Describe the workflow you want to enable
I want to enable non-accuracy metrics to estimator.score, and ultimately deprecate the default values of accuracy and r2. I would call it scoring though it's a bit redundant but consistent.
That would allow us to get rid of the default scoring methods, which are objectively bad and misleading, and it would require the minimum amount of code changes for anyone.
Describe your proposed solution
Replace
est.score(X, y)with
est.score(X, y, scoring="accuracy")or rather
est.score(X, y, scoring="recall_macro")(or r2 for regression).
Describe alternatives you've considered, if relevant
- Keep current status, which is bad (both
accuracyandr2are bad) - Remove
scoringmethod.
I can't think of any other alternatives tbh.
Additional context
I think in theory this requires a slep, as it's changing shared API, right?
