PHP2xAI MNIST
=============

[](#php2xai-mnist)

MNIST classification exercise built on PHP2xAI. The project demonstrates dataset preprocessing in PHP, configuration of the computational graph, and training orchestration, while model training and inference are executed by the C++ runtime.

Installation
------------

[](#installation)

```
composer create-project antoniogweb/php2xai-mnist
```

Training
--------

[](#training)

Run the script from `src/`:

```
cd src
php train.php
```

What it does:

- Reads data from `src/DataLabelInt/Training/train.txt` and `src/DataLabelInt/Training/test.txt`.
- Trains the model and saves weights to `src/weights.json`.

PHP or C++ runtime:

- In `src/train.php` you will find `setRuntime("CPP")`: it uses the C++ runtime.
- To use the PHP runtime, replace it with `setRuntime("PHP")` or remove the call.

Batch size:

- The second argument of `StreamFileDataset` controls the batch size.
- In `src/train.php`, edit `new StreamFileDataset($path."/train.txt", 1024)` (and the validation dataset if needed).

Validation
----------

[](#validation)

Run the script from `src/`:

```
cd src
php validate.php
```

What it does:

- Loads the model from `src/model.json` and weights from `src/weights.json`.
- Computes accuracy and inference time on the test set.

PHP or C++ runtime:

- In `src/validate.php` you will find `setRuntime("CPP")`: it uses the C++ runtime.
- To use the PHP runtime, replace it with `setRuntime("PHP")` or remove the call.

Notes
-----

[](#notes)

- If you don't have `train.txt` and `test.txt` yet, generate them with `src/create_data_one_file.php` (requires images in `src/images/`).
