| 摘 要： | 大多数机器学习算法能得到较好的分类效果，但模型却无法解释；而随机森林等模型有良好的可解释性，却无法处理中医数据中兼证的情况。本文利用极值随机森林算法对慢性胃炎中医数据进行证候分类研究，其中决策树的叶节点能输出多个标签，通过加权机制综合分量来处理兼证问题。与已有多标记学习算法和C4.5、CART等基于决策树的算法进行比较，实验结果表明，极值随机森林算法无论在6个证型的分类准确率上，还是在多标记评价指标上都具有更好的效果，而且模型中得到的规则基本符合中医理论。

| Abstract: | Syndrome differentiation and treatment,which is the essence of traditional Chinese medicine (TCM),contain abundant rules.The majority of machine learning algorithms can obtain good classification accuracy,but these models are difficult to be explained.The models established by random forests have great interpretability,while these models cannot deal with multi-syndrome that patients may simultaneously have more than one syndrome in TCM.In this paper,syndrome classification for Chronic Gastritis (CG) is researched by using extremely randomized forest (ERF) algorithm,and compared with state-of-the-art multi-label algorithms and the tree-based algorithms (such as C4.5,CART).The experimental results show that ERF algorithm has better performance than other algorithms in the classification accuracy of every label and the six evaluation metrics of multi-label learning.The rules obtained in the model are basically in accord with TCM theory. |
