Complexity bounds for Dirichlet process slice samplers
Beatrice Franzolini, Francesco Gaffi
Slice sampling is a standard Monte Carlo technique for Dirichlet process (DP)-based models, widely used in posterior simulation. However, formal assessments of the scalability of p…

Exchangeable random permutations with an application to Bayesian graph matching
Francesco Gaffi, Nathaniel Josephs, Lizhen Lin
We introduce a general Bayesian framework for graph matching grounded in a new theory of exchangeable random permutations. Leveraging the cycle representation of permutations and t…

Partially exchangeable stochastic block models for (node-colored) multilayer networks
Daniele Durante, Francesco Gaffi, Antonio Lijoi +1
Multilayer networks generalize single-layered connectivity data in several directions. These generalizations include, among others, settings where multiple types of edges are obser…
