Struct GridSearch 

pub struct GridSearch {
    pub points_per_param: usize,
    /* private fields */
}

Grid search optimizer.

Exhaustively searches all combinations of parameter values. Best for small, discrete search spaces.

Example

use aprender::automl::{GridSearch, SearchSpace, SearchStrategy};
use aprender::automl::params::RandomForestParam as RF;

let space = SearchSpace::new()
    .add(RF::NEstimators, 10..100)
    .add(RF::MaxDepth, 2..10);

let mut search = GridSearch::new(5); // 5 points per continuous param
let trials = search.suggest(&space, 100);

// Grid of 5x5 = 25 configurations
assert!(trials.len() <= 25);

Fields

points_per_param: usize

Number of grid points per continuous parameter.

Implementations

impl GridSearch

pub fn new(points_per_param: usize) -> Self

Create grid search with specified granularity.

Trait Implementations

impl Clone for GridSearch

fn clone(&self) -> GridSearch

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GridSearch

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

Formats the value using the given formatter.

impl<P: ParamKey> SearchStrategy<P> for GridSearch

fn suggest(&mut self, space: &SearchSpace<P>, n: usize) -> Vec<Trial<P>>

Generate candidate configurations to evaluate.

fn update(&mut self, _results: &[TrialResult<P>])

Update strategy with evaluation results (for adaptive methods).
