Recommendation Through Mixtures of Heterogeneous Item Relationships [article]

Wang-Cheng Kang, Mengting Wan, Julian McAuley
2018 arXiv   pre-print
Here we seek to develop a framework that is capable of combining such heterogeneous item relationships by simultaneously modeling (a) what modality of recommendation is a user likely to be susceptible  ...  Specific instances make use of signals ranging from user feedback, item relationships, geographic locality, social influence (etc.).  ...  We capture this intuition with a new model-Mixtures of Heterogeneous Recommenders (MoHR).  ...

Learning personal + social latent factor model for social recommendation

Yelong Shen, Ruoming Jin
2012 Proceedings of the 18th ACM SIGKDD international conference on Knowledge discovery and data mining - KDD '12  
There have been a few studies on social recommendations; however, they almost completely ignored the heterogeneity and diversity of the social relationship.  ...  Especially, the PSLF extracts the social factor vectors for each user based on the state-of-the-art mixture membership stochastic blockmodel, which can explicitly express the varieties of the social relationship  ...  Clearly, the existing approaches have largely ignored the heterogeneity and diversity of the social relationship.  ...
