NAME

====

Algorithm::XGBoost - A Raku bindings for XGBoost ( https://github.com/dmlc/xgboost ).

SYNOPSIS

========

```raku

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 = [[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.
