Objective To set up diabetic nephropathy(DN) syndrome diagnostic model based on artificial neural network.Method Based on MATLAB7.0 environment,the BP neural network model of syndrome was set up using the improved conjugation gradient to study algorithms and the diagnosis performance of the BP neural network syndrome model was confirmed by triple and alternative examination.Result When using DN syndrome neural network model to predict DN syndrome,the average specificity of the single syndrome is 81.32%,the ...
