FileDataModel
I am using a FileDataModel and remove and insert preferences before estimating preferences. Do I need to rebuild the recommender after these methods are called for it to be reflected in the prediction?

That's true, it does now. Depending on the implementation, you may still
need to rebuild things to reflect the changes. Also note that this wouldn't
invalidate caches you put on top.

Thanks, Sean!
The remove/setPreference methods throw an UnsupportedOperationException. I read in an old thread that you had updated these methods to work. I'm not sure what I'm missing here. Can you point me in the right direction?

Yes to integrate any new data everything must be reloaded.
