Bayesian nonparametric temporal dynamic clustering via autoregressive Dirichlet priors
Maria De Iorio, Stefano Favaro, Alessandra Guglielmi +1
In this paper we consider the problem of dynamic clustering, where cluster memberships may change over time and clusters may split and merge over time, thus creating new clusters a…
Monte Carlo Co-Ordinate Ascent Variational Inference
Lifeng Ye, Alexandros Beskos, Maria De Iorio +1
In Variational Inference (VI), coordinate-ascent and gradient-based approaches are two major types of algorithms for approximating difficult-to-compute probability densities. In re…
Is infinity that far? A Bayesian nonparametric perspective of finite mixture models
Raffaele Argiento, Maria De Iorio
Mixture models are one of the most widely used statistical tools when dealing with data from heterogeneous populations. This paper considers the long-standing debate over finite mi…
