类 PolynomialExpansion

java.lang.Object

org.apache.flink.ml.feature.polynomialexpansion.PolynomialExpansion

所有已实现的接口:

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

public class PolynomialExpansion
extends Object
implements org.apache.flink.ml.api.Transformer<PolynomialExpansion>, PolynomialExpansionParams<PolynomialExpansion>

A Transformer that expands the input vectors in polynomial space.

Take a 2-dimension vector as an example: `(x, y)`, if we want to expand it with degree 2, then we get `(x, x * x, y, x * y, y * y)`.

For more information about the polynomial expansion, see http://en.wikipedia.org/wiki/Polynomial_expansion.
