Params#

Generate distributions of values to use in conjunction with Grid Search or other forms of model selection and/or cross validation.

Generate Params#

To generate a unique distribution of integer parameters:

public static ints(int $min, int $max, int $n = 10) : array

use Rubix\ML\Helpers\Params;

$ints = Params::ints(0, 100, 5);

print_r($ints);
Array
(
    [0] => 88
    [1] => 48
    [2] => 64
    [3] => 100
    [4] => 42
)

To generate a random distribution of floating point parameters:

public static floats(float $min, float $max, int $n = 10) : array

use Rubix\ML\Helpers\Params;

$floats = Params::floats(0, 100, 5);

print_r($floats);
Array
(
    [0] => 42.65728
    [1] => 66.74335
    [2] => 15.17243
    [3] => 71.92631
    [4] => 4.638863
)

To generate a uniformly spaced grid of parameters:

public static grid(float $min, float $max, int $n = 10) : array

use Rubix\ML\Helpers\Params;

$grid = Params::grid(0, 100, 5);

print_r($grid);
Array
(
    [0] => 0
    [1] => 25
    [2] => 50
    [3] => 75
    [4] => 100
)
