Column role "weight" #1016

Open sebffischer opened 2 months ago

sebffischer commented 2 months ago

Currently it only says "Observation weights. Not more than one numeric column may have this role." in the Task documentation. Also, I got the reasonable question whether these are also applied during resampling.

There is a very old and open PR regarding weights for resampling: https://github.com/mlr-org/mlr3/pull/239

Also it was asked whether the weights are applied when scoring predictions via measures.
