Web2 days ago · Learned multiphysics inversion with differentiable programming and machine learning. We present the Seismic Laboratory for Imaging and Modeling/Monitoring (SLIM) open-source software framework for computational geophysics and, more generally, inverse problems involving the wave-equation (e.g., seismic and medical ultrasound), … WebSeismic inversion is generally carried out by iterative data fitting in which the model updates are evaluated by solving the corresponding physics-based forward modeling. Local optimization methods are commonly used for finding an optimal model. Care must be taken to account for the ill posedness of the problem by imposing proper constraints. WebTo mitigate the cycle-skipping problem, Bunks et al. (1995) propose a multiscale inversion approach that initially inverts low-pass-filtered seismic data and then gradually admits higher frequencies as the iterations proceed. AlTheyab and Schuster (2015) remove the mid- and far-offset cycle-skipped seismic traces before inversion and gradually incorporate … should you wash your car everyday
