Pytorch seismic extrapolate low frequency
WebIn this project, a deep learning-based approach is proposed to extrapolate the low-frequency data. Specifically, we propose a robust progressive learning (RPL) algorithm that combines physics-guided FWI and data-driven deep learning technology. The proposed method is robust against the choice of the initial model. Webthe data inference is conducted with the same deep CNN to extrapolate lower frequency sampling points. THEORY For low-frequency extrapolation, any data inference technique …
