“…Twenty training approaches have been carried out, using two transfer functions such as hyperbolic tangent sigmoid (tansig) and logarithmic sigmoid (logsig) and ten different neuron numbers (4,5,6,7,8,9,10,15,20,25) in the hidden layer, to determine the structure by which the best results could be obtained. Max-epoch value of 300 has been selected in training and the best prediction value of the optimum experiment result has been reached using the tansig function with eight neurons in the hidden layer.…”
