@daniloascione are you able to update this? I'd like to target for `2.3`.
But, can we do the following:
1. Port over ranking metrics (udfs) to `ml` with the `RankingEvaluator` as
you've done, but _excluding_ MPR
2. Also don't make any logic changes for the metrics calculation
Let's focus on porting things over and getting the API right. Then create
follow up tickets for additional metrics (MPR and any others) as well as
looking into correcting the logic and/or naming of the existing metrics.
Thanks!
