Struct Gradient Boosting &nbsp; Copy item path

impl GradientBoosting

pub fn fit_regressor( x: &[f64], y: &[f64], n: usize, p: usize, n_estimators: usize, learning_rate: f64, params: TreeParams, ) -> Result<Self, LearningError>

Fit n_estimators shallow trees by stage-wise residual fitting. learning_rate (ν, typically 0.05–0.3) shrinks each tree’s contribution. Fails closed on shape mismatch / empty ensemble / non-positive learning rate.

pub fn predict_row(&self, q: &[f64]) -> f64

pub fn predict(&self, x: &[f64], m: usize) -> Vec<f64>

pub fn n_estimators(&self) -> usize
