1. A system for generating a set of coordinate vectors from a sparse graph of media object similarities, comprising using a computing device for: receiving a sparse graph of media object similarities; computing a set of coordinate vectors from the media object similarities of each media object comprising a subset of media objects represented by the sparse graph; updating the set of coordinate vectors by computing coordinate vectors for each remaining media object represented by the sparse graph which was not included in the subset of media objects; and storing the set of coordinate vectors to a computer readable storage media.
