Researchers have developed a new method called Physics-Constrained Gaussian Process Regression (CONS-SOGP) to improve the reconstruction of structural mode shapes from limited sensor data. This approach integrates physical constraints, specifically a mass-orthogonality penalty, into the Gaussian Process Regression framework. Numerical tests on a multi-degree-of-freedom structure showed that CONS-SOGP provides more accurate and reliable expanded mode shapes compared to existing methods. AI
