contents A LightGBM-Incorporated absorbing boundary condition (ABC) computation approach for the wave-equation-based the radial point interpolation meshless (RPIM) method is proposed to simulate wave propagation in open space during the computation process. Different strageties are implemented for replacing the conventional perfectly matched layers (PMLs) in the computational domain. In this work, the model is used to predict the field components on the boundary at each time step to improve computational efficiency. The effectiveness and high efficiency of our method is verified by numerical experiments.
