Bayesian Inverse Ising Problem with Three-body Interactions

Autor: Osabutey, Godwin, Richardson, Robert, Page, Garritt L.

In this paper, we solve the inverse Ising problem with three-body interaction. Using the mean-field approximation, we find a tractable expansion of the normalizing constant. This facilitates estimation, which is known to be quite challenging for the

Limit theorems for the cubic mean-field Ising model

Autor: Contucci, Pierluigi, Mingione, Emanuele, Osabutey, Godwin

Publikováno v: Ann. Henri Poincar\'e (2024)

We study a mean-field spin model with three- and two-body interactions. The equilibrium measure for large volumes is shown to have three pure states, the phases of the model. They include the two with opposite magnetization and an unpolarized one wit

The inverse problem beyond two-body interaction: the cubic mean-field Ising model

Autor: Contucci, Pierluigi, Osabutey, Godwin, Vernia, Cecilia

In this paper we solve the inverse problem for the cubic mean-field Ising model. Starting from configuration data generated according to the distribution of the model we reconstruct the free parameters of the system. We test the robustness of this in

Human-AI ecosystem with abrupt changes as a function of the composition

Autor: Contucci, Pierluigi, Kertész, János, Osabutey, Godwin

Publikováno v: PLoS ONE 17(5): e0267310 (2022)

The progressive advent of artificial intelligence machines may represent both an opportunity or a threat. In order to have an idea of what is coming we propose a model that simulate a Human-AI ecosystem. In particular we consider systems where agents
