The information technologies have been increasing exponentially following Moore’s law over the past decades. 1943 − It has been assumed that the concept of neural network started with the work of physiologist, Warren McCulloch, and mathematician, Walter Pitts, when in 1943 they modeled a simple neural network using electrical circuits in order to describe how neurons in the brain might work. The first step towards neural networks took place in 1943, when Warren McCulloch, a neurophysiologist, and a young mathematician, Walter Pitts, wrote a paper on how neurons might work. In 1943, McCulloch and Pitts created a model of the neuron that is still used today in an artificial neural network. We are now in one of its very big time.
