java.lang.Object

org.apache.flink.ml.feature.interaction.Interaction

所有已实现的接口:

Serializable, org.apache.flink.ml.api.AlgoOperator<Interaction>, org.apache.flink.ml.api.Stage<Interaction>, org.apache.flink.ml.api.Transformer<Interaction>, org.apache.flink.ml.common.param.HasInputCols<Interaction>, org.apache.flink.ml.common.param.HasOutputCol<Interaction>, InteractionParams<Interaction>, org.apache.flink.ml.param.WithParams<Interaction>

public class Interaction
extends Object
implements org.apache.flink.ml.api.Transformer<Interaction>, InteractionParams<Interaction>

A Transformer that takes vector or numerical columns, and generates a single vector column that contains the product of all combinations of one value from each input column.

For example, when the input feature values are Double(2) and Vector(3, 4), the output would be Vector(6, 8). When the input feature values are Vector(1, 2) and Vector(3, 4), the output would be Vector(3, 4, 6, 8). If you change the position of these two input Vectors, the output would be Vector(3, 6, 4, 8).
