Orlando Marigliano

Algebraic statistics, applied algebraic geometry at KTH Stockholm


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 at Math Data Lab working with Kathlén Kohn. [mdl, kk]

Topics currently on my mind: linear Gaussian covariance models, linear spaces of symmetric matrices, multivariate boundary polynomial regression, Bayesian networks, staged trees, the maximum likelihood degree, models with ML degree one.

Other topics I'm interested in: random geometry and topology, singular learning theory, loss landscapes.

I am co-organizing a collaboration project on linear spaces of symmetric matrices. [link]
