Beta diffusion trees and hierarchical feature allocations
Creighton Heaukulani, David A. Knowles, Zoubin Ghahramani
We define the beta diffusion tree, a random tree structure with a set of leaves that defines a collection of overlapping subsets of objects, known as a feature allocation. A genera…
A reversible infinite HMM using normalised random measures
Konstantina Palla, David A. Knowles, Zoubin Ghahramani
We present a nonparametric prior over reversible Markov chains. We use completely random measures, specifically gamma processes, to construct a countably infinite graph with weight…
An Infinite Latent Attribute Model for Network Data
Konstantina Palla, David Knowles, Zoubin Ghahramani
Latent variable models for network data extract a summary of the relational structure underlying an observed network. The simplest possible models subdivide nodes of the network in…
