Struct StackingRegressor

Source

pub struct StackingRegressor<F: Float> { /* private fields */ }

Expand description

Stacking regressor.

Base estimators produce predictions, which become features for a meta-estimator that learns to combine them. During fitting, base model predictions are generated via cross-validation to avoid overfitting.

Implementations§

Source §

impl<F: Float> StackingRegressor<F>

Source

pub fn new<M>(meta_estimator: M) -> Self
where M: Fit<F> + Send + Sync + 'static, M::Fitted: Predict<F> + Send + Sync + 'static,

Create a new StackingRegressor with the given meta-estimator.

Source

pub fn push<T>(self, name: impl Into<String>, estimator: T) -> Self
where T: Fit<F> + Send + Sync + 'static, T::Fitted: Predict<F> + Send + Sync + 'static,

Add a base estimator.

Source

pub fn with_cv_folds(self, cv_folds: usize) -> Self

Set the number of CV folds for generating meta-features. Default: 5.
