用PHP中的神经网络确定形状

Question

所以，我在网上发现了这个类，这是一个用PHP编程的神经网络。您可以在此处找到它：http://pastebin.com/vVn4CABh

但是，我希望它根据输入执行操作。输入将是一个3 * 3网格，填充黑色或白色方块。方块创建'H'或'T'。所以，我为此创建了一些PHP代码。但我正在努力解决它。

在下面的代码中，我制作了一个T形黑色正方形，但它仍然认为它是T形。

$n = new NeuralNetwork(3, 4, 1);
$n->setVerbose(false);

//shape of T and H in 3*3 grid
$n->addTestData(array(1, 1, 1, 0, 1, 0, 0, 1, 0), array (0));
$n->addTestData(array(1, 0, 1, 1, 1, 1, 1, 0, 1), array (1));


$max = 3;


while (!($success = $n->train(1000, 0.01)) && $max -- > 0) {
    echo "Nothing found...<hr />";
}


if ($success) {
    $epochs = $n->getEpoch();
    echo "Success in $epochs training rounds!<hr />";
}

//T with one black square
$shape = $n->calculate(array(1,0,1,0,1,0,0,1,0));

$shape = $n->calculate(array(1,0,1,0,1,0,0,1,0));

print "output from neural network = (".implode(", ", $shape).")\n";
if ($shape > 0.5) {
    print "The shape is an H.";
} else {
    print "The shape is a T.";
}
