Struct rusty_machine::learning::optim::grad_desc::GradientDesc

pub struct GradientDesc { /* private fields */ }

Batch Gradient Descent algorithm

Implementations

impl GradientDesc

pub fn new(alpha: f64, iters: usize) -> GradientDesc

Construct a gradient descent algorithm.

Requires the step size and iteration count to be specified.

Examples

use rusty_machine::learning::optim::grad_desc::GradientDesc;

let gd = GradientDesc::new(0.3, 10000);

Trait Implementations

impl Clone for GradientDesc

fn clone(&self) -> GradientDesc

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for GradientDesc

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

Formats the value using the given formatter.

impl Default for GradientDesc

The default gradient descent algorithm.

The defaults are:

• alpha = 0.3
• iters = 100

fn default() -> GradientDesc

Returns the “default value” for a type.

impl<M: Optimizable> OptimAlgorithm<M> for GradientDesc

fn optimize(
    &self,
    model: &M,
    start: &[f64],
    inputs: &M::Inputs,
    targets: &M::Targets
) -> Vec<f64>

Return the optimized parameter using gradient optimization.
