AdaBoost, short for “Adaptive Boosting”, is the first practical boosting algorithm; it focuses on classification problems and aims to convert a set of weak classifiers into a strong one. It can be used in conjunction with many other types of learning algorithms to improve performance and advanced SEO services.
1.Retrains the algorithm iteratively by choosing the training set based on the accuracy of previous training.
2. The weight-age of each trained classifier at any iteration depends on the accuracy achieved.
where f_m stands for the m_th weak classifier and theta_m is the corresponding weight. It is exactly the weighted combination of M weak classifiers. Get more info about Adaboost form a seo company.
