Struct BaggingHelper

Source

pub struct BaggingHelper {
    pub n_estimators: usize,
    pub random_seed: u64,
}

Expand description

Bagging (Bootstrap Aggregating) utilities.

Generates bootstrap samples for training ensemble members.

Fields§

§n_estimators: usize

Number of bootstrap samples.

§random_seed: u64

Random seed for reproducibility.

Implementations§

Source §

impl BaggingHelper

Source

pub fn new(n_estimators: usize, random_seed: u64) -> TrainResult<Self>

Create a new bagging helper.

§Arguments

n_estimators - Number of bootstrap samples
random_seed - Random seed

Source

pub fn generate_bootstrap_indices( &self, n_samples: usize, estimator_idx: usize, ) -> Vec<usize>

Generate bootstrap sample indices.

§Arguments

n_samples - Total number of samples
estimator_idx - Index of the estimator (for seeding)

§Returns

Bootstrap sample indices (with replacement)

Source

pub fn get_oob_indices( &self, n_samples: usize, bootstrap_indices: &[usize], ) -> Vec<usize>

Get out-of-bag (OOB) indices for an estimator.

§Arguments

n_samples - Total number of samples
bootstrap_indices - Bootstrap sample indices

§Returns

OOB sample indices (not in bootstrap sample)
