Recovery of piecewise smooth density and Lamé parameters from high-frequency exterior Cauchy data
Sombuddha Bhattacharyya, Maarten V. de Hoop, Vitaly Katsnelson +1
We consider an isotropic elastic medium occupying a bounded domain D whose density and Lamé parameters are piecewise smooth. In the elastic wave initial value inverse problem, we a…
Trumpets: Injective Flows for Inference and Inverse Problems
Konik Kothari, AmirEhsan Khorashadizadeh, Maarten de Hoop +1
We propose injective generative models called Trumpets that generalize invertible normalizing flows. The proposed generators progressively increase dimension from a low-dimensional…
Unique recovery of electrical conductivity and magnetic permeability from Magneto-Telluric data
Yernat M. Assylbekov, Maarten V. de Hoop
We present a comprehensive mathematical study of the Magneto-Telluric (MT) method, on bounded domain in . We show that electrical conductivity and magnetic permeabili…
Learning the geometry of wave-based imaging
Konik Kothari, Maarten de Hoop, Ivan Dokmanić
We propose a general physics-based deep learning architecture for wave-based imaging problems. A key difficulty in imaging problems with a varying background wave speed is that the…
Reciprocity-gap misfit functional for Distributed Acoustic Sensing, combining data from passive and active sources
Florian Faucher, Maarten V. de Hoop, Otmar Scherzer
Quantitative imaging of sub-surface Earth's properties in elastic media is performed from Distributed Acoustic Sensing data. A new misfit functional based upon the reciprocity-gap…
Attention network forecasts time-to-failure in laboratory shear experiments
Hope Jasperson, David C. Bolton, Paul Johnson +3
Rocks under stress deform by creep mechanisms that include formation and slip on small-scale internal cracks. Intragranular cracks and slip along grain contacts release energy as e…
