Subject help for item based recommender
Date Mon, 26 May 2008 11:58:27 GMT

I am going over the documentation and meant to do a item based recomender.
I understand that the datamodel is fed with triplets in form of:

userid, itemid, likingscore

There is a part in the code which says:

// Construct the list of pre-compted correlations
Collection<GenericItemCorrelation.ItemItemCorrelation> correlations =
ItemCorrelation itemCorrelation = new GenericItemCorrelation(correlations);

and the explanation mentions we have to feed a list of pre-computed
corelations to the GenericItemCorelation.

How do we pre-compute corelations?
