Struct linfa_elasticnet::ElasticNet [−][src]
Elastic Net model
This struct contains the parameters of a fitted elastic net model. This includes the seperating hyperplane, (optionally) intercept, duality gaps and the number of step needed in the computation.
Implementations
impl<F: Float> ElasticNet<F>
[src]
View the fitted parameters and make predictions with a fitted elastic net model
pub fn parameters(&self) -> &Array1<F>
[src]
Get the fitted parameters
pub fn intercept(&self) -> F
[src]
Get the fitted intercept, 0. if no intercept was fitted
pub fn n_steps(&self) -> u32
[src]
Get the number of steps taken in optimization algorithm
pub fn duality_gap(&self) -> F
[src]
Get the duality gap at the end of the optimization algorithm
pub fn z_score(&self) -> Result<Array1<F>>
[src]
Calculate the Z score
pub fn confidence_95th(&self) -> Result<Array1<(F, F)>>
[src]
Calculate the confidence level
impl<F: Float> ElasticNet<F>
[src]
pub fn params() -> ElasticNetParams<F>
[src]
Create a default elastic net model
By default, an intercept will be fitted. To disable fitting an
intercept, call .with_intercept(false)
before calling .fit()
.
To additionally normalize the feature matrix before fitting, call
fit_intercept_and_normalize()
before calling fit()
. The feature
matrix will not be normalized by default.
pub fn ridge() -> ElasticNetParams<F>
[src]
Create a ridge model
pub fn lasso() -> ElasticNetParams<F>
[src]
Create a lasso model

[src]
fn predict_ref<'a>(&'a self, x: &ArrayBase<D, Ix2>) -> Array1<F>
[src]

,
predict
returns the target variable according to elastic net
learned from the training data distribution.
