具有先验知识的前馈网络规划模型在海水腐蚀预测中的应用

A Feed Forward Network Mode with Prior Knowledge and Its Application to Forecasting Ocean-water Corrosion

摘要: 应用具有先验知识的前馈网络模型研究海水环境与材料(钢)腐蚀之间对应关系.结果表明该模型能够很好地揭示材料海水腐蚀规律,提高了预测准确度.

Abstract: The relatonship between material corrosion and ocean envirnmental factors is studied.A feed forward network incorporated with prior knowledge is used to model the mapping between the corrosion rate and the environmental factors.The calculation results show that the model can give a better prediction of the corrosion rate than those given by BP model.
