I've a binary classification problem which I want to solve where many features have a lot of NaN entriesmissing values.
I know that imputing with mean/median/variance is a solution, but I'd like to run tests only with the original dataset without imputing. XGBoost allows the usagepresence of NaN valesmissing values, while all the scikit-learn algorithms don't (correct me if I'm wrong), even if theoretically algorithm like random forest could accept NaNsmissing values.
Other than XGBoost, which other python classification algorithms implementations allow the usage of a dataset with NaN entriesmissing values?
