Retrieving Class Distribution

harry_wedemeije

When working with WEKA model it is possible to classify an instance,
and this can be translated to the RapidMiner model.apply(ExampleSet) method.

But in WEKA I can also retrieve the class distribution of a model, through
the method model.distributionForInstance(Instance).

How can I retrieve the class distribution for a RapidMiner model, given an Example.

Thanks,

For this purpose you can use the confidences of the prediction. The distribution is read from the model prediction and stored in the special attributes "confidence(v1)", "confidence(v2)"....
