions. You can also specify partitioning expressions.

   • Input tab: You can modify Input. This is optional. You can add or remove inputs and change the mining types of inputs. Click Input.

   • 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.
