This paper introduces a novel two-layer random hypergraph model to study opinion spread, incorporating higher-order interactions and adaptive behavior (changing opinions and workplaces). It investigates the impact of model parameters on polarization and homophily, analyzes the model as a Markov chain, and compares the performance of different statistical and machine learning methods for estimating key probabilities. The research is significant because it provides a framework for understanding opinion dynamics in complex social structures and explores the applicability of various machine learning techniques for parameter estimation in such models.
