A Polynomial Time MCMC Method for Sampling from Continuous Determinantal Point Processes

ICML 2019oral

We study the Gibbs sampling algorithm for discrete and continuous $k$-determinantal point processes. We show that in both cases, the spectral gap of the chain is bounded by a polynomial of $k$ and it is independent of the size of the domain. As an immediate corollary, we obtain sublinear time algori…

Composable Core-sets for Determinant Maximization: A Simple Near-Optimal Algorithm

ICML 2019oral

“Composable core-sets” are an efficient framework for solving optimization problems in massive data models. In this work, we consider efficient construction of composable core-sets for the determinant maximization problem. This can also be cast as the MAP inference task for “determinantal point proc…
