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
cb.cv.predict Callback closure for returning cross-validation based predictions.
getinfo Get information of an xgb.DMatrix object
xgb.attr Accessors for serializable attributes of a model.
xgb.DMatrix.save Save xgb.DMatrix object to binary file
dimnames.xgb.DMatrix Handling of column names of xgb.DMatrix
cb.save.model Callback closure for saving a model file.
cb.early.stop Callback closure to activate the early stopping.
slice Get a new DMatrix containing the specified rows of original xgb.DMatrix object
dim.xgb.DMatrix Dimensions of xgb.DMatrix
setinfo Set information of an xgb.DMatrix object
cb.evaluation.log Callback closure for logging the evaluation history
xgb.load Load xgboost model from binary file
xgb.gblinear.history Extract gblinear coefficients history.
prepare.ggplot.shap.data Combine and melt feature values and SHAP contributions for sample observations.
xgb.DMatrix Construct xgb.DMatrix object
xgb.Booster.complete Restore missing parts of an incomplete xgb.Booster object.
xgb.ggplot.deepness Plot model trees deepness
xgboost-deprecated Deprecation notices.
xgb.ggplot.importance Plot feature importance as a bar graph
xgb.config Accessors for model parameters as JSON string.
xgb.create.features Create new features from a previously learned model
xgb.model.dt.tree Parse a boosted tree model text dump
print.xgb.Booster Print xgb.Booster
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.load.raw Load serialised xgboost model from R's raw vector
normalize Scale feature value to have mean 0, standard deviation 1
predict.xgb.Booster Predict method for eXtreme Gradient Boosting model
cb.gblinear.history Callback closure for collecting the model coefficients history of a gblinear booster during its training.
xgb.importance Importance of features in a model.
xgb.train eXtreme Gradient Boosting Training
xgb.parameters<- Accessors for model parameters.
xgb.cv Cross Validation
xgb.unserialize Load the instance back from xgb.serialize
xgb.ggplot.shap.summary SHAP contribution dependency summary plot
xgb.plot.multi.trees Project all trees on one tree and plot it
xgb.plot.shap SHAP contribution dependency plots
xgb.plot.tree Plot a boosted tree model
xgb.dump Dump an xgboost model in text format.
xgb.shap.data Prepare data for SHAP plots. To be used in xgb.plot.shap, xgb.plot.shap.summary, etc. Internal utility function.
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.
agaricus.test Test part from Mushroom Data Set
callbacks Callback closures for booster training.
cb.print.evaluation Callback closure for printing the result of evaluation
cb.reset.parameters Callback closure for resetting the booster's parameters at each iteration.
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.
agaricus.train Training part from Mushroom Data Set
print.xgb.DMatrix Print xgb.DMatrix
print.xgb.cv.synchronous Print xgb.cv result
