Description Author

This package can assemble and process layerless neural networks.

It can assemble different types of neurons with initial values and connect them using synapses.

It can also use the back propagate algorithm to adjust neuron weights by setting target values on the output neurons and recheck the values again.

Layerless

Layerless is the new foundation of the legendary mind neural network project

Installation

composer require devtronic/layerless

Usage

<?php

// Import the SinusActivator as Activator
use Devtronic\Layerless\Activator\SinusActivator as Activator;
use Devtronic\Layerless\BiasNeuron;
use Devtronic\Layerless\InputNeuron;
use Devtronic\Layerless\Neuron;
use Devtronic\Layerless\Synapse;

// Load Composer autoload
require_once __DIR__ . '/vendor/autoload.php';

// Create the activator
$activator = new Activator();

// Create 2 Input Neurons and 1 Bias Neuron
$inputA = new InputNeuron(1);
$inputB = new InputNeuron(0);
$bias = new BiasNeuron(1);

// Create 1 Output Neuron
$output = new Neuron($activator);

// Connect the neurons

new Synapse(0.90, $inputA, $output);
new Synapse(0.23, $inputB, $output);
new Synapse(0.50, $bias, $output);

// Activate the neurons
$inputA->activate();
$inputB->activate();
$output->activate();

echo $output->getOutput() . PHP_EOL; // 0.98545

// Back propagate
$target = 0;
$output->calculateDelta($target);
$inputA->calculateDelta();
$inputB->calculateDelta();

$learningRate = 0.2;
$output->updateWeights($learningRate);
$inputA->updateWeights($learningRate);
$inputB->updateWeights($learningRate);

// Re-Check
$inputA->activate();
$inputB->activate();
$output->activate();

echo $output->getOutput() . PHP_EOL; // 0.92545
