MnistDataset

Helper class that loads data from MNIST dataset: http://yann.lecun.com/exdb/mnist/

The MNIST database of handwritten digits, available from this page, has a training set of 60,000 examples, and a test set of 10,000 examples. It is a subset of a larger set available from NIST. The digits have been size-normalized and centered in a fixed-size image. It is a good database for people who want to try learning techniques and pattern recognition methods on real-world data while spending minimal efforts on preprocessing and formatting.

Constructors Parameters

• $imagePath - (string) path to image file
• $labelPath - (string) path to label file

use Phpml\Dataset\MnistDataset;

$trainDataset = new MnistDataset('train-images-idx3-ubyte', 'train-labels-idx1-ubyte');

Samples and labels

To get samples or labels, you can use getters:

$dataset->getSamples();
$dataset->getTargets();
