| Abstract: | Based on the application of BP network in the study of the dynamic rules of the confined water cones,several issues in development of BP network model including setting of monitor sample,normalized treatment of sample data,determination of the initial value of network weights and thresholds,and selection of training functions were investigated and practiced.The proposed methods and conclusions have general applicability,and provided reference methods for broad application of BP network. |
