摘 要:目的运用集成学习中的XGBoost算法探索构建中药寒热药性识别模型,采用SHAP进一步探索中药寒热特征标记与寒热药性识别结果的关系。方法利用61味中药的紫外光谱数据集,运用集成学习中的XGBoost算法,构建中药寒热药性识别模型,通过稳定性评价和外推评价等方式评估模型的性能,采用SHAP对中药寒热特征标记进行可视化。结果模型评价方面,在稳定性比较中,本文模型在单溶剂下的ACC和AUC分别为0.852、0.865,多溶剂下的ACC为0.770;在外推比较中,本文模型在单溶剂下的ACC和AUC分别为0.810、0.828,多溶剂下的ACC为0.786;可视化方面,寒性中药在紫外波长400和267 nm的吸收度具有相似性,而热性中药在紫外波长400、299和301 nm的吸收度具有相似性。结论与经典模型相比,本文模型对中药寒热药性具有更好的识别能力。具有相似的紫外光谱的中药,其药性同样具有相似性,初步证明了物质成分相似的中药具有相似的药性。Objective The XGBoost algorithm in ensemble learning was used to explore the establishment of the identification model of cold-hot nature of Chinese herbal medicines,and the relationship between cold-hot characteristic markers and the identification results of cold-hot nature of Chinese herbal medicines was further explored by SHAP.Methods Using the ultraviolet spectrum data set of 61 Chinese herbal medicines,the XGBoost algorithm in ensemble learning was used to construct the identification model of cold-hot nature of Chinese herbal medicines,the performance of the model was evaluated by stability evaluation and extrapolation evaluation,and the cold-hot characteristic markers of Chinese herbal medicines were visualized by SHAP.Results In terms of model evaluation,in the stability comparison,the ACC and AUC of this model in single solvent were 0.852 and 0.865 respectively;The ACC under multi-solvent was 0.770.In the extrapolation comparison,the ACC and AUC of this model in single solvent were 0.810 and 0.828 respectively;The ACC under multi-solvent was 0.786.In terms of visualization,the absorption of cold Chinese herbal medicines at UV wavelengths of 400 and 267 nm was similar,while that of hot Chinese herbal medicines at UV wavelengths of 400,299 and 301 nm was similar.Conclusion Compared with the classical model,the model in this paper has better identification ability for cold-hot nature of Chinese herbal medicines.Chinese herbal medicines with similar UV spectrum have similar nature,it is preliminarily proved that Chinese herbal medicines with similar material components have similar nature.
