A couple things happen above: let us assume that we have n users and m items, so our ratings matrix is n×m.We introduce the symbol Y (with dimensioins m×k) to represent all item row vectors vertically stacked on each other.Also, the row vector r_u just represents users u’s row from the ratings matrix with all the ratings for all the items (so it has dimension 1×m). Traditionally, the dot product or higher order equivalents have been used to combine two or more embeddings, e.g., most notably in matrix factorization. IJCAI, 2017. code. 2015.
