Abstract:Three models of artificial neural network were established to predict the thermal state indexes (RDI, RI, RSI) of iron ore pellets. Initial input factors of the networks were found according to the pellet mine theory. Then sensitivity analysis was used to quantify the importance of each input variable and reduce the networks' input dimensionality. At last, minimum sets of input factors of networks were found to improve the accuracy of network prediction. Simulation results show that the prediction models meet … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
