Full Waveform Inversion and the Truncated Newton Method (2013, methodology): “The preconditioned steepest-descent uses a “direct” approximation of the inverse Hessian (for instance an approximation of its diagonal (Operto et al. 2006; Shin et al. 2001)).”
Robust elastic frequency‐domain full‐waveform inversion using the L1 norm (2009, methodology): “The diagonal of the pseudo-Hessian matrix [Shin et al., 2001] is used as an initial guess for the L-BFGS algorithm for both the L1 and the L2 criteria.”
