Preprint 'Tropical combinatorics of max-linear Bayesian networks' now with data

The fourth version to our paper about max-linear Bayesian networks and the combinatorics of their associated polytropes appeared on arXiv. This is joint work with Carlos Améndola.

Geometry and Combinatorics of max-linear Bayesian networks

These are slides for an expository talk given at the Institute for Theoretical Computer Science of the Universität zu Lübeck in June 2025. It serves as an overview for our paper on the tropical combinatorial classification of max-linear Bayesian networks, but also contains somewhat of an introduction to tropical polyhedra and different geometric constructions for them.

Directed separation in graphs

This is a simple graphical applet to calculate $d$- and $\star$-separation in directed acyclic graphs. Here, one can construct a directed graph by mouse, select some sets of vertices and see what is separated given the chosen semantics.
