fPINNs: Fractional Physics-Informed Neural Networks [PDF]

open access: yesSIAM Journal on Scientific Computing, 2019
Physics-informed neural networks (PINNs) are effective in solving integer-order partial differential equations (PDEs) based on scattered and noisy data. PINNs employ standard feedforward neural networks (NNs) with the PDEs explicitly encoded into the NN using automatic differentiation, while the sum of the mean-squared PDE-residuals and the mean ...
