Feynman Liang created SPARK-10230:
-------------------------------------
Summary: LDA public API should use docConcentration
Key: SPARK-10230
URL: https://issues.apache.org/jira/browse/SPARK-10230
Project: Spark
Issue Type: Improvement
Components: MLlib
Reporter: Feynman Liang
Priority: Minor
{{alpha}} is provided as an alias to {{docConcentration}} because it is
commonly used in literature. However, we should prefer {{docConcentration}}
since it is unambiguous what we mean.
The public API currently uses {{ {get,set}OptimizeAlpha}} but should instead
use {{ {get,set}OptimizeDocConcentration}}. We should also probably deprecate
any public API's using {{alpha}} directly and refer users to the corresponding
{{docConcentration}} methods.
