Item Co-occurrence

User 962 | 11/20/2014, 1:20:57 PM

Hello,

Are there plans to include co-occurence calculations in Graphlab?

Before completely implementing an algorithm like FPGrowth, it seems like finding pairwise co-occurences is already done within ItemSimilarityRecommender, and would only require some simple modification of the output as Danny Bickson notes <a href="https://groups.google.com/d/msg/graphlab-kdd/0eh2nEHitWk/w6FwwmP459AJ">here</a>.

Thanks, Myles

Hi Myles, A workaround would be to multiply the score you get from from the getsimilaritems function call by the sum of of users who rated either item.
