What algorithm are you using to make recommendations? I've been looking around in the recommendable source but can't seem to find it.
That's under `lib/recommendable/acts_as_recommended_to.rb` towards the bottom. It's a combination of the `similarity_with(rater)` and `predict(object)` methods. Additionally, I detail the algorithm here: http://davidcelis.com/blog/2012/02/07/collaborative-filterin...

Recommendations start getting generated immediately after you rate a beer. The site is in its infancy, of course, so recommendations may start out rocky but they'll get better as more people (and you) rate more beers. The sad state of the cold start! How long it takes for the recommendations to refresh is tougher to say, but it shouldn't be more than a few minutes. I can see that the workers that process them are act…

I rated a few beers, but my recommendation screen is empty. I get that it's a new site, so I can accept that it might be tough to get recommendations right away, but it would be really helpful to explain why there aren't any results. Is it because I haven't rated enough beers? Is it because there aren't enough other users that have similar tastes? Is it because there's a delay before results show up? Also, I had to t…
EDIT: looks like the process had actually silently died at some point, but was still reporting as running. I think I've fixed the issue now.
