An artificial neural network is a mathematical or
computational model for information processing based on a
connectionist approach to computation.
There is no precise agreed definition amongst researchers as
to what a neural network is, but most would agree that it
involves a network of relatively simple processing elements,
where the global behaviour is determined by the connections
between the processing elements and element parameters.
The original inspiration for the technique was from
examination of bioelectrical networks in the brain formed by
neurons and their synapses. In a neural network model,
simple nodes (or "neurons", or "units") are connected
together to form a network of nodes — hence the term "neural
network".
