WebApr 17, 2024 · Gradient boosting is a supervised learning algorithm that attempts to accurately predict a target variable by combining the estimates of a set of simpler, weaker models. This article will cover the XGBoost algorithm implementation and apply it to solving classification and regression problems. WebBoosting algorithms combine multiple low accuracy (or weak) models to create a high accuracy (or strong) models. It can be utilized in various domains such as credit, insurance, marketing, and sales. Boosting algorithms such as AdaBoost, Gradient Boosting, and XGBoost are widely used machine learning algorithm to win the data science competitions.
