Velocity estimation via model order reduction
Alexander V. Mamonov, Liliana Borcea, Josselin Garnier +1
A novel approach to full waveform inversion (FWI), based on a data driven reduced order model (ROM) of the wave equation operator is introduced. The unknown medium is probed with p…
Waveform inversion with a data driven estimate of the internal wave
Liliana Borcea, Josselin Garnier, Alexander V. Mamonov +1
We study an inverse problem for the wave equation, concerned with estimating the wave speed, aka velocity, from data gathered by an array of sources and receivers that emit probing…
Waveform inversion via reduced order modeling
Liliana Borcea, Josselin Garnier, Alexander V. Mamonov +1
We introduce a novel approach to waveform inversion, based on a data driven reduced order model (ROM) of the wave operator. The presentation is for the acoustic wave equation, but…
