> Currently, FlinkML lacks means to evaluate the performance of trained models. 
> It would be great to add some {{Evaluators}} which can calculate some score 
> based on the information about true and predicted labels. This could also be 
> used for the cross validation to choose the right hyper parameters.
> Possible scores could be F score [1], zero-one-loss score, etc.
