Pitman-Yor Diffusion Trees
David A. Knowles, Zoubin Ghahramani
We introduce the Pitman Yor Diffusion Tree (PYDT) for hierarchical clustering, a generalization of the Dirichlet Diffusion Tree (Neal, 2001) which removes the restriction to binary…
Generalised Wishart Processes
Andrew Gordon Wilson, Zoubin Ghahramani
We introduce a stochastic process with Wishart marginals: the generalised Wishart process (GWP). It is a collection of positive semi-definite random matrices indexed by any arbitra…
Nonparametric Bayesian sparse factor models with application to gene expression modeling
David Knowles, Zoubin Ghahramani
A nonparametric Bayesian extension of Factor Analysis (FA) is proposed where observed data is modeled as a linear superposition, , of a potentially infinit…
Bayesian two-sample tests
Karsten M. Borgwardt, Zoubin Ghahramani
In this paper, we present two classes of Bayesian approaches to the two-sample problem. Our first class of methods extends the Bayesian t-test to include all parametric models in t…
Kronecker Graphs: An Approach to Modeling Networks
Jure Leskovec, Deepayan Chakrabarti, Jon Kleinberg +2
How can we model networks with a mathematically tractable model that allows for rigorous analysis of network properties? Networks exhibit a long list of surprising properties: heav…
