类 OneHotEncoder

java.lang.Object

org.apache.flink.ml.feature.onehotencoder.OneHotEncoder

所有已实现的接口:

Serializable, org.apache.flink.ml.api.Estimator<OneHotEncoder,OneHotEncoderModel>, org.apache.flink.ml.api.Stage<OneHotEncoder>, HasHandleInvalid<OneHotEncoder>, HasInputCols<OneHotEncoder>, HasOutputCols<OneHotEncoder>, OneHotEncoderParams<OneHotEncoder>, org.apache.flink.ml.param.WithParams<OneHotEncoder>

public class OneHotEncoder
extends Object
implements org.apache.flink.ml.api.Estimator<OneHotEncoder,OneHotEncoderModel>, OneHotEncoderParams<OneHotEncoder>

An Estimator which implements the one-hot encoding algorithm.

Data of selected input columns should be indexed numbers in order for OneHotEncoder to function correctly.
