abstract = {<p style="text-align: justify;">In this paper, we develop a cell-average based neural network (CANN)
method for solving the Hunter-Saxton equation with its zero-viscosity and zero-dispersion limits. Motivated from the finite volume schemes, the cell-average based
neural network method is constructed based on the finite volume integrals of the original PDEs. Supervised training is designed to learn the solution average difference
between two neighboring time steps. The training data set is generated by the cell average based on a single initial value of the given PDE. The training process employs
multiple time levels of cell averages to maintain stability and control temporal accumulation errors. After being well trained based on appropriate meshes, this method
can be utilized like a regular explicit finite volume method to evolve the solution under
large time steps. Furthermore, it can be applied to solve different type of initial value
problems without retraining the neural network. In order to validate the capability
and robustness of the CANN method, we also utilize it to deal with the corrupted
learning data which is generated from the Gaussian white noise. Several numerical
examples of different types of Hunter-Saxton equations are presented to demonstrate
the effectiveness, accuracy, capability, and robustness of the proposed method.</p>},
