       - Stacking trains a learning algorithm to combine the predictions of several other learning algorithms.
   Despite this method being developed at the start of the century, it is blazingly fast compared to some machine learning algorithms, and still widely used.
  4. Finally, this algorithm uses [Cascading Classifiers](https://en.wikipedia.org/wiki/Cascading_classifiers) to identify faces.  (See page 12 of the original paper for the specific cascade).
