Serializable, org.apache.flink.ml.api.Estimator<StandardScaler,StandardScalerModel>, org.apache.flink.ml.api.Stage<StandardScaler>, org.apache.flink.ml.common.param.HasInputCol<StandardScaler>, org.apache.flink.ml.common.param.HasOutputCol<StandardScaler>, StandardScalerParams<StandardScaler>, org.apache.flink.ml.param.WithParams<StandardScaler>

public class StandardScaler
extends Object
implements org.apache.flink.ml.api.Estimator<StandardScaler,StandardScalerModel>, StandardScalerParams<StandardScaler>

An Estimator which implements the standard scaling algorithm.

Standardization is a common requirement for machine learning training because they may behave badly if the individual features of an input do not look like standard normally distributed data (e.g. Gaussian with 0 mean and unit variance).

This estimator standardizes the input features by removing the mean and scaling each dimension to unit variance.
