BOF End-Point Prediction Model Based on Nonlinear Homotopic BI Algorithm
Aiming at the defects of the neural network itself,such as low speed converging and liable to be trapped in local minimum,a homotopic BI neural network model is developed by combining the homotopy theory and the BI neural network model.While the end-point carbon content and temperature of molten steel is predicted by the new model,the precision of new model is improved accordingly.The hit rates are increased by about 5% and 10%,and the forecasting residuals have decreased 16.31% and 8.67% than the conventional ones respectively.Also,the calculation time of the new model is10% shorter than BI model.
