Welcome to the Mining test activity Wizard

Use this wizard to create a test activity to test an Oracle Data Mining model. You can create a test activity for classification and regression models.

You can create a test activity for either

You test a model by applying the model to data for which you know the target value. You then evaluate the model by comparing predicted values to actual values. One common way to create data for testing is to split the data set used to build the model.

Data used to test a model must be compatible with the data used to build the model.

Data used to test a model must be prepared in exactly the same way as the data used to build the model. For example, if the data used to build the model is normalized, data used to test the model must be normalized in the same way.

If a model was created using a build activity, the test activity prepares the data using the preparation steps in the build activity. If you select a model that was not created through a build activity, you must ensure that the test data is prepared in the same way that the build data was prepared.

The welcome page of the wizard contains a brief description of a test activity. For more information about mining activities, see Mining Activity Overview.

You can create a test activities for classification and regression models only.
