Advanced Settings

To view which columns are selected by Oracle Data Miner and what mining type is assigned to each selected column, follow these steps:

1. Connect the Data Source node to the Model node.

2. Right-click the Model node and select Run.

3. Open the Advanced Settings dialog box in one of these ways:

   • After the model build completes, right-click the Model node and select Edit.

     The Edit dialog box opens. Click Advanced.

   • After the model build completes, right-click the Model node and select Advanced Settings.

4. The Advanced Settings has two grids:

   • The Model Settings grid: The grid at the top lists the models built by the node.

   • The lower part of the dialog box is a tabbed display of the following:

     • Data Usage: The Data Usage tab displays information about which columns are selected for Model build, the mining type used for model building for each column, Data Type, Input, Auto Data Prep, and Rules.
       To view the details about the rules (Heuristics), click Show.

     • Algorithm Settings

     • Performance Settings

5. To view which columns are used as input for the Model build, select the model. In the Data Usage tab, the attributes used in model build rules indicate the heuristics applied to the attribute. For example, the mining type may be changed. For details, click Show.

6. You can change data usage information on a per-model basis, or you can change the data usage for several models at the same time.

   To change data usage for several models, select the models by pressing the Ctrl key and clicking it simultaneously. Make the changes and click OK. The changes are made to the data usage for all selected models.
