Struct LinearSVR 

pub struct LinearSVR<F> {
    pub c: F,
    pub epsilon: F,
    pub max_iter: usize,
    pub tol: F,
    pub loss: LinearSVRLoss,
}

Linear Support Vector Regressor (primal formulation).

Solves the L2-regularized epsilon-insensitive or squared epsilon-insensitive loss via coordinate descent in the primal.

Type Parameters

• F: The floating-point type (f32 or f64).

Fields

c: F

Inverse regularization strength.

epsilon: F

Width of the epsilon-insensitive tube.

max_iter: usize

Maximum number of coordinate descent iterations.

tol: F

Convergence tolerance on the change in weight vector.

loss: LinearSVRLoss

Loss function to use.

pub fn with_c(self, c: F) -> Self

Set the regularization parameter C.

pub fn with_epsilon(self, epsilon: F) -> Self

Set the epsilon tube width.

pub fn with_max_iter(self, max_iter: usize) -> Self

Set the maximum number of iterations.

pub fn with_tol(self, tol: F) -> Self
