Implement class_weight in HistGradientBoostingClassifier

See original GitHub issue

Just a reminder/note to implement class_weight [=“balanced”] for this new algorithm.

Looking forward to when this will be implemented.

If anyone has any interim suggestions for dealing with imbalanced data with this algorithm, include them below.

Cheers.

sample weights support will be available in 0.23 which should be out soon. So you can have class weights through that.

Just a reminder

they really need to do this

Let’s avoid that kind of phrasing please.

Happy to have sample_weights support, but that doesn’t really help for my use case. Class weights generally need to be tuned like a hyperparameter, and I can’t do that using, say, GridSearchCV because there is no class_weight param.
