A unifying tutorial on Approximate Message Passing
Oliver Y. Feng, Ramji Venkataramanan, Cynthia Rush +1
Over the last decade or so, Approximate Message Passing (AMP) algorithms have become extremely popular in various structured high-dimensional statistical problems. The fact that th…
Characterizing the SLOPE Trade-off: A Variational Perspective and the Donoho-Tanner Limit
Zhiqi Bu, Jason Klusowski, Cynthia Rush +1
Sorted l1 regularization has been incorporated into many methods for solving high-dimensional statistical estimation problems, including the SLOPE estimator in linear regression. I…
On the Robustness to Misspecification of -Posteriors and Their Variational Approximations
Marco Avella Medina, José Luis Montiel Olea, Cynthia Rush +1
-posteriors and their variational approximations distort standard posterior inference by downweighting the likelihood and introducing variational approximation errors. We show t…
Near-Optimal Coding for Many-user Multiple Access Channels
Kuan Hsieh, Cynthia Rush, Ramji Venkataramanan
This paper considers the Gaussian multiple-access channel (MAC) in the asymptotic regime where the number of users grows linearly with the code length. We propose efficient coding…
The Most Informative Order Statistic and its Application to Image Denoising
Alex Dytso, Martina Cardone, Cynthia Rush
We consider the problem of finding the subset of order statistics that contains the most information about a sample of random variables drawn independently from some known parametr…
