Model ensembling comprises a set of methods that aims to increase accuracy by combining the predictions of multiple models together.
Ensemble methods can be categorized based on their approach for combining classifiers: one approach is to use similar classifiers and to combine them together using techniques such as bagging, boosting or random forests. A second approach is to combine different classifiers using model stacking.
In this presentation I provide an example of model stacking applied to the classification of a Landsat image.
