Struct FittedElasticNet 

pub struct FittedElasticNet<F> { /* private fields */ }

Fitted ElasticNet regression model.

Stores the learned (potentially sparse) coefficients and intercept. Implements Predict and HasCoefficients.

Implementations

impl<F: Float> FittedElasticNet<F>

pub fn intercept(&self) -> F

Returns the intercept (bias) term learned during fitting.

Trait Implementations

impl<F: Clone> Clone for FittedElasticNet<F>

fn clone(&self) -> FittedElasticNet<F>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<F: Debug> Debug for FittedElasticNet<F>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl FittedPipelineEstimator for FittedElasticNet<f64>

fn predict_pipeline(&self, x: &Array2<f64>) -> Result<Array1<f64>, FerroError>

Generate predictions via the pipeline interface.

Errors

Propagates any FerroError from predict.

impl<F: Float + Send + Sync + ScalarOperand + 'static> HasCoefficients<F> for FittedElasticNet<F>

fn coefficients(&self) -> &Array1<F>

Returns the learned coefficient vector.

fn intercept(&self) -> F

Returns the learned intercept term.

impl<F: Float + Send + Sync + ScalarOperand + 'static> Predict<ArrayBase<OwnedRepr<F>, Dim<[usize; 2]>>> for FittedElasticNet<F>

fn predict(&self, x: &Array2<F>) -> Result<Array1<F>, FerroError>

Predict target values for the given feature matrix.

Computes X @ coefficients + intercept.

Errors

Returns FerroError::ShapeMismatch if the number of features does not match the fitted model.

type Output = ArrayBase<OwnedRepr<F>, Dim<[usize; 1]>>

The prediction output type (e.g., ndarray::Array1<F> or ndarray::Array1<usize>).

type Error = FerroError

The error type returned by predict.
