Learning Attribute-to-Feature Mappings for Cold-Start Recommendations

Zeno Gantner, Lucas Drumond, Christoph Freudenthaler, Steffen Rendle, Lars Schmidt-Thieme
2010 2010 IEEE International Conference on Data Mining  
Cold-start scenarios in recommender systems are situations in which no prior events, like ratings or clicks, are known for certain users or items.  ...  We describe a method that maps such entity (e.g. user or item) attributes to the latent features of a matrix (or higherdimensional) factorization model.  ...  According to the authors, by assuming Bernoullidistributed observations, fLDA and RLFM would also be suitable for item recommendation with positive and negative feedback; nevertheless, the suitability  ...
