Struct Bootstrap 

pub struct Bootstrap { /* private fields */ }

Bootstrap sample generator

Creates bootstrap samples (sampling with replacement) for ensemble methods.

Implementations

impl Bootstrap

pub fn new(n_samples: Option<usize>, random_state: Option<u64>) -> Self

Create a new bootstrap sampler

Arguments

• n_samples - Number of samples to draw (None = same as input size)
• random_state - Random seed for reproducibility

pub fn sample( &self, n_population: usize, ) -> UtilsResult<(Vec<usize>, Vec<usize>)>

Generate bootstrap sample indices

Arguments

• n_population - Size of the population to sample from

Returns

Tuple of (in-bag indices, out-of-bag indices)

pub fn sample_multiple( &self, n_population: usize, n_bootstraps: usize, ) -> UtilsResult<Vec<(Vec<usize>, Vec<usize>)>>

Generate multiple bootstrap samples

Arguments

• n_population - Size of the population
• n_bootstraps - Number of bootstrap samples to generate

Returns

Vector of (in-bag, out-of-bag) index pairs
