More details below. Before we get started, XGBoost is a gradient boosting library with focus on tree models, which means inside XGBoost, there are 2 distinct parts: The model consisting of trees and . XGBoost is normally used to train gradient-boosted decision trees and other gradient boosted models. Random Forests use the same model representation and inference, as gradient-boosted decision . This is a quick start tutorial showing snippets for you to quickly try out XGBoost on the demo dataset on a binary classification task. Links to Other Helpful Resources
Now that you understand what boosted trees are, you may ask, where is the introduction for XGBoost? XGBoost is exactly a tool motivated by the formal principle introduced in this tutorial! Starting from version 1.6, XGBoost has experimental support for multi-output regression and multi-label classification with Python package. Multi-label classification usually refers to targets that have . It is very simple to enforce feature interaction constraints in XGBoost. Here we will give an example using Python, but the same general idea generalizes to other platforms.
XGBoost accepts parameters to indicate which feature is considered categorical, either through the dtypes of a dataframe or through the feature_types parameter. However, except for the Python . XGBoost has 3 builtin tree methods, namely exact, approx and hist. Along with these tree methods, there are also some free standing updaters including refresh, prune and sync. The parameter .
