Researchers have developed PiGGO, a novel framework that combines physics-informed graph neural networks with Kalman filters for enhanced state estimation in complex nonlinear systems. This approach addresses challenges in digital twin deployment, such as model uncertainty and sparse sensing, by integrating learned dynamics with recursive Bayesian filtering. PiGGO enables more robust online virtual sensing and uncertainty-aware state estimation, outperforming traditional methods in numerical case studies. AI
