Collaborative ranking based on relative preference

Abstract (in Japanese) (See Japanese page) 
(in English) We consider a collaborative filtering problem with pairwise preference information. In this setting, the algorithm receives users' relative preferences over pairs of items and then the algorithm returns rankings over all item to users. Under this scheme, we prove generalization error bounds w.r.t. natural classes of hypotheses. In particular, our generalization bounds of rankings are built not only on the standard matrix completion techniques, but also on the algorithm LPKWIKSORT of Ailon for the rank aggregation problem.
