Modeling turbulent and self-gravitating fluids with Fourier neural operators
Keith Poletti, Stella S. R. Offner, Rachel A. Ward
Neural Operators (NOs) are a leading method for surrogate modeling of partial differential equations. Unlike traditional neural networks, which approximate individual functions, NO…
