Neyman-Scott processes (NSPs) have been applied across a range of fields to model points or temporal events with a hierarchy of clusters. Markov chain Monte Carlo (MCMC) is typically used for posterior sampling in the model. However, MCMC’s mixing time can cause the resulting inference to be slow, a…
A Neyman-Scott process is a special case of a Cox process. The latent and observable stochastic processes are both Poisson processes. We consider a deep Neyman-Scott process in this paper, for which the building components of a network are all Poisson processes. We develop an efficient posterior sam…
The cover tree data structure speeds up exact nearest neighbor queries over arbitrary metric spaces. This paper makes cover trees even faster. In particular, we provide (1) a simpler definition of the cover tree that reduces the number of nodes from O(n) to exactly n, (2) an additional invariant tha…
