WebJun 12, 2024 · An Introduction to Gradient Boosting Decision Trees. June 12, 2024. Gaurav. Gradient Boosting is a machine learning algorithm, used for both classification and regression problems. It works on the principle that many weak learners (eg: shallow trees) can together make a more accurate predictor. WebJan 11, 2024 · 1. Decision Tree Algorithm. While Decision Trees can be used for regression (predicting a continuous real-valued target, e.g. predicting car prices, given features), in this tutorial we will only be considering Decision Trees for classification (predicting discrete categories of target, e.g. predicting type of fruits, given features).
