Abstract: Physically informed neural networks (PINN) model are used to solve the one-and two-dimensional Sharam-Tasso-Olver equations.
The macroscopic equations and their initial margin conditions are used as physical information and transformed into the form of residuals,which are then used to construct a loss function to incorporate into the training process of the PINN model,and the Adam optimisation algorithm is used to achieve a high-precision solution.The numerical example results show that the loss function has high accuracy under a certain number of iterations,which verifies the reliability of the PINN model.

Key words: neural networks, physically informed neural network, Sharam-Tasso-Olver equation
