[jira] [Created] (FLINK-2157) Create evaluation framework for ML
library
Till Rohrmann created FLINK-2157:
------------------------------------
Summary: Create evaluation framework for ML library
Key: FLINK-2157
URL: https://issues.apache.org/jira/browse/FLINK-2157
Project: Flink
Issue Type: New Feature
Components: Machine Learning Library
Reporter: Till Rohrmann
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.
