             Summary: Add standard scaler to ML library
                 Key: FLINK-1809
                 URL: https://issues.apache.org/jira/browse/FLINK-1809
             Project: Flink
          Issue Type: Improvement
          Components: Machine Learning Library
            Reporter: Till Rohrmann


Many ML algorithms require the input data to have mean 0 and a variance 1 for each individual feature [1]. Therefore, a {{Transformer}} which achieves exactly that would be a valuable addition to the machine learning library.
