Dr Robert Hecht-Nielsen. He defines a neural network as: “…a computing system made up of several simple, highly interconnected processing elements, which process information by their dynamic state response to external inputs. ANN are processing units/devices/nodes which are modelled, albeit loosely, on the mammalian cerebral cortex. Obviously, the scale, now, bears little relationship with the mammalian brain, numbering in the hundreds rather than in the billions. ANN based computing is also known as neurocomputing. These biologically inspired methods of computing are likely to be the next big advancement in the computing industry. ANNs have the potential to be applied across numerous areas and fields.
