所有已实现的接口:

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

public class VectorSlicer
extends Object
implements org.apache.flink.ml.api.Transformer<VectorSlicer>, VectorSlicerParams<VectorSlicer>

A Transformer that transforms a vector to a new feature, which is a sub-array of the original feature. It is useful for extracting features from a given vector.

Note that duplicate features are not allowed, so there can be no overlap between selected indices. If the max value of the indices is greater than the size of the input vector, it throws an IllegalArgumentException.
