1 Introduction. XGBoost is an implementation of a machine learning technique known as gradient boosting. In this blog post, we discuss what XGBoost is, and demonstrate a pipeline for working with it in R. We wont go into too much theoretical detail. What should the subsample ratio be in XGBoost?What should the subsample ratio be in XGBoost?subsample The default value is set to 1. You need to specify the subsample ratio of the training instance. Setting it to 0.5 means that XGBoost randomly collected half of the data instances to grow trees and this will prevent overfitting. The range is 0 to 1. colsample_bytree The default value is set to 1.XGBoost In R A Complete Tutorial Using XGBoost In R Which is the booster to use in XGBoost?Which is the booster to use in XGBoost?You need to specify the booster to use gbtree (tree based) or gblinear (linear function). num_pbuffer This is set automatically by xgboost, no need to be set by user. Read documentation of xgboost for more details. num_feature This is set automatically by xgboost, no need to be set by user. eta The default value is set to 0.3.XGBoost In R A Complete Tutorial Using XGBoost In R

Why is sklearn's API of XGBoost preferable?Why is sklearn's API of XGBoost preferable?We use sklearn's API of XGBoost as that is a requirement for grid search (another reason why Bayesian optimization may be preferable, as it does not need to be sklearn-wrapped). You should consider setting a learning rate to smaller value (at least 0.01, if not even lower), or make it a hyperparameter for grid searching.Hyperparameter Grid Search with XGBoost Kaggle update XGBoost sample by numerology Pull An R Pipeline for XGBoost Part I R bloggers

The idea is to use XGBoost functionality (both training and prediction) via production environment-specific wrapper library, not directly. For example, in Python, you could use Scikit-Learn wrappers, which encapsulate feature engineering and -selection tasks into a reusable sklearn.pipeline.Pipeline object.
