所有已实现的接口:

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

public class DCT
extends Object
implements org.apache.flink.ml.api.Transformer<DCT>, DCTParams<DCT>

A Transformer that takes the 1D discrete cosine transform of a real vector. No zero padding is performed on the input vector. It returns a real vector of the same length representing the DCT. The return vector is scaled such that the transform matrix is unitary (aka scaled DCT-II).

See https://en.wikipedia.org/wiki/Discrete_cosine_transform#DCT-II(DCT-II in Discrete cosine transform).
