Cross-modal Collaborative Manifold Propagation for Image Recommendation.

With the rapid evolution of social networks, the increasing user intention gap and visual semantic gap both bring great challenge for users to access satisfied contents. It becomes promising to investigate users' customized multimedia recommendation. In this paper, we propose cross-modal collaborative manifold propagation (CMP) for image recommendation. CMP leverages users' interest distribution to propagate images' user records, which lets users know the trend from others and produces interest-aware image candidates upon users' interests. Visual distribution is investigated simultaneously to propagate users' visual records along dense semantic visual manifold. Visual manifold propagation helps to estimate semantic accurate user-image correlations for the candidate images in recommendation ranking. Experimental performance demonstrate the collaborative user-image inferring ability of CMP with effective user interest manifold propagation and semantic visual manifold propagation in personalized image recommendation.
