------------------------------
Summary: Support OR-AND amplification in Locality Sensitive
Hashing (LSH)
Key: SPARK-19771
URL: https://issues.apache.org/jira/browse/SPARK-19771
Project: Spark
Issue Type: Improvement
Components: ML
Affects Versions: 2.1.0
Reporter: Yun Ni
The current LSH implementation only supports AND-OR amplification. We need to
discuss the following questions before we goes to implementations:
(1) Whether we should support OR-AND amplification
(2) What API changes we need for OR-AND amplification
(3) How we fix the approxNearestNeighbor and approxSimilarityJoin internally.
