Researchers have introduced a new neural network architecture called Non-Trainable Modification (NTM) designed for solving stochastic differential games (SDGs) on graphs. This architecture incorporates graph-guided sparsification, embedding fixed components that align with the graph's topology. This approach aims to improve interpretability and stability while reducing the number of trainable parameters, particularly in large-scale, sparse systems. The NTM architecture has been theoretically established for universal approximation in static games on graphs and has been integrated into existing game solvers, NTM-DP and NTM-DBSDE, demonstrating comparable performance and improved efficiency in numerical experiments.
