Struct LossLandscape 

pub struct LossLandscape {
    pub values: Vec<f32>,
    pub width: usize,
    pub height: usize,
    pub x_range: (f32, f32),
    pub y_range: (f32, f32),
}

A 2D grid of loss values sampled along two parameter directions.

Fields

values: Vec<f32>

Loss values in row-major order (height x width).

width: usize

height: usize

x_range: (f32, f32)

Range of the x-axis parameter.

y_range: (f32, f32)

Range of the y-axis parameter.

Implementations

impl LossLandscape

pub fn new( width: usize, height: usize, x_range: (f32, f32), y_range: (f32, f32), ) -> Self

pub fn set(&mut self, x: usize, y: usize, val: f32)

pub fn get(&self, x: usize, y: usize) -> f32

pub fn min_loss(&self) -> f32

pub fn max_loss(&self) -> f32

pub fn generate_synthetic(width: usize, height: usize) -> Self

Generate a synthetic loss landscape (for testing/demo). Uses a sum-of-Gaussians to create a bowl-like landscape.

fn clone(&self) -> LossLandscape

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LossLandscape

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