Technical Definition
An optimized distributed gradient boosting library designed for speed and performance.
How it works
XGBoost, short for eXtreme Gradient Boosting, is a popular open-source software library that implements a highly efficient and regularized gradient boosting framework. It is widely used for supervised learning tasks, particularly in predictive modeling and data science competitions, due to its speed, performance, and ability to handle large datasets. XGBoost incorporates various optimizations and regularization techniques to prevent overfitting and improve accuracy.
