Subject Re: out for memory

I mean I used to run SVD with my implementation storing only three 
arrays (user, item, rating), that I was able to fit in 3GB memory. I 
guess GenericDataModel takes up quite a lot of memory, because the data 
is indexed by users and by items, which is not necessary for SVD
