A neural network consists of many simple elements called neurons which are grouped together in layers. A neuron has many inputs and a single output. Each input<br>has a coefficient, referred to as a weight, assigned to it. A neuron works in the<br>following way: inputs of the neuron are multiplied by the corresponding weights.<br>The product is then summed together and applied to a transfer function, to form<br>the output. This can be expressed using the following equation:<br>z ¼ f<br>Xn<br>i¼1<br>wixi þ d<br>!<br>ð1Þ<br>where z is the output from neuron; x1,x2, ....,xn are the input values; w1,w2, ....,wn are<br>the connection weights; d is the bias value; and f is the activation function.<br>يمكن تصور الشبكة العصبية الاصطناعية، ومجموعة من الخلايا العصبية المترابطة
