Researchers have developed a new Bayesian inversion framework using Probabilistic Graphical Models (PGMs) to infer the health states of structural components. This approach addresses challenges in formulating likelihood functions and computing marginal likelihoods for high-dimensional discrete state parameters. The framework utilizes Graph Neural Networks (GNNs) for inference and incorporates a graph property-based training strategy to ensure accuracy across different graph scales and reduce computational costs.
