The idea of boosting is to take a “weak classifier” — that is, any classifier that will do at least slightly better than chance — and use it to build a much better classifier, thereby boosting the performance of the weak classification algorithm. This boosting is done by averaging the outputs of a collection of weak classifiers. The most popular boosting algorithm is AdaBoost,…
