Description
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.
