摘要:The accurate prediction to the gas amount consumed by hot blast furnace (HBF) is one of the important tasks for the gas scheduling in steel industry. In this study, a prediction model based on least support vector machine (LSSVM) is developed by considering the characteristics of gas consumption flow and the on-line requirement in practice. Since it is difficult to determine the optimal parameters of the model by some common methods, a fast cross-validation (FCV) method combined with the gradient based optimal algorithm is proposed in this paper to realize the on-line optimization to the hyper parameters. The simulation results with the practical blast furnace gas consumption data of HBF in Shanghai Baosteel show the modeling method is time-economized, while the on-line prediction performance are superior to the standard SVM and the neural network.
