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

P Contucci, J Kertész, G Osabutey - PloS one, 2022 - journals.plos.org
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 …

Limit theorems for the cubic mean-field Ising model

P Contucci, E Mingione, G Osabutey - Annales Henri Poincaré, 2024 - Springer
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 …

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

P Contucci, G Osabutey, C Vernia - Physical Review E, 2023 - APS
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 relationship between anaemia and the use of treated bed nets among pregnant and non-pregnant women in Ghana

RK Ansah, S Tackie, RA Twum, K Tawiah, RK Boadi… - Plos one, 2024 - journals.plos.org
Studies have indicated that the risk of malaria, particularly its association with anaemia in
pregnant women, increases when treated bed nets are not used. This paper utilizes a …

Mathematical modelling of decision making: the case of motor insurance choices

RK Ansah, AA Opoku, K Tawiah, RK Boadi… - Journal of Mathematics …, 2024 - Springer
This paper employs a statistical mechanical model as a framework to investigate how
socioeconomic factors of individuals such as gender and place of residence influence their …

The Effect of Sociodemographic Factors on Female Educational Attainment: An Application of the Multipopulation Curie–Weiss Model

RK Ansah, K Tawiah, KA Asosega… - Journal of Applied …, 2024 - Wiley Online Library
In recent times, there have been a lot of advocacies to encourage females of all ages to
pursue education to the highest level. The Government of Ghana and its stakeholders have …

Influencing dynamics on social networks without knowledge of network microstructure

M Garrod, NS Jones - Journal of the Royal Society …, 2021 - royalsocietypublishing.org
Social network-based information campaigns can be used for promoting beneficial health
behaviours and mitigating polarization (eg regarding climate change or vaccines). Network …

Bayesian Inverse Ising Problem with Three-body Interactions

G Osabutey, R Richardson, GL Page - arXiv preprint arXiv:2404.05671, 2024 - arxiv.org
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 …

A statistical mechanics approach to the study of energy use behaviour

G Osabutey, AA Opoku, S Gyamfi - Journal of applied …, 2020 - Wiley Online Library
This paper proposes a statistical mechanical model for the energy conservation behaviour of
energy users. The model was inspired by the multipopulation Curie‐Weiss model and the …

Beyond pairwise interaction: the cubic mean-field Ising model

G Osabutey - 2024 - amsdottorato.unibo.it
The system under consideration comprises Ising spins, a homogeneous magnetic field, and
a constant two-spin interaction, augmented by a constant three-spin interaction term …
