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…

When data driven reduced order modeling meets full waveform inversion
Liliana Borcea, Josselin Garnier, Alexander V. Mamonov +1
Waveform inversion is concerned with estimating a heterogeneous medium, modeled by variable coefficients of wave equations, using sources that emit probing signals and receivers th…
