Abstract:
The dependence structure of a categorical random vector is often studied by
means of a probabilistic graphical model. The most commonly used model is
the so-called Bayesian network which provides an intuitive and efficient
framework to assess (causal) dependencies. One of the major drawbacks of
these models is that they can only explicitly represent symmetric
dependencies, which, in practice, may not give a complete description of
the data dependence structure. Staged trees are a flexible class of
graphical models which can explicitly represent and model a wide array of
non-symmetric dependence. In this talk, I will provide an overview of this
model class and their application to a wide array of datasets. I will also
discuss a number of ongoing developments for staged trees, including
efficient structural learning, causal discovery, manipulations of the
graphs and the new stagedtrees R package. The talk is based on joint work
with Gherardo Varando (University of Valencia), Federico Carli and Eva
Riccomagno (University of Genova).

Cordiali saluti
