A Computational Framework for Infinite-Dimensional Bayesian Inverse Problems Part I: The Linearized Case, with Application to Global Seismic Inversion (2013, unknown): “We avoid storage of the time history of these wavefields by using a checkpointing method as employed in [17].”
A parametrization study for surface seismic full waveform inversion in an acoustic vertical transversely isotropic medium (2011, background): “D applications have also been reported (Epanomeritakis et al. 2008; Fichtner et al. 2009; Plessix 2009; Plessix & Perkins 2010; Sirgue et al. 2010; Vigh et al. 2010).”
Full-waveform inversion in three-dimensional PML-truncated elastic media (2015, methodology): “Biased search direction for λ Simultaneous inversion for both λ and μ is remarkably challenging [18].”
Mitigating local minima in full-waveform inversion by expanding the search space (2013, background): “Despite this clear advantage, the constrained formulation is unfortunately not widely adapted for FWI because it is unfeasible to store and update all 2M wavefields as part of an iterative procedure (Epanomeritakis et al. 2008).”
Hessian kernels of seismic data functionals based upon adjoint techniques (2011, methodology): “…by pre-conditioned conjugate-gradient algorithms (e.g. Mora 1987, 1988; Tape et al. 2007; Fichtner et al. 2009) and Newton-like methods (including Gauss–Newton and Levenberg–Marquardt) that use the approximate Hessian (e.g. Pratt et al. 1998; Epanomeritakis et al. 2008; Brossier et al. 2009).”
Implementing bound constraints and total-variation regularization in extended full waveform inversion with the alternating direction method of multiplier: application to large contrast media (2019, background): “…space that encompasses the unknown wavefield and the subsurface parameters is first projected onto the parameter space by computing exactly the incident wavefields in the current subsurface model before updating this later (Haber et al., 2000; Askan et al., 2007; Epanomeritakis et al., 2008).”
Seismic imaging: From classical to adjoint tomography (2012, background): “…problem, the optimization/inverse problem is usually solved based solely on local gradients, i.e., Fréchet derivatives of the misfit function (e.g., Epanomeritakis et al., 2008; Fichtner et al., 2009b; Tape et al., 2010), without forming and accessing the Hessian matrix (i.e., the second-order…”
