“…According to the difference of their functions, artificial neural networks can be divided into feedback network and feedforward network [6]. Feedback neural network generally includes input layer, hidden layer, undertaking layer and output layer [11] [16,17], automatic control [18,19], market analysis [20,21], chemical industry [22][23][24], game theory [25], medicine diagnosis [26][27][28], signal processing [29][30][31], troubleshooting [32,33], machine Learning [34][35][36] and other fields. The construction of artificial neural networks is realized by the simulation of human brain function, rather than by complex mathematical models.…”
