机器学习sklearn：处理缺失值

方案一、使用SimpleImputer

1、导入泰坦尼克号数据

import numpy as np
import pandas as pd
data = pd.read_csv(r"Narrativedata.csv", index_col=0)       # 设置0索引
data.head()
data.info()

可以看到有的数据有缺失：

2、实例化SimpleImputer，选择策略导入

Age = data.loc[:,"Age"].values.reshape(-1,1) #sklearn当中特征矩阵必须是二维，变为二维数组
Age[:20]
from sklearn.impute import SimpleImputer
# 实例化
imp_mean = SimpleImputer()      # 默认均值填补
imp_median = SimpleImputer(strategy="median")       # 用中位数填补
imp_0 = SimpleImputer(strategy="constant", fill_value=0)    # 用0来填补

# 填入属性中
imp_mean = imp_mean.fit_transform(Age)
imp_median = imp_median.fit_transform(Age)
imp_0 = imp_0.fit_transform(Age)

# 选择中位数填补data
data.loc[:, "Age"] = imp_median
data.info()

Age填入后：

3、Embarked填入众数

Embarked = data.loc[:,"Embarked"].values.reshape(-1,1)      # 将数据中的Embarked列变成二维
imp_mode = SimpleImputer(strategy="most_frequent")      # 用众数填
data.loc[:, "Embarked"] = imp_mode.fit_transform(Embarked)
data.info()

Embarked填入众数后：

4、补充（Numpy和Pandas也可以填充中位数）

data.loc[:,"Age"] = data.loc[:, "Age"].fillna(data.loc[:, "Age"].median())

5、附Narrativedata.csv数据
