Hello. I just started working on CF in MLlib. I am using trainImplicit because I only have implicit ratings like page views.
I am wondering which is a more appropriate form of ratings. Let's assume that view count is regarded as a rating and user 1 sees page 1 3 times and sees page 2 twice and so on. In this case, I think ratings can be formatted like the following 2 cases. (of course it is a RDD actually) A: user_id,page_id,rating(page view) 1,1,0.3 1,2,0.2 ... B: user_id,page_id,rating(page view) 1,1,0.1 1,1,0.1 1,1,0.1 1,2,0.1 1,2,0.1 ... It is allowed to have like B ? If it is, which is better ? ( is there any difference between them ?) Best, Hiro
