      The modern view of artificial neural networks began in the 1940s with the work of Warren McCulloch and Walter Pitts [13], who showed that networks of artificial neurons could, in principle, compute any arithmetic or logical function. Their work is often acknowledged as the origin of the artificial neural network field.

      Research in the field of neural networks has been attracting increasing attention in recent years. Since 1943, when Warren McCulloch and Walter Pitts presented the first model of artificial neurons, new and more sophisticated proposals have been made from decade to decade[11, 13,14]. Mathematical analysis has solved some of the

      • In 1943, Warren McCulloch and Walter Pitts introduced one of the first artificial neurons. • The main feature of their neuron model is that a weighted sum of input signals is compared to a threshold to determine the neuron output. • When the sum is greater than or equal to the threshold, the output is 1. When the sum is less than

      The simplest artificial neural network is the “perceptron”, composed by a single artificial neuron. It was introduced by Frank Rosenblatt (1958) [7], based on research of Warren McCulloch and Walter Pitts (1943) [8]. The perceptron computes the weighted sum of its n input values xi: y = w•x+b = Σwi•xi + b; i = 1÷n (1)
