Boosting (machine learning) WikipediaIn machine learning, boosting is an ensemble metaalgorithm for primarily reducing bias, and also variance in supervised learning, and a family of machine learning algorithms that convert weak learners to strong ones. Boosting is based on the question posed by Kearns and Valiant (1988, 1989) "Can a set of weak learners create a single strong learner?"
