Researchers have developed a new method for analyzing nonlinear dynamical systems that exhibit regime switching. This approach utilizes physics-informed neural networks to jointly estimate piecewise parameters and identify change-points, overcoming limitations of traditional separate detection and estimation methods. The technique involves analyzing local physical residuals and optimizing a unified physical loss function for simultaneous inference. Experiments on various benchmark systems show improved accuracy in both change-point localization and parameter estimation compared to existing decoupled approaches. AI
