13 Neural Networks

Deep learning algorithms are based on building a network of connected computational elements. The fundamental unit of such networks is a small bundle of computation called an artificial neuron, though it’s often referred to simply as a neuron. The artificial neuron was inspired by human neurons, which are the nerve cells that make up our brain and central nervous system and are largely responsible for our cognitive abilities.

In this chapter, we see what artificial neurons look like and how to arrange them into networks. We then group them into layers, which create deep learning networks. We also look at various ways to ...
