Struct Fitted Gradient Boosting Classifier &nbsp; Copy item path

impl<F: Float> FittedGradientBoostingClassifier<F>

pub fn n_estimators(&self) -> usize

Number of estimators per class set.

pub fn classes(&self) -> &[F]

The unique classes discovered during training.

pub fn predict_proba(&self, x: &Array2<F>) -> Result<Array2<F>>

Predict class probabilities for each sample.

For binary classification, returns shape (n_samples, 2) with columns [P(class_0), P(class_1)]. For multi-class, returns (n_samples, n_classes) using softmax over the OVR log-odds.

pub fn feature_importances(&self) -> Array1<F>

Feature importances averaged across all tree sets, normalized to sum to 1.

Each tree’s importances are accumulated and weighted by the number of boosting rounds.
