Fresh approach to Machine Learning in PHP. Algorithms, Cross Validation, Neural Network, Preprocessing, Feature Extraction and much more in one library.

PHP-ML requires PHP >= 7.2.

Simple example of classification:

require_once __DIR__ . '/vendor/autoload.php';
use Phpml\Classification\KNearestNeighbors;
$samples = [[1, 3], [1, 4], [2, 4], [3, 1], [4, 1], [4, 2]];
$labels = ['a', 'a', 'a', 'b', 'b', 'b'];
$classifier = new KNearestNeighbors();
$classifier->train($samples, $labels);
echo $classifier->predict([3, 2]);
// return 'b'

To find out how to use PHP-ML follow Documentation.

Currently this library is in the process of being developed, but You can install it with Composer:

composer require php-ai/php-ml

Example scripts are available in a separate repository php-ai/php-ml-examples.

Public datasets are available in a separate repository php-ai/php-ml-datasets.
