Should questions about machine learning (ML) be asked here or at Data Science.SE? When Data Science was still a proposal, the discussion indicated these questions should be asked here. Later discussions indicated the two sites should be merged.
The tour page says "Cross Validated is a question and answer site for people interested in... machine learning." This is also a fully graduated (i.e. no longer in beta) site. However, the Data Science tour page says "Data Science Stack Exchange is a question and answer site for Data science professionals, Machine Learning specialists, and those interested in learning more about the field." A mod there claims that CV is the right site for statistics, not ML questions, but that DS is for ML questions.
As of this posting, the ML tag has 4,128 questions here and 498 there, which might suggest they fit better here.
However, the opposite conclusion might be reached by noting that under "all questions" the totals are 65,571 here and 1,505 there so ML questions are 6.3% of questions here and 33% of questions there.
Where do ML questions belong?
