Neural networks are composed of simple elements operating in parallel. These
elements are inspired by biological nervous systems. As in nature, the network
function is determined largely by the connections between elements. We can
train a neural network to perform a particular function by adjusting the values
of the connections (weights) between elements.
Commonly neural networks are adjusted, or trained, so that a particular input
leads to a specific target output. Such a situation is shown below.
