New Feature Interaction Models Enhance Physics-Informed Neural Networks

Researchers have developed new methods to enhance the expressiveness of physics-informed neural networks (PINNs) and neural operators. By incorporating feature interaction modules inspired by factorization machines, these models can better capture complex relationships between variables in parameterized partial differential equations (PDEs). The proposed FM-PINN and FM-Operator models show particular effectiveness in handling nonlinear conservation laws and problems with sharp gradients or discontinuities, leading to significant accuracy improvements on challenging equations.
