Hierarchical normalized finite point process: predictive structure and clustering
Abstract
Almost surely discrete random probability measures have received close attention in the Bayesian nonparametric community.
They have been used to model populations of individuals or latent parameters (in the mixture model setting) composed
of unfixed species with unknown proportions. In this framework, data are usually assumed to be exchangeable. However, the latter assumption is not appropriate when data are divided in multiple groups which may share the same species. If so, partially exchangeability accommodates the dependence across populations.
Best regards,
Monia Lupparelli
