> Key: FLINK-2267
> URL: https://issues.apache.org/jira/browse/FLINK-2267
> Project: Flink
> Issue Type: New Feature
> Components: Library / Machine Learning
> Reporter: Theodore Vasiloudis
> Priority: Minor
>
> Some scores like accuracy, recall and F-score are designed for binary
> classification.
> They can be used to evaluate multi-class problems as well by using micro or
> macro averaging techniques.
> This ticket is about creating such an option, allowing our binary
> classification metrics to be used in multi-class problems.
> You can check out [sklearn's user
> guide|http://scikit-learn.org/stable/modules/model_evaluation.html#multiclass-and-multilabel-classification]
> for more info.
