Machine Learning for Data Mining

Combining models outside Modeler

This method can be used when you are using any data-mining software other than SPSS Modeler.

Let's see how to do that:

1. Go to the Field Ops palette and connect the SVM-generated model to a Derive node.
2. We will use the Derive node to create a new field. We will edit this node and name it Combined_Prediction.
3. Derive this field as a Conditional. You will see an if-else condition.
4. Let's tell Modeler that if the predictions from all the models are equal then the combined prediction will be that prediction itself. To do this, let's add an expression in the first if condition as, the prediction from the Neural Net model, $N-Status select = the prediction of the SVM model, $S-Status; go to the Then condition, click ...
