5) When we used this data set previously, we added our Decision Tree operator at this point.
This time, we will use the search field in the Operators tab to find x-Validation operators.
There are four of them, but we will use the basic cross-validation operator in this example:
Figure 13-4. Adding a cross-validation operator to our stream.
6) The cross-validation operator requires a two-part sub-process. In the first part of the sub-
process, we will add our Decision Tree operator to build a model, and in the second part
we will apply our model and check its performance. Double click the Validation operator
to enter the sub-process window.
