README
This is a PHP package for building neural networks in PHP, if theirs enough interest I will adapt it into a PHP C module providing very quick training on the CPU and GPU.
Example Usage
$total_hidden_neurons = 4;
$total_hidden_layers = 2;
$learning_rate = 0.1;
$epochs = 500000;
$total_input_neurons = 2;
$total_output_neurons = 1;
// You can use either "relu" or "sigmoid" for the activation function
$network = new NeuralNetwork($total_input_neurons, $total_output_neurons, $learning_rate, $epochs, $total_hidden_neurons, $total_hidden_layers, 'relu');
// Train the network on one page at a time, useful for large datasets
// where you can simply load from the database.
$network->trainNetworkBatch(4, function ($page, $total_per_page, &$input, &$output) {
switch ($page) {
case 0:
$input = [
[0, 0],
[1, 0],
[0, 1],
];
$output = [
[0], [1], [1]
];
break;
case 1:
$input = [
[1, 1]
];
$output = [
[0]
];
break;
default:
echo 'out of bounds';
exit;
break;
}
}, 3);
$network->forwardPass([1, 0], $output);
print_r($output);
