<p>If you're too lazy to dive into programming neural networks but want to grasp the essence and get hands-on experience, there's a cool sandbox from Tensorflow.</p>
<p>The main task of your neural network is to distinguish between blue and orange dots (for example, you can imagine these as good and rotten apples).</p>
<p>By managing the structure (the number of layers, neurons in each layer) and other parameters, you should train it to successfully tackle the task.</p>
