摘　　要：病理学检查是医生确定肿瘤是否发生癌变的“金标准”,但由于肺癌病理组织具有多种亚型,医生需要反复大量阅片才能最终给出医学诊断,不仅耗时且易出错。因此,本文借助深度学习进行肺癌病理组织亚型分类研究。通过对数据库数据进行预处理,找出特征值,使用不同层深的ResNet算法构建肺癌病理图像类别分类器,模型参数调整到最优后,对比训练ResNet18、ResNet34、ResNet50三个不同层次网络模型,分析模型的accuracy、recall、F1-score和算术平均值等评价指标,其中ResNet34模型指标最佳,对肺癌病理图像的分类效果最好。Pathological examination is the“gold standard”for doctors to determine whether a tumor has undergone cancerous transformation.However,due to the multiple subtypes of lung cancer pathological tissue,doctors need to repeatedly review a large number of films in order to finally give a medical diagnosis,which is not only time-consuming but also prone to errors.Therefore,this article utilizes deep learning to study the subtype classification of lung cancer pathological tissues.By preprocessing the database data,finding the feature values,and using different layers of ResNet algorithms to construct lung cancer pathology image classification models,after adjusting the model parameters to the optimal value,we compared the training results of three different network models:ResNet18,ResNet34,and ResNet50.We analyzed the accuracy,recall,F1-score,and arithmetic mean of the models,and found that the ResNet34 model had the best performance in terms of classification accuracy for lung cancer pathology images.
