Struct Ridge 

pub struct Ridge { /* private fields */ }

Ridge regression model.

Implementations

impl Ridge

pub fn new(n_x: u64, n_y: u64, beta: f64) -> Self

Create a new Ridge regression model. ‘n_x’ is the number of input variables and ‘n_y’ is the number of output variables. ‘beta’ is the regularization parameter.

examples/ridge.rs (line 9)

fn main() {
    let x = na::DVector::from_vec(vec![1.0, 2.0, 3.0, 4.0]);
    let d = na::DVector::from_vec(vec![5.0, 6.0]);

    let mut ridge = Ridge::new(4, 2, 0.1);
    ridge.set_data(&x, &d);
    let weight = ridge.fit();

    println!("{}", ridge);
    println!("Weight:\n{}", weight);
}

pub fn set_data(&mut self, x: &DVector<f64>, d: &DVector<f64>)

Update the internal state of the Ridge regression model. ‘x’ is the input vector (explanatory variable) and ‘d’ is the output vector (response variable).

    let weight = ridge.fit();

    println!("{}", ridge);
    println!("Weight:\n{}", weight);
}

pub fn fit(&self) -> DMatrix<f64>

Fit the Ridge regression model and return the weight matrix.
