|
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 >= 7.1.
|
|
|
|
Simple example of classification:
|
|
```php
|
|
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);
|
|
|
|
$classifier->predict([3, 2]);
|
|
// return 'b'
|
|
```
|
|
|
|
## Documentation
|
|
|
|
To find out how to use PHP-ML follow [Documentation](http://php-ml.readthedocs.org/).
|
|
|
|
## Installation
|
|
|
|
Currently this library is in the process of developing, but You can install it with Composer:
|
|
|
|
```
|
|
composer require php-ai/php-ml
|
|
```
|
|
|
|
## Examples
|
|
|
|
Example scripts are available in a separate repository [php-ai/php-ml-examples](https://github.com/php-ai/php-ml-examples).
