Sebastian,
Would it not be easier to just have SVDRecommender refresh the
DataModel first and then just make it recompute the factorization?
The problem is that when the DataModel is refreshed the userIDMapping
and itemIDMapping in the Factorizer also need to be refreshed and I
don't think th
Hi Chris,

There are two options I can see:
1) remember which Factorizer Cl
