Researchers have developed new analytical tools to explain the training performance of machine learning surrogate models used in power system dynamics. By adapting small-signal eigenvalue analysis from power systems, the Neural Tangent Kernel (NTK) method provides a modal interpretation of learning performance. This approach connects physical stiffness in power system models to optimization stiffness during Neural Network training, enabling the development of adaptive loss-weighting strategies and explaining why certain neural architectures like ActNet outperform standard NNs. These tools aim to move beyond trial-and-error design, offering physics-aware insights for creating more reliable machine learning surrogates in engineering applications. AI
