Subject Fastest way to compute compute correlation between users and generate new recommendations
Date Tue, 19 Oct 2010 11:42:16 GMT

I am trying to use Mahout this day.
I wanted to ask about the fastest way to compute correlations between a
large number of users and recommend new recommendations?

It is better to use a FileDataModel ?

It is possible to precompute user correlation ? when I stock the result and
how i could use it?

Thank you for your help.
