  # NAME
  
  Algorithm::XGBoost - A Raku bindings for XGBoost ( <https://github.com/dmlc/xgboost> ).
  
  # SYNOPSIS
  
  ```
  use Algorithm::XGBoost;
  use Algorithm::XGBoost::Booster;
  use Algorithm::XGBoost::DMatrix;
  use Algorithm::XGBoost::Model;
  
  # agaricus.txt.test is here: https://github.com/dmlc/xgboost/tree/master/demo/data
  my $dmat = Algorithm::XGBoost::DMatrix.from-file("agaricus.txt.train");
  say $dmat.num-row; # 6513
  say $dmat.num-col; # 127
  my $model = Algorithm::XGBoost.train($dmat, 10);
  $model.num-feature.say; # 127
  
  my @test[2;2] = [[0e0,0e0],[0e0,1e0]];
  my $test = Algorithm::XGBoost::DMatrix.from-matrix(@test);
  say $model.predict($test); # (0.9858561754226685 0.9858561754226685)

  # DESCRIPTION
  
  Algorithm::XGBoost is a Raku bindings for XGBoost ( <https://github.com/dmlc/xgboost> ).
  
  ## METHODS
  
  ### train
  
  Defined as:
  
  ```
  method train(Algorithm::XGBoost::DMatrix $dmat, Int $num-iteration, %param --> Algorithm::XGBoost::Model)
  
  ```
  
  Trains a XGBoost model.
  
  * `$dmat` The instance of Algorithm::XGBoost::DMatrix.
  * `$num-iteration` The number of iterations for training.
  * `%param` The parameter for training.
  
  ### version
  
  Defined as:
  
  ```
  method version(--> Version)
  
  ```
  
  Returns the libxgboost version.
  
  ### global-config
  
  Defined as:
  
  ```
  multi method global-config(Str $json-str)
  multi method global-config(--> Str)
  
  ```
  
  Sets/Gets the global parameters: verbosity and use\_rmm.
  
  * `verbosity` The verbosity of printing messages. Valid values of 0 (silent), 1 (warning), 2 (info), and 3 (debug).
  * `use_rmm` Whether to use RAPIDS Memory Manager (RMM) to allocate GPU memory. This option is only applicable when XGBoost is built (compiled) with the RMM plugin enabled. Valid values are true and false.
