Parameters estimation of sinter ore match poor information combined bootstrap method, grey analysis and artificial neural networks models
摘要
Abstract
An iron ore sinter evaluating function based on back propagation neural networks (BP) model was adopted to express and analyze complex sinter parameters information. The basic BP model consists of 13 input nodes, 27 hidden nodes and 2 output nodes. The input parameters included essential chemical composition parameters, quantity of conglutination particle and nucleolus particle of mixed ores; the output parameters consisted of sintering velocity and tumbler strength; and the hidden node was obtained through BP modeling with 100 groups of data for training and 50 groups of data for testing. Static information of experiments data was processed by Bootstrap method and change tendency information of process data was analyzed by grey analysis method. A kind of parameter estimation scheme was proposed based on BP model and statistics probability calculation. Sinter general and dynamic information was synthesized by the neural networks models, and estimation values of parameters within the ore evaluating functions were deduced by Monte Carlo simulation integrated statistics probability calculation. The estimation and simulation results provide an effective analysis means for sinter poor information.关键词
