What is XG Boost?

XGBoost (Extreme Gradient Boosting) is an optimized distributed gradient boosting library designed to be highly efficient, flexible, and portable. It implements machine learning algorithms under the Gradient Boosting framework. XGBoost provides a parallel tree boosting (also known as Gradient Boosting Machine) that solves many data science problems in a fast and accurate way. It is commonly used for classification, regression, and ranking tasks, often achieving state-of-the-art results.
