, _(*1)

A dead simple neural network. For educational purposes only. Ported from Java into PHP. Originally written in Java from Brotcrunsher a German youtuber who makes tutorials about computer science., _(*2)

Note: The project is still under construction and can change at any time, _(*3)

Installation

$ composer require patrickschur/neural-network

Examples

Creating a simple single-layer perceptron network with four inputs and one output neuron., _(*4)

// Creates the neural network
$nn = new NeuralNetwork();

// Creates four input neurons
$i1 = $nn->createNewInput();
$i2 = $nn->createNewInput();
$i3 = $nn->createNewInput();
$i4 = $nn->createNewInput();

// Sets the input for each input neuron
$i1->setValue(1);
$i2->setValue(2);
$i3->setValue(3);
$i4->setValue(4);

// Creates the output neuron
$o1 = $nn->createNewOutput(new Identity());

// Sets the weights and connect each input to the output neuron
$nn->createFullMesh(0, 0, 0, 0);

echo $o1->getValue(); // Output 0
