Claim 4:
5. The method of claim 3, wherein training of the function for the affinity score comprises:
(a) fixing the correction factor to 1 to find a first best weight for each feature vector for a user-type pair, of a plurality of feature vectors for a plurality of user-type pairs;
(b) fixing a weight to the first best weight to re-estimate the correction factor;
(c) fixing the correction factor to the re-estimated correction factor to find a best weight for each feature vector for a user-type pair, of a plurality of feature vectors for a plurality of user-type pairs;
(d) fixing the weight to the best weight to re-estimate the correction factor; and
(e) reiterating steps (c) and (d) until a predetermined number of reiterations is reached or converged.
