Abstract: Objective To discuss some problems about the application of BP network to the optimization of pharmaceutical prescription. Method The problems concerned included some basic conceptions of BP network, the collection and sorting of sample data, the definition of the I/O variable and the pretreatment of the sample data, the principle of choosing the number of the hidden layer and note, the evaluation of the neural network training and the generalization capability of the modular, the effect of the weight of network initialized connecting and so on. Results A general method and procedures of the prescription optimization was proposed with an example. Conclusions A general guidance on how to establish an optimal neural network modular for prescription optimization using BP network was provided.
