具有先驗知識的前饋網絡規劃模型在海水腐蝕預測中的應用

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

摘要: 應用具有先驗知識的前饋網絡模型研究海水環境與材料(鋼)腐蝕之間對應關系.結果表明該模型能夠很好地揭示材料海水腐蝕規律,提高了預測準確度.

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.
