类 Bucketizer

java.lang.Object

org.apache.flink.ml.feature.bucketizer.Bucketizer

所有已实现的接口:

Serializable, org.apache.flink.ml.api.AlgoOperator<Bucketizer>, org.apache.flink.ml.api.Stage<Bucketizer>, org.apache.flink.ml.api.Transformer<Bucketizer>, org.apache.flink.ml.common.param.HasHandleInvalid<Bucketizer>, org.apache.flink.ml.common.param.HasInputCols<Bucketizer>, org.apache.flink.ml.common.param.HasOutputCols<Bucketizer>, BucketizerParams<Bucketizer>, org.apache.flink.ml.param.WithParams<Bucketizer>

public class Bucketizer
extends Object
implements org.apache.flink.ml.api.Transformer<Bucketizer>, BucketizerParams<Bucketizer>

A Transformer that maps multiple columns of continuous features to multiple columns of discrete features, i.e., buckets indices. The indices are in [0, numSplitsInThisColumn - 1].

The `keep` option of HasHandleInvalid means that we put the invalid data in the last bucket of the splits, whose index is the number of the buckets.
