> Hi Guys,
> I would like to clean up the Machine Learning library. A lot of the code in the ML Library does not conform to the original contribution guide. For example:
> Duplicate tests, different names, but exactly the same testcase:
> https://github.com/apache/flink/blob/master/flink-libraries/flink-ml/src/test/scala/org/apache/flink/ml/math/DenseVectorSuite.scala#L148
> https://github.com/apache/flink/blob/master/flink-libraries/flink-ml/src/test/scala/org/apache/flink/ml/math/DenseVectorSuite.scala#L164
> Lot of multi-line tests-cases:
> https://github.com/Fokko/flink/blob/master/flink-libraries/flink-ml/src/test/scala/org/apache/flink/ml/math/DenseVectorSuite.scala
> Mis-use of constants:
> https://github.com/apache/flink/blob/master/flink-libraries/flink-ml/src/main/scala/org/apache/flink/ml/math/DenseMatrix.scala#L58
> Please allow me to clean this up, and I'm looking forward to contribute more code, especially to the ML part. I've have been a contributor to Apache Spark and am happy to extend the codebase with new distributed algorithms and make the codebase more mature.
> Cheers, Fokko
