Neural networks, specifically known as artificial neural networks (ANNs), were developed by the inventor of one of the first neurocomputers, Dr. Robert Hecht-Nielsen. He defines a neural network as follows:

“…a computing system made up of a number of simple, highly interconnected processing elements, which process information by their dynamic state response to external inputs.”

Customarily, neutral networks are arranged in multiple layers. The layers consist of several interconnected nodes containing an activation function. The input layer, ...
