Output exampleSet of a rapidminer process in java with the methods getlabel and getPredictedLabel but the latter return to me double value like 0.353 or 0.127 but the label is a polynamial type with value 0 and 1. In the gui i don't have this problem, why?

    Hey,

    internally polynominal values are mapped to doubles. To return the value as a String use ... 

    example.getValueAsString(example.getAttributes().getLabel());
    example.getValueAsString(example.getAttributes().getPredictedLabel());
    Best regards

    Thank you very much... Actually I knew that polynominal value were wapped in double but I didn't understand why with only two possible value the method returned many different double values
