Efficient reductions from a Gaussian source with applications to statistical-computational tradeoffs

Mengqi Lou, Guy Bresler, Ashwin Pananjady

Given a single observation from a Gaussian distribution with unknown mean , we design computationally efficient procedures that can approximately generate an observation from a…

Accurate, provable and fast polychromatic tomographic reconstruction: A variational inequality approach

Mengqi Lou, Kabir Aladin Verchand, Sara Fridovich-Keil +1

We consider the problem of signal reconstruction for computed tomography (CT) under a nonlinear forward model that accounts for exponential signal attenuation, a polychromatic X-ra…
