# AlizeLib

Calculate the averages, total & best of labelled data, import and export the model for later use.

## Installation

The library can be installed using ncc:

```bash
ncc install -p "nosial/libs.alize=latest@n64"
```

or by adding the following to your project.json file under

the `build.dependencies` section:

```json
{
  "name": "net.nosial.alizelib",
  "version": "latest",
  "source_type": "remote",
  "source": "nosial/libs.alize=latest@n64"
}
```

If you don't have the n64 source configured you can add it

by running the following command:

```bash
ncc source add --name n64 --type gitlab --host git.n64.cc
```

## Compiling from source

The library can be compiled from source using ncc:

```bash
ncc build --config release
```

or by running the following command:

```bash
make release
```

## Usage

```php
// ncc
require 'ncc';
import('net.nosial.alizelib');

// Create a new model
$size = 100; // The size of the model
$model = new \AlizeLib\GeneralizationModel($size);

// We are intentionally adding more data to the model
// than the model can hold, this is to demonstrate
// how old data is removed from the model.

// Add random high float values to the model under label "en" x 150 times
for($i = 0; $i < 150; $i++)
{
    $model->add("en", random_float(0.5, 1));
}

// Add random low float values to the model under label "zh" x 150 times
for($i = 0; $i < 150; $i++)
{
    $model->add("zh", random_float(0, 0.5));
}

// Add random very low float values to the model under label "fr" x 150 times
for($i = 0; $i < 150; $i++)
{
    $model->add("fr", random_float(0, 0.1));
}

// Add random very high float values to the model under label "de" x 150 times
for($i = 0; $i < 150; $i++)
{
    $model->add("de", random_float(0.9, 1));
}

// Best label should be "de" or second best "en"
var_dump($model->calculateBestLabels());
```
