ROC曲线的横轴是FPRate,纵轴是TPRate。设x=FPRate, y=TPRate,设y=x(即表示模型预测正确与预测错误的概率相等),就是下面这个样子,这时候AUC=0.5, 此时类似于一个抛均匀硬币的模型(这种模型结果应该是最差的结果,因为相当于完全随机,毫无预测能力,因为但凡正确率<0.5,错误率>0.5,将该模型结果反过来也能得到一个...
图3显示了DGNNMDA和七种竞争方法的ROC曲线和AUC值,从中可以发现作者的方法获得了最高的AUC值0.9255,其次是GANLDA。此外,表2列出了其他性能指标,并验证了方法在AUC、AUPR、准确率、召回率和F1分数等指标方面优于其他方法,除了精确率指标。由于miRNA与药物敏感性之间的关联相对稀疏,竞争方法无法很好地拟合数据或遭受过...

miRNA qPCR 验证:对 PPC 组关键 miRNA 进行 qPCR 验证及 ROC 曲线分析,hsa - miR - 1976、hsa - miR - 4685 - 3p、hsa - miR - 143 - 3p 和 hsa - miR - 128 - 1 - 5p 的 AUC 值均大于 0.7,表明它们在高原 Psycho - CVD 发病机制中起重要作用。 富集分析:PPC 组中,KEGG 富集分析发现 PI3K...
Receiver operating characteristic (ROC)曲线分析肝癌患者与正常人群之间该组microRNA的表达差异,AUC值为0.941。 原文:Jian Zhou, Lei Yu, Xue Gao, Jie Hu, Jiping Wang, Zhi Dai, Jie-Fei Wang, Zhiyong Zhang, Shaohua Lu, Xiaowu Huang, Zheng Wang, Shuangjian Qiu, Xiaoying Wang, Guohuan Yang, Huich...
Receiver operating characteristics (ROC) curves, area under ROC curves (AUC) and calibration plot were plotted to evaluate the model performance and clinical application. Results A total of 944 radiomics features were extracted based on volume of interest in CT images. For the prediction of micro...
This was alongside Gleason scores greater than 7 in 54% of the patients, and clinical stages of T1/T2 in 89% and T3 in 9%. The baseline clinical model produced a result of 0.73 for the area under the curve of the receiver operating characteristic (AUC). The integration of radiomic ...
4, the AUC was 0.96 (95% CI: 0.884–1.00; p < 0.001). Figure 4 ROC analysis for the multivariate logistic regression model predicting idiopathic DCMSEV patients. The mean AUC for the averaged ROC curves are presented. The data are presented as the AUC and 95% CI and corresponding ...
联合miR-27a、miR-320诊断PCOS 的AUC 为0.917（95%CI：0.869，0.964），高于单独诊断的0.708（95%CI：0.637，0.779）和0.676（95%CI：0.602，0.750）。结论PCOS患者血清miR-27a表达上调，miR-320表达下调，miR-27a高表达、miR-320低表达与PCOS易感和胰岛素抵抗有关，可作为PCOS诊断指标。关键词：多囊...
从结果上说明，关于具体的详细原理，怎么挨个算TP、FP、FN、TN、micro-f1、macro-f1、ROC、AUC等指标...
