Researchers have developed a new framework to understand how individual training data points influence predictions in transportation networks. This physics-constrained approach accounts for physical laws, such as flow conservation, which traditional methods often overlook. The framework reveals that these physical constraints can alter the magnitude, direction, and spatial distribution of data influence compared to conventional methods. A case study on traffic prediction demonstrated that influential data points identified by this new method differ from those found using classical influence functions, offering a more physically consistent way to evaluate data influence in constrained learning problems.
