1.one-hot编码

import numpy as np
from sklearn.preprocessing import OneHotEncoder

data = np.array([[1],[4]])
ohe = OneHotEncoder(sparse=False,handle_unknown='ignore') # 显示编码
onehot= ohe.fit_transform(data)
categories = ohe.n_values_[0]

print(onehot) # one-hot编码
print(categories) # 取值个数，从0开始计算的

结果：
