Deep learning promises to make computers far better at tasks like facial recognition, image understanding and machine translation. Our October puzzle asked you to play with simple artificial neural networks to explore the phenomenon of deep learning and gain some insight into how it has achieved such spectacular successes in the field of artificial intelligence. We're going to create a simple network that converts binary numbers to decimal numbers. Imagine a network with just two layers: an input layer consisting of three units and an output layer with seven units. Each unit in the first layer connects to each unit in the second, as shown in the figure below.
