[jira] [Updated] (SPARK-18408) API Improvements for LSH
[ https://issues.apache.org/jira/browse/SPARK-18408?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Yun Ni updated SPARK-18408:
---------------------------
Description:
As the first improvements to current LSH Implementations, we are planning to do the followings:
- Change output schema to {{Array of Vector}} instead of {{Vectors}}
- Use `numHashTables` as the dimension of {{Array}} and {{numHashFunctions}} as the dimension of {{Vector}}
- Rename {{RandomProjection}} to {{BucketedRandomProjectionLSH}}, {{MinHash}} to {{MinHashLSH}}
- Make randUnitVectors/randCoefficients private
