Instability of an inverse problem for the stationary radiative transport near the diffusion limit
Hongkai Zhao, Yimin Zhong
In this work, we study the instability of an inverse problem of radiative transport equation with angularly averaged measurement near the diffusion limit, i.e. the normalized mean…
Scalable Incremental Nonconvex Optimization Approach for Phase Retrieval
Ji Li, Jian-Feng Cai, Hongkai Zhao
We aim to find a solution to a system of quadratic equations of the form , , e.g., the well-known NP-har…
Intrinsic Complexity And Scaling Laws: From Random Fields to Random Vectors
Jennifer Bryson, Hongkai Zhao, Yimin Zhong
Random fields are commonly used for modeling of spatially (or timely) dependent stochastic processes. In this study, we provide a characterization of the intrinsic complexity of a…
A hybrid adaptive phase space method for reflection traveltime tomography
Hongkai Zhao, Yimin Zhong
We present a hybrid imaging method for a challenging travel time tomography problem which includes both unknown medium and unknown scatterers in a bounded domain. The goal is to re…
