How to use warm_start

Question

I\'d like to use the warm_start parameter to add training data to my random forest classifier. I expected it to be used like this:

clf = RandomF         


        

Answer 1

Just to add to excellent @sascha`s answer, this hackie method works:

rf = RandomForestClassifier(n_estimators=1, warm_start=True)                     
rf.fit(X_train, y_train)
rf.n_estimators += 1
rf.fit(X_train, y_train)
