             Summary: Saving true and predicted labels to file
                 Key: SAMOA-68
                 URL: https://issues.apache.org/jira/browse/SAMOA-68
             Project: SAMOA
          Issue Type: New Feature
          Components: SAMOA-API
            Reporter: Maciej Grzenda


Currently PrequentialEvaluation task supports dumpFile option.  With this option model performance
can be saved to a file. However, in some cases it would be good to save also individual predictions
made by a model.  This is useful for model debugging and method development.
This could be also used to visualize model output, calculate custom performance indicators
(e.g. model accuracy for instances of a certain class or sharing the same feature value).
 Such saving of model output (if done) should be made for every instance. Hence, a new option
making it possible to dump predictions to a separate file seems justified.  For classification,
it should include votes made for individual classes, if available.
