Stochastic Gradient/Mirror Descent: Minimax Optimality and Implicit Regularization
Navid Azizan, Babak Hassibi
Stochastic descent methods (of the gradient and mirror varieties) have become increasingly popular in optimization. In fact, it is now widely recognized that the success of deep le…
Noncoherent Short-Packet Communication via Modulation on Conjugated Zeros
Philipp Walk, Peter Jung, Babak Hassibi
We introduce a novel blind (noncoherent) communication scheme, called modulation on conjugate-reciprocal zeros (MOCZ), to reliably transmit short binary packets over unknown finite…
Optimum Linear Codes with Support Constraints over Small Fields
Hikmet Yildiz, Babak Hassibi
We consider the problem of designing optimal linear codes (in terms of having the largest minimum distance) subject to a support constraint on the generator matrix. We show that th…
Manifold Optimization Over the Set of Doubly Stochastic Matrices: A Second-Order Geometry
Ahmed Douik, Babak Hassibi
Convex optimization is a well-established research area with applications in almost all fields. Over the decades, multiple approaches have been proposed to solve convex programs. T…
Further Progress on the GM-MDS Conjecture for Reed-Solomon Codes
Hikmet Yildiz, Babak Hassibi
Designing good error correcting codes whose generator matrix has a support constraint, i.e., one for which only certain entries of the generator matrix are allowed to be non-zero,…
A Precise Analysis of PhaseMax in Phase Retrieval
Fariborz Salehi, Ehsan Abbasi, Babak Hassibi
Recovering an unknown complex signal from the magnitude of linear combinations of the signal is referred to as phase retrieval. We present an exact performance analysis of a recent…
