@chiwanpark thanks! Putting the finishing touches on
[approximate](https://github.com/danielblazevski/flink/blob/FLINK-1934/flink-staging/flink-ml/src/main/scala/org/apache/flink/ml/nn/zknn.scala)
z-knn -- but also need to do a LSH version of approximate knn since z-knn only
applies for dim < 30 (and z-value method is much quicker than LSH method for
dim < 30, but at least LSH makes since for dim > 30). Pretty excited about the
performance gain compared to exact knn.
I'll be presenting on knn for Flink at a Scala meetup in NY at Spotify on
May 24th and will definitely mention @chiwanpark and @tillrohrmann for all
their help!
