Neural Networks

6.1 Perceptron Neural Network

A neural network is a model of reasoning that is inspired by biological neural networks, which is the central nervous system in an animal brain. The human brain consists of a huge number of interconnected nerve cells called neurons.

A neuron consists of a cell body, soma, a number of fibers called dendrites, and a single long fiber called the axon [1] (Figure 6.1).

The main function of dendrites is to receive messages from other neurons. Then, the signal travels to the main cell body, known as the soma. The signal leaves the soma and travels down the axon to the synapse. The message then moves through the axon to the other end of the neuron, then to the tips of the axon and then into the ...
