Mar 16, 2017 · Imputers from sklearn.preprocessing works well for numerical variables. But for categorical variables, mostly categories are strings, not numbers. To be able to use sklearn's imputers, you need to convert strings to numbers, then impute and finally convert back to strings. A better option is to use CategoricalImputer () from he sklearn_pandas ...
class sklearn.preprocessing. Imputer(missing_values='NaN', strategy='mean', axis=0, verbose=0, copy=True)[source]¶ Imputation transformer for completing missing values. Notes When axis=0, columns which only contained missing values at fitare discarded upon transform. When axis=1, an exception is raised if there are rows for which it is

26.09.2021 · Sklearn Simple Imputer Sklearn provides a module SimpleImputer that can be used to apply all the four imputing strategies for missing data that we discussed above. Sklearn Imputer vs SimpleImputer The old version of sklearn used to have a module Imputer for doing all the imputation transformation.
Sep 26, 2021 · Sklearn Imputer vs SimpleImputer. The old version of sklearn used to have a module Imputer for doing all the imputation transformation. However, the Imputer module is now deprecated and has been replaced by a new module SimpleImputer in the recent versions of Sklearn. So for all imputation purposes, you should now use SimpleImputer in Sklearn.
sklearn.impute .IterativeImputer ¶. Multivariate imputer that estimates each feature from all the others. A strategy for imputing missing values by modeling each feature with missing values as a function of other features in a round-robin fashion. Read more in the User Guide.
The KNNImputer class provides imputation for filling in missing values using the k-Nearest Neighbors approach. By default, a euclidean distance metric that supports missing values, nan_euclidean_distances , is used to find the nearest neighbors.
sklearn.impute .IterativeImputer ¶. Multivariate imputer that estimates each feature from all the others. A strategy for imputing missing values by modeling each feature with missing values as a function of other features in a round-robin fashion. Read more in the User Guide.
New in version 0.20: SimpleImputer replaces the previous sklearn.preprocessing.Imputer estimator which is now removed. Parameters missing_values int, float, str, np.nan or None, default=np.nan
