Low-Rank Factorization of Determinantal Point Processes
Low-Rank Factorization of Determinantal Point Processes
Determinantal point processes (DPPs) have garnered attention as an elegant probabilistic model of set diversity. They are useful for a number of subset selection tasks, including product recommendation. DPPs are parametrized by a positive semi-definite kernel matrix. In this work we present a new method for learning the DPP kernel …
