Recommender system on orange

Postby Sharapolas » Mon Jul 22, 2013 15:55

Dear all,

I would like to ask whether a more extensive documentation of NMF-addon is available?

If not then it would be nice if someone could guide me how to perform matrix factorization in Orange.

The setting:
From SQL I have data with three columns (user, item, rating). The first two are strings and the last one is float. My question would be how should I transform the data so that I could apply NMF and get back the factorization matrices?
