归一化(Normalization)和标准化(Standardization)
2022-07-27 17:11:00 【遨游的菜鸡】
"标准化"和"归一化"这两个中文词要指代四种Feature scaling(特征缩放)方法:
1.缩放到均值为0,方差为1(Standardization——StandardScaler())
2.缩放到0和1之间(Standardization——MinMaxScaler())
3.缩放到-1和1之间(Standardization——MaxAbsScaler())
4.缩放到0和1之间,保留原始数据的分布(Normalization——Normalizer())
由于中文翻译,网上对于归一化和正则化的定义五花八门!
