Mahout "Inverse" Recommender
With Mahout recommender (with Hadoop map reduce), the typical question is
"which movies this particular user may be interested in?". How do we
reverse that question and instead ask for "which users may be interested
in this particular movie"?
And eventually to take it one step further: "for this list of movies,
which users are the most suitable candidates?"
In reality this is not about movies, but to build a recommendation to pick
top candidates with resources/preferences that most suitably meet a
particular set of requirements.
Any thoughts how to solve this with Mahout, in particular using hadoop
map-reduce jobs?
