Feynman Liang be3e271641 [SPARK-9788] [MLLIB] Fix LDA Binary Compatibility ... 1. Add “asymmetricDocConcentration” and revert docConcentration changes. If the (internal) doc concentration vector is a single value, “getDocConcentration" returns it. If it is a constant vector, getDocConcentration returns the first item, and fails otherwise. 2. Give `LDAModel.gammaShape` a default value in `LDAModel` concrete class constructors. jkbradley Author: Feynman Liang <fliang@databricks.com> Closes #8077 from feynmanliang/SPARK-9788 and squashes the following commits: 6b07bc8 [Feynman Liang] Code review changes 9d6a71e [Feynman Liang] Add asymmetricAlpha alias bf4e685 [Feynman Liang] Asymmetric docConcentration 4cab972 [Feynman Liang] Default gammaShape		2015-08-11 14:21:53 -07:00
