Do you think a better idea might be to provide a different overload of Classify() that returns the confidence scores? Take a look at how this is done for the Hoeffding tree:

https://github.com/mlpack/mlpack/blob/master/src/mlpack/methods/hoeffding_trees/hoeffding_tree.hpp#L271

This way you can avoid holding an extra member in the NaiveBayesClassifier class.
