pub struct BaseLogisticRegressor { /* private fields */ }

Expand description

The Base Logistic Regression model.

This struct cannot be instantianated and is used internally only.

Trait Implementations

source

impl Debug for BaseLogisticRegressor

source

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

Formats the value using the given formatter. Read more

source

impl Optimizable for BaseLogisticRegressor

Computing the gradient of the underlying Logistic Regression model.

The gradient is given by

X^T(h(Xb) - y) / m

where h is the sigmoid function and b the underlying model parameters.

type Inputs = Matrix<f64>

The input data type to the model.

type Targets = Vector<f64>

The target data type to the model.

source

fn compute_grad(
 &self,
 params: &[f64],
 inputs: &Matrix<f64>,
 targets: &Vector<f64>
) -> (f64, Vec<f64>)

Compute the gradient for the model.
