Stable Blind Deconvolution over the Reals from Additional Autocorrelations
Philipp Walk, Babak Hassibi
Recently the one-dimensional time-discrete blind deconvolution problem was shown to be solvable uniquely, up to a global phase, by a semi-definite program for almost any signal, pr…
Improving Distributed Gradient Descent Using Reed-Solomon Codes
Wael Halbawi, Navid Azizan-Ruhi, Fariborz Salehi +1
Today's massively-sized datasets have made it necessary to often perform computations on them in a distributed manner. In principle, a computational task is divided into subtasks w…
Short-Message Communication and FIR System Identification using Huffman Sequences
Philipp Walk, Peter Jung, Babak Hassibi
Providing short-message communication and simultaneous channel estimation for sporadic and fast fading scenarios is a challenge for future wireless networks. In this work we propos…
Entropic Causality and Greedy Minimum Entropy Coupling
Murat Kocaoglu, Alexandros G. Dimakis, Sriram Vishwanath +1
We study the problem of identifying the causal relationship between two discrete random variables from observational data. We recently proposed a novel framework called entropic ca…
