Classification Node Test

The test section specifies the data used for test and which tests to perform.

For more information about testing classification nodes, see Testing Classification Models.

You can specify no test.

The default is to test all models built using the test data that is created by randomly splitting the build data into two subsets.

By default, the test node performs these tests:

If you plan to tune the models, you must test the models in the build node, not in a Test node. You should also select Generate Selected Test Results for Tuning. See Tuning Classification Models for details.

Test Data is created is one of the following ways:

You can provide a separate test data source;. Select Use Test Data Source for Testing and connect the test data source to the build node after you connect the build data.

Another way to test a model is to use a Test Node.
