本文简要介绍python语言中 sklearn.datasets.load_breast_cancer 的用法。 用法: sklearn.datasets.load_breast_cancer(*, return_X_y=False, as_frame=False) 加载并返回乳腺癌威斯康星数据集(分类)。 乳腺癌数据集是一个经典且非常简单的二元分类数据集。 Classes 2 每班样本 212(男),357(乙) 样品总数 569...
步骤1:数据加载 首先,我们需要导入load_breast_cancer函数来加载乳腺癌数据集。这个函数可以从sklearn库中的datasets模块中获取。 fromsklearn.datasetsimportload_breast_cancer# 使用load_breast_cancer函数加载乳腺癌数据集data=load_breast_cancer() 1. 2. 3. 4. 步骤2:数据预处理 在进行模型训练之前,我们需要对...

We found no association between dietary GL [multivariable-adjusted relative risk (RR), 1.01; confidence interval (CI), 0.76–1.35, comparing extreme quintiles; P for trend = 0.96] or overall GI (corresponding RR, 1.03; CI, 0.84–1.28; P for trend = 0.66) and breast cancer risk in the ...
