Artificial Neural Networks (ANNs) are geographically encouraged. Particularly, they borrow thoughts from the behavior in which the human intelligence works. The human intelligence is collected of special cells called neurons. Estimates of the quantity of neurons in a human intelligence cover a broad range (up to 150 billion), and there are more than a hundred dissimilar kinds of neurons, separated into groups called networks. Each network contains numerous thousand neurons that are highly interrelated. Thus, the brain can be viewed as a collection of neural networks.
