使用MATLAB神经网络工具箱创建了前馈型三层BP神经网络。在这一部分，本文还介绍了如何实现VB与MATLAB的集成，并编写了程序。该程序可实现对新产品的模拟评价，并得到预测结果。这种模拟评价可大大提高食品配料研发的效率。-Use MATLAB toolbox created feedforward neural network type three BP neural network. In this part, this paper also introduces how to realize the integration of the VB and MATLAB, and write the program. The program can be used for simulation of the new product evaluation, and get the forecasting results. The model evaluation can greatly improve the efficiency of research and development of food ingredients.
