Researchers have developed a novel framework called Gabor-Enhanced Physics-Informed Neural Networks (Gabor-PINN) to improve the simulation of acoustic wavefields. This new method addresses the limitations of traditional PINNs, such as low-frequency bias and slow convergence, by incorporating trainable Gabor basis functions. The Gabor-PINN framework simplifies complexity by learning a coordinate transformation that captures the wavefield's oscillatory nature, leading to faster convergence, higher accuracy, and greater robustness compared to existing methods. The implementation is publicly available to encourage reproducibility and further research. AI
