Using an Analysis node

You can assess the accuracy of the model by using an Analysis node. From the Palette, under Outputs, place an Analysis node on the canvas and attach it to the C5.0 model nugget. Hover over the Analysis node and click the Run icon .

The Analysis node output shows that with this artificial dataset, the model correctly predicted the choice of drug for every record in the dataset. With a real dataset you are unlikely to see 100% accuracy, but you can use the Analysis node to help determine whether the model is acceptably accurate for your particular application.
