# Persistency
|
||
|
|
|
||
|
|
You can save trained models for future use. Persistency across requests achieved by saving and restoring serialized estimators into files.
|
||
|
|
|
||
|
|
### Example
|
||
|
|
|
||
|
|
```
|
||
|
|
use Phpml\Classification\KNearestNeighbors;
|
||
|
|
use Phpml\ModelManager;
|
||
|
|
|
||
|
|
$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);
|
||
|
|
|
||
|
|
$filepath = '/path/to/store/the/model';
|
||
|
|
$modelManager = new ModelManager();
|
||
|
|
$modelManager->saveToFile($classifier, $filepath);
|
||
|
|
|
||
|
|
$restoredClassifier = $modelManager->restoreFromFile($filepath);
|
||
|
|
$restoredClassifier->predict([3, 2]);
|
||
|
|
// return 'b'
|
||
|
|
```
