It would be nice if it supports optional fit_param parameter, which will enhance the estimator.fit. For example, we can use lightgbm / xgboost or HistGradientBoosting early stopping fitting & sample_weight way to overcome the overfitting issue.

Attributes of base estimators in Regressor Chain - Stack Overflow

Web1 Answer. base_estimator is the parameter passed to RegressorChain, and remains unfitted when you fit the RegressorChain. That estimator gets cloned repeatedly, and each clone gets fitted (in turn, using the previously fitted clones' predictions as additional input).
