PHP-ML - Machine Learning library for PHP

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

This version of PHP-ML requires PHP 5.6

The code is transpiled using (https://github.com/spatie/7to5)

• Why do this? This package is amazing and I believe there is no reason why should not be available also for php 5.6
• How to install
• Add to composer as:

"php-ai/php-ml": "dev-master"

• Add Repository of type VCS in your composer:

  "repositories": [
    {
      "type": "vcs",
      "url": "https://github.com/atompulse/php-ml-56",
      "no-api": true
    }
  ],

---

Simple example of classification:

require_once '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'
