For the venn code, I wrote up the approach here : http://www.benfrederickson.com/better-venn-diagrams/ Basically though, I'm using the non-linear CG method - so it doesn't require a positive definite matrix.

good point! I actually used this technique recently, to speed up a numerical optimization for laying out venn diagrams: http://www.benfrederickson.com/better-venn-diagrams/ I didn't think of it when I was writing

Once I figured out the solution, I was kicking myself for not figuring it our earlier =) I think I went wrong in 2 ways. My first attempt was to solve using calculus, and though I came up with a solution for the 2 circle case - I totally fa

Author here. I wrote this post a while back, but never submitted to HN. Its one of those posts that I wasn't sure if it would really resonate with anyone (like my most recent one on venn diagram layout algorithms). Anyways, If you have

Its amazing and insane =). I was trying to highlight the complexities behind something that many people people naively think is simple - I probably should have made the clearer based on the reaction elsewhere though

I like matrix factorization models too ! Most of the netflix prize style models will have problems with this sort of data though. The problem here is that you only have positive data, and no negative data: you can assume that artists the u

Thanks for the feedback! You're totally right that ratings datasets will skew positive. I was trying to get really get across that they aren't bimodal at all (unlike what some other people have claimed) and tend to look somewhat normal if
