ROMNet: a hybrid reduced order modeling and machine learning approach to waveform inversion
Liliana Borcea, Alexander Mamonov, Kui Ren +2
Waveform inversion seeks to estimate the wave speed of a heterogeneous, inaccessible medium, from time-resolved measurements of the waves at user controlled sensors. We consider th…

Data-driven reduced-order models for the radiative transfer equation
Yinxi Pan, Kui Ren, Shanyin Tong
We present a data-driven reduced-order modeling (ROM) framework for the zeroth angular moment of the solution to the radiative transfer equation (RTE) rather than the full phase-sp…

Chosen-Plaintext Attacks of Double Random Phase Encryption with Nonlinear Optical Media
Yan Cheng, Yiwei Chen, Kui Ren +1
This paper studies an inverse problem in nonlinear optical encryption. We examine chosen-plaintext attacks (CPA) on a nonlinear optical encryption strategy that integrates double r…
