Solution
The type of Ensemble modeling approach that is NOT a special case of model averaging is Boosting methods.
Here's why:
-
Model averaging is a method where multiple models are trained to predict the same output variable, then their predictions are averaged in some way to give the final prediction.
-
Random Forest methods, Bagging method of Bootstrap aggregation, and the Pasting method of Bootstrap aggregation all involve creating multiple models and averaging their predictions.
-
However, Boosting methods are different. Instead of creating models independently and then averaging their predictions, boosting methods create models sequentially, where each new model is trained to correct the errors made by the previous models. Therefore, boosting methods are not a special case of model averaging.
