java.lang.Object

org.apache.flink.ml.feature.ngram.NGram

所有已实现的接口:

Serializable, org.apache.flink.ml.api.AlgoOperator<NGram>, org.apache.flink.ml.api.Stage<NGram>, org.apache.flink.ml.api.Transformer<NGram>, org.apache.flink.ml.common.param.HasInputCol<NGram>, org.apache.flink.ml.common.param.HasOutputCol<NGram>, NGramParams<NGram>, org.apache.flink.ml.param.WithParams<NGram>

public class NGram
extends Object
implements org.apache.flink.ml.api.Transformer<NGram>, NGramParams<NGram>

A Transformer that converts the input string array into an array of n-grams, where each n-gram is represented by a space-separated string of words. If the length of the input array is less than `n`, no n-grams are returned.

See https://en.wikipedia.org/wiki/N-gram.
