Struct BoosterParameters

pub struct BoosterParameters { /* private fields */ }

Parameters for training boosters. Created using BoosterParametersBuilder.

Implementations

impl BoosterParameters

pub fn booster_type(&self) -> &BoosterType

Get type of booster (tree, linear or DART) along with its parameters.

pub fn set_booster_type<T: Into<BoosterType>>(&mut self, booster_type: T)

Set type of booster (tree, linear or DART) along with its parameters.

pub fn learning_params(&self) -> &LearningTaskParameters

Get configuration for the learning objective.

pub fn set_learning_params<T: Into<LearningTaskParameters>>( &mut self, learning_params: T, )

Set configuration for the learning objective.

pub fn verbose(&self) -> bool

Check whether verbose output is enabled or not.

pub fn set_verbose(&mut self, verbose: bool)

Set to true to enable verbose output from XGBoost’s C library.

pub fn threads(&self) -> &Option<u32>

Get number of parallel threads XGBoost will use (if compiled with multiprocessing support).

If None, XGBoost will determine the number of threads to use automatically.

pub fn set_threads<T: Into<Option<u32>>>(&mut self, threads: T)

Set number of parallel threads XGBoost will use (if compiled with multiprocessing support).

If None, XGBoost will determine the number of threads to use automatically.
