How does predict with ensemble regression works?

2 views (last 30 days)
This might be a silly question...iam using bagging with regression trees. I built for instance 10 different trees, then I average them. when I then use predict to predict my y value, how does it work? does it somehow average the fitted y values?!
thanks for your help!!

For classification the output of the ensemble is the class that gets majority vote from all the learners. For regression the results are averaged.

Short answer is yes.
However if you want a more accurate y you have to look into boosting.
