Non-asymptotic goodness-of-fit tests and model selection in valued stochastic blockmodels
Félix Almendra-Hernández, Miles Bakenhus, Vishesh Karwa +2
A valued stochastic blockmodel (SBM) is a general way to view networked data in which nodes are grouped into blocks and links between them are measured by counts or labels. This fa…
Augmentation Algorithms for Integer Programs with Total Variation-like Regularization
Dominic Yang, Sven Leyffer, Miles Bakenhus
We address a class of integer optimization programs with a total variation-like regularizer and convex, separable constraints on a graph. Our approach makes use of the Graver basis…
New directions in algebraic statistics: Three challenges from 2023
Yulia Alexandr, Miles Bakenhus, Mark Curiel +11
In the last quarter of a century, algebraic statistics has established itself as an expanding field which uses multilinear algebra, commutative algebra, computational algebra, geom…
Sampling lattice points in a polytope: a Bayesian biased algorithm with random updates
Miles Bakenhus, Sonja Petrović
The set of nonnegative integer lattice points in a polytope, also known as the fiber of a linear map, makes an appearance in several applications including optimization and statist…
