WebbThe sklearn.preprocessing package provides several common utility functions and transformer classes to change raw feature vectors into a representation that is more suitable for the downstream estimators. In general, learning algorithms benefit from standardization of the data set. Webbclass sklearn.preprocessing.Imputer (*args, **kwargs) [source] Imputation transformer for completing missing values. Read more in the User Guide. Notes When axis=0, columns which only contained missing values at fit are discarded upon transform. Webbsklearn.preprocessing.Imputer的参数： sklearn.preprocessing.Imputer(missing_values=’NaN’, strategy=’mean’, axis=0, verbose=0, copy=True) 其中strategy代表对于空值的填充策略（默认为mean，即取所在列的平均数进行填充）： strategy='median'，代表取所在列的中位数进行填充 how to paint a painting on canvas
