FANN neural network visualizations

, _(*1)

This component visualizes a FANN neural network using D3JS. The visualization shows nodes and their connections to eachother., _(*2)

Negative connections are shown in red, positive in green. The thickness and brightness of the connection is an indicator of it's strength., _(*3)

To create a visualization, you can configure a visitor that can visit the FANN topology:, _(*4)

use T4\Fann\Topology\Core\Topology;
use T4\Fann\Topology\Core\Neuron;
use T4\Fann\Topology\Visualization\D3J\D3JsNeuronVisitor;

$ann = ....; // your fann neural network resource
$topology = Topology::createFromFann($ann);

$visitor = D3JsNeuronVisitor();

// configure visitor here; here the node is given a name
$visitor->setNamingCallback(function(Neuron $n) {
    return 'node #' . $n;
});

// visit and get the collected data for configuring d3js
foreach ($topology->getNeurons() as $k => $neuron) {
    $neuron->accept($visitor);
}
$data = $visitor->getJsonData();
