-----------------------------------
Component/s: ML
> Changes to fix Nearest Neighbor Search for LSH
> ----------------------------------------------
>
> Key: SPARK-18454
> URL: https://issues.apache.org/jira/browse/SPARK-18454
> Project: Spark
> Issue Type: Improvement
> Components: ML
> Reporter: Yun Ni
>
> We all agree to do the following improvement to Multi-Probe NN Search:
> (1) Use approxQuantile to get the {{hashDistance}} threshold instead of doing
> full sort on the whole dataset
> Currently we are still discussing the following:
> (1) What {{hashDistance}} (or Probing Sequence) we should use for {{MinHash}}
> (2) What are the issues and how we should change the current Nearest Neighbor
> implementation
