数据集:乳腺癌数据集(from sklearn.datasets import load_breast_cancer)。 (1)将样本集划分为70%的训练集,30%作为测试集,分别用逻辑回归算法和KNN算法(需要先对数据进行标准化)建模(不指定参数),输出其测试结果的混淆矩阵,计算其准确率、查全率和假正率。 (2)利用搜索网格,分别确定逻辑回归及KNN模型的最优参数。
1:首先需要获得Breast Cancer dataset数据集,在kaggle上获取该数据集需要FQ,该数据解压后为csv格式 2:使用pandas.read_csv()来读入数据,并查看数据的前五项条目 3:查看数据的具体信息,一共有32列(其中第二列diagnosis为标签,其他列为特征),569行,发现有一列为空列你并将其删除 4:将数据调整成sklearn能够传入的...

First, the breast cancer dataset had numerous missing values, and the use of simulations to fill in these missing data may have led to deviations from real-world situations. Second, the study involved three machine learning models, and the predictive accuracy of the XGB model was only moderate...
