摘要 通过回顾机器学习中的C4.5决策树、随机森林、支持向量机、BP神经网络算法的原理与在中医辨证研究中所取得的成果，创新设计出一种复合结构的智能化辨证选方模型，并对模型进行了实现与测试。结果表明该模型输出结果的准确性高于仅使用单一算法建立的辨证选方模型，这为进一步与“方-證要素对应”的组方原则相结合，建立适用于复杂病机的临床诊疗辅助系统奠定了基础。

    Abstract Through a review of the C4.5 Decision Tree， Random Forest， Support Vector Machine and BP Neural Network algorithm and the obtained in the study of TCM syndrome differentiation， a compound structure of intelligent syndrome differentiation and formula selection model was designed. The model was implemented and tested. Results showed that the accuracy of the corresponding results was higher than that of the single algorithm ......
