Boosted C5.0 Models

This feature is available in SPSS® Modeler Professional and SPSS Modeler Premium.

When you create a boosted C5.0 model (either a rule set or a decision tree), you actually create a set of related models. The model rule browser for a boosted C5.0 model shows the list of models at the top level of the hierarchy, along with the estimated accuracy of each model and the overall accuracy of the ensemble of boosted models. To examine the rules or splits for a particular model, select that model and expand it as you would a rule or branch in a single model.

You can also extract a particular model from the set of boosted models and create a new Rule Set model nugget containing just that model. To create a new rule set from a boosted C5.0 model, select the rule set or tree of interest and choose either Single Decision Tree (GM Palette) or Single Decision Tree (Canvas) from the Generate menu.
