hi,very informative talk; especially with those examples for handling cold start and seeding. any pointers on how the multiple entities are incorporated in the interaction matrix? I understand how user/item attributes may be incorporated in the interaction matrix but multiple entities is something that I am struggling to understand. Pointers to associated literature would help too.

This paper covers mixing different types: http://www.csie.ntu.edu.tw/~b97053/paper/Rendle2010FM.pdf (this paper covers a related but different technique). See figure 1 for an example of mixing ratings, indicator variables, and time into a single matrix.
