Pedro Rodriguez commented on SPARK-5556:
----------------------------------------
Based on initial testing, I recall FastLDA in practice being O(1), should be
able to confirm that at a larger scale test soon. LightLDA definitely worth
looking into I think, at this point though my focus is on getting the FastLDA
Gibbs to a mergable state (tests pass, refactoring/api for LDA is good, and
performs at scale as good as or better than EM).
