Hi all,We have managed to fit the ranking recommendation evaluation into the evaluation framework proposed by Thedore (FLINK-2157). There's one main problem, that remains: we have to different predictor traits (Predictor, RankingPredictor) without a common superclass, and that might be problematic.
Please see the details at the issue: https://issues.apache.org/jira/browse/FLINK-4713Could you give feedback on whether we are moving in the right direction or not? Thanks!
Cheers, Gabor
