Oracle Data Mining allows you to test classification and regression models. You cannot test other kinds of models.
Oracle Data Miner supports these ways to test a Classification or Regression models:
Test the model as part of the Build node. There are several ways to do this
Split the build data into build and test subsets.
Use all of the build data as test data.
Connect a second data source, the test data source. to the build node
For more information on these methods, see Test.
Test the model in a Test node. In this case, the test data can be any table that is compatible with the build data, as described in Evaluate and Apply Data.
Note: All of the models tested in a node must be either Classification or Regression models; you cannot test both kinds of models in the same test node. |
For more information about testing models, see Testing Classification Models or Testing Regression Models.
After you have tested a classification model, you can tune it as described in Tuning Classification Models. (You cannot tune regressions models.)
A Test Node can test several models using the same test set. See Test Node Input.
If Automatic Settings are on, the test node specification is generated when you connect the input nodes. For details, see Automatic Settings.
