Abstract:
In this talk, I will discuss about parametric and nonparametric models for higher-order interactions with a focus on the statistical and computational aspects.
In fields like social, political and biological sciences, there is a clear need for analyzing higher-order interactions as opposed to pairwise interactions, which has been the main focus of statistical network analysis recently.
Generalized ?Block Models and ?Hypergraphons are powerful tools for modeling higher-order interactions.
The talk will introduce the models, ?present theoretical results ?highlight?ing? the challenges and differences that arise when analyzing higher-order interactions compared to pairwise interactions, and discuss applications and numerical results.
