Serrin's overdetermined theorem and weak Bernoulli laws without Alt--Caffarelli regularity
Yi Ru-Ya Zhang
We study distributional Bernoulli-type conditions in geometrically irregular domains . Here the zero extension of to satisfies $$ Îu \;=\; c\,\mathcal{H}^{n…
Bayesian Signal Component Decomposition via Diffusion-within-Gibbs Sampling
Yi Zhang, Rui Guo, Yonina C. Eldar
In signal processing, the data collected from sensing devices is often a noisy linear superposition of multiple components, and the estimation of components of interest constitutes…
Bayesian Signal Separation via Plug-and-Play Diffusion-Within-Gibbs Sampling
Yi Zhang, Rui Guo, Yonina C. Eldar
We propose a posterior sampling algorithm for the problem of estimating multiple independent source signals from their noisy superposition. The proposed algorithm is a combination…
Plug-and-Play Latent Diffusion for Electromagnetic Inverse Scattering with Application to Brain Imaging
Rui Guo, Yi Zhang, Yhonatan Kvich +3
Electromagnetic (EM) imaging is an important tool for non-invasive sensing with low-cost and portable devices. One emerging application is EM stroke imaging, which enables early di…
