High dimensional data analysis for predictive modeling is both challenging and valuable. A recent extension of the gradient boosting approach, Extreme Gradient Boosting (XGBoost), shows great promise in this area as demonstrated by its success in numerous Kaggle competitions. This presentation will outline XGBoost and illustrate its use in the development of a predictive model applied to customer database scoring.
