数据集分割train和test程序
`train_test_split`是一个用于将数据集分成训练集和测试集的函数。函数的输入通常是数据集和与其相关联的标签集。函数中的参数`test_size`用于指定测试集所占的比例,`random_state`用于设置随机数种子以获得可重复的分割结果。以下是`train_test_split`函数在给定参数下的例子:[^1][^2]
```python
from sklearn.model_selection import train_test_split
# 假设data和test都为特征集,且test是目标变量
X_train, X_test, y_train, y_test = train_test_split(data, test, test_size=0.2, random_state=6)
```
