Neural-operator surrogates for outdoor acoustics using parameterized wind and terrain profilesa).

Outdoor sound propagation is strongly shaped by boundary layer meteorology and terrain, yet high-fidelity simulation remains too expensive for rapid scenario studies. This paper shows the development of neural-operator surrogates that map parameterized wind profiles and/or terrain profiles to acoustic fields over a reg...

Rational neural networks for tracking complex singularities of nonlinear PDEs

We present a neural network-based method for numerical analytic continuation of solutions of nonlinear partial differential equations (PDEs) and detection of their complex singularities. The proposed framework employs"unsafe"Pad\'e activation units (PAUs) as activation functions, together with a novel backpropagation-f...
