Curvature Recycling Douglas-Rachford Splitting: Transported Quasi-Newton Models for Expensive Smooth Proximal Subproblems
Musa Maharramov
We consider \[ \min_x f(x)+g(x), \] where is smooth but its value and gradient are expensive, while is nonsmooth and has a cheap proximal map. Douglas--Rachford splitting (…
Compressive Conjugate Directions: Linear Theory
Musa Maharramov, Stewart A. Levin
We present a powerful and easy-to-implement iterative algorithm for solving large-scale optimization problems that involve /total-variation (TV) regularization. The method is…
Total-variation minimization with bound constraints
Musa Maharramov, Stewart A. Levin
We present a powerful and easy-to-implement algorithm for solving constrained optimization problems that involve /total-variation regularization terms, and both equality and i…
Multi-model full-waveform inversion
Musa Maharramov, Biondo Biondi
We propose a multi-model formulation of full-waveform inversion that is similar to image decomposition into a "cartoon" and "texture" used in image processing. Inversion problem is…
Improved depth imaging by constrained full-waveform inversion
Musa Maharramov, Biondo Biondi
We propose a formulation of full-wavefield inversion (FWI) as a constrained optimization problem, and describe a computationally efficient technique for solving constrained full-wa…
Robust joint full-waveform inversion of time-lapse seismic data sets with total-variation regularization
Musa Maharramov, Biondo Biondi
We present a technique for reconstructing subsurface velocity model changes from time-lapse seismic survey data using full-waveform inversion (FWI). The technique is based on simul…
Sensitivity of the Static Earthquake Triggering Mechanism to Elastic Heterogeneity and Main Event Slip
Musa Maharramov
This paper has evolved out of our previous work on static stress transfer, where we used the full-space elastostatic Green's tensor to compute the Coulomb stress transfer impact of…
Towards Efficient Computation of Functional Determinants in QM and QFT
Musa Maharramov
We present an overview of the existing methods for computing functional determinants, and outline a possible way forward for Hamiltonians of higher dimensions without radial symmet…
Efficient depth extrapolation of waves in elastic isotropic media
Musa Maharramov
We propose a computationally efficient technique for extrapolating seismic waves in an arbitrary isotropic elastic medium. The method is based on factorizing the full elastic wave…
