Feb 10, 2025 · XGBoost – XGBoost is an optimized implementation of Gradient Boosting that uses regularization to prevent overfitting. XGBoost: XGBoost, short for “Extreme Gradient Boosting,” is like a team of miners, each equipped with a magical pickaxe that can learn from the mistakes of the miner before them. Oct 9, 2024 · XGBoost Regression is an implementation of the XGBoost algorithm used for predicting continuous target variables (regression tasks). The XGBoost algorithm is known for its impressive performance and versatility. Some unique features of XGBoost: Regularization: XGBoost models are extremely complex and use different types of regularization like Lasso and Ridge etc to penalize the highly complex models The two main factors to choose XGBoost over other algorithms are: Execution Speed; Model Performance; Let us look at these points in brief. fname (string) – Output file name. CatBoost is preferred when dealing with datasets containing categorical features, as it automatically handles them without preprocessing. XGBoost is an optimized distributed gradient boosting library designed to be highly efficient, flexible, and portable. Due to this, XGBoost performs better than a normal gradient boosting algorithm and that is why it is much faster than that also. How XGBoost Works.
