Extreme Gradient Boosting

Extreme Gradient Boosting, which is an efficient implementation of the gradient boosting framework from Chen & Guestrin (2016) <doi:10.1145/2939672.2939785>. This package is its R interface. The package includes efficient linear model solver and tree learning algorithms. The package can automatically do parallel computation on a single machine which could be more than 10 times faster than existing gradient boosting packages. It supports various objective functions, including regression, classification and ranking. The package is made to be extensible, so that users are also allowed to define their own objectives easily.

Functions in xgboost

Name Description
prepare.ggplot.shap.data Combine and melt feature values and SHAP contributions for sample observations.
dim.xgb.DMatrix Dimensions of xgb.DMatrix
dimnames.xgb.DMatrix Handling of column names of xgb.DMatrix
getinfo Get information of an xgb.DMatrix object
cb.save.model Callback closure for saving a model file.
print.xgb.cv.synchronous Print xgb.cv result
print.xgb.DMatrix Print xgb.DMatrix
cb.early.stop Callback closure to activate the early stopping.
xgb.create.features Create new features from a previously learned model
xgb.config Accessors for model parameters as JSON string.
xgb.cv Cross Validation
xgb.dump Dump an xgboost model in text format.
xgb.model.dt.tree Parse a boosted tree model text dump
xgb.parameters<- Accessors for model parameters.
xgb.ggplot.deepness Plot model trees deepness
xgb.ggplot.importance Plot feature importance as a bar graph
predict.xgb.Booster Predict method for eXtreme Gradient Boosting model
xgb.plot.multi.trees Project all trees on one tree and plot it
normalize Scale feature value to have mean 0, standard deviation 1
xgb.DMatrix.save Save xgb.DMatrix object to binary file
xgb.attr Accessors for serializable attributes of a model.
xgb.serialize Serialize the booster instance into R's raw vector. The serialization method differs from xgb.save.raw as the latter one saves only the model but not parameters. This serialization format is not stable across different xgboost versions.
xgb.shap.data Prepare data for SHAP plots. To be used in xgb.plot.shap, xgb.plot.shap.summary, etc. Internal utility function.
slice Get a new DMatrix containing the specified rows of original xgb.DMatrix object
setinfo Set information of an xgb.DMatrix object
xgb.ggplot.shap.summary SHAP contribution dependency summary plot
xgb.gblinear.history Extract gblinear coefficients history.
xgb.plot.shap SHAP contribution dependency plots
xgb.save Save xgboost model to binary file
xgb.save.raw Save xgboost model to R's raw vector, user can call xgb.load.raw to load the model back from raw vector
xgb.importance Importance of features in a model.
xgb.load.raw Load serialised xgboost model from R's raw vector
xgb.load Load xgboost model from binary file
xgb.plot.tree Plot a boosted tree model
xgb.DMatrix Construct xgb.DMatrix object
print.xgb.Booster Print xgb.Booster
xgb.train eXtreme Gradient Boosting Training
xgb.unserialize Load the instance back from xgb.serialize
xgb.Booster.complete Restore missing parts of an incomplete xgb.Booster object.
xgboost-deprecated Deprecation notices.
cb.cv.predict Callback closure for returning cross-validation based predictions.
callbacks Callback closures for booster training.
agaricus.train Training part from Mushroom Data Set
agaricus.test Test part from Mushroom Data Set
a-compatibility-note-for-saveRDS-save Do not use saveRDS or save for long-term archival of models. Instead, use xgb.save or xgb.save.raw.
cb.print.evaluation Callback closure for printing the result of evaluation
cb.gblinear.history Callback closure for collecting the model coefficients history of a gblinear booster during its training.
cb.reset.parameters Callback closure for resetting the booster's parameters at each iteration.
cb.evaluation.log Callback closure for logging the evaluation history
