Problem getPredictedLabel() method

Question

Hi, i tried to compare the label and the prediction value of the r
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?

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

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
