Abstract: It is widely known that the full-waveform inversion (FWI) gradient contains both tomography and migration components. One of the key points for the successful implementation of FWI is to ...
Most existing point cloud upsampling methods have roughly three steps: feature extraction, feature expansion and 3D coordinate prediction. However, they usually suffer from two critical issues: (1) ...
Abstract: In this paper, we study the convergence properties of the natural gradient methods. By reviewing the mathematical condition for the equivalence between the Fisher information matrix and the ...
