| Abstract: | By combining global optimization of the Immune Genetic Algorithm(IGA) with local optimization of the BP neural network,the calculation accuracy and convergence rate of the BP neural network are improved,and the model of IGA-BP networks is applied to predicting the silicon content of blast furnace hot metal.The numerical results of the model show that the prediction precision is improved and the iteration number is much less than that by the normal BP network model.The test and simulation results are satisfactory. |
