Seismic wavefield solutions via physics-guided generative neural operator
Shijun Cheng, Mohammad H. Taufik, Tariq Alkhalifah
Current neural operators often struggle to generalize to complex, out-of-distribution conditions, limiting their ability in seismic wavefield representation. To address this, we pr…
