Hi Prudvi.
What exactly do you mean by that?
There is regularization in the new HistGradientBoosting, and we're working on post-pruning for decision trees. I'm not sure what l2 regularization for decision tree classifiers or for decision tree regressors would mean. Do you have a reference?

Best,
Andy

Hi All,

I've noticed that there is no regularization term for Decision Tree
estimators in scikit learn. Are there any plans to introduce that?

Thanks
