A database includes a list of members of a first group, a list of members of a second group, and ratings for at least some of the members of the second group. The database is accessed. The ratings are attributed to the members of the first group. A machine learning training set is built for a particular member of the first group. The training set includes class labels corresponding to the particular member's ratings for the members of the second group, and features that include supplied and predicted ratings from at least a subset of processed members of the first group. A predictor for the particular member of the first group is trained based on the machine learning training set. The predictor corresponding to the particular member is used to generate predicted ratings for one or more members of the second group the particular member has not rated. |
