类 Imputer

java.lang.Object

org.apache.flink.ml.feature.imputer.Imputer

所有已实现的接口:

Serializable, org.apache.flink.ml.api.Estimator<Imputer,ImputerModel>, org.apache.flink.ml.api.Stage<Imputer>, org.apache.flink.ml.common.param.HasInputCols<Imputer>, org.apache.flink.ml.common.param.HasOutputCols<Imputer>, org.apache.flink.ml.common.param.HasRelativeError<Imputer>, ImputerModelParams<Imputer>, ImputerParams<Imputer>, org.apache.flink.ml.param.WithParams<Imputer>

public class Imputer
extends Object
implements org.apache.flink.ml.api.Estimator<Imputer,ImputerModel>, ImputerParams<Imputer>

The imputer for completing missing values of the input columns.

Missing values can be imputed using the statistics(mean, median or most frequent) of each column in which the missing values are located. The input columns should be of numeric type.

Note that the mean/median/most_frequent value is computed after filtering out missing values. All null values in the input columns are also treated as missing, and so are imputed.
