Orlando Marigliano

Algebraic statistics, applied algebraic geometry at University of Genova


I am interested in the connections between algebraic geometry and the fields of statistics, data science, and the natural sciences. I am a postdoctoral researcher in the group "Mathematical Statistics", working with Eva Riccomagno. [er] My research project "Model Invariants in Algebraic Statistics" is funded by a MSCA Postdoctoral Fellowship. [link]

Main topics I'm working on: Algebraic statistical models, models for compositional data.

Other topics I'm interested in: the maximum likelihood degree, algebraic vision, algebraic sensitivity, random geometry and topology, singular learning theory, linear spaces of symmetric matrices, loss landscapes, staged trees, Bayesian networks, polynomial neural networks, the Wasserstein distance.
