" Standardization " and " normalization " These two Chinese words refer to four Feature scaling( Feature scaling ) Method :
1. Zoom to mean 0, The variance of 1（Standardization——StandardScaler()）
2. Zoom to 0 and 1 Between （Standardization——MinMaxScaler()）
3. Zoom to -1 and 1 Between （Standardization——MaxAbsScaler()）
4. Zoom to 0 and 1 Between , Preserve the distribution of the original data （Normalization——Normalizer()）
Due to Chinese Translation , There are various definitions of normalization and regularization on the Internet ！
