Blind Modulo Analog-to-Digital Conversion of Vector Processes
Amir Weiss, Everest Huang, Or Ordentlich +1
In a growing number of applications, there is a need to digitize a (possibly high) number of correlated signals whose spectral characteristics are challenging for traditional analo…
Spiked Covariance Estimation from Modulo-Reduced Measurements
Elad Romanov, Or Ordentlich
Consider the rank-1 spiked model: , where is the spike intensity, is an unknown direction and $ξ\sim \mathcal{N}(0,1),…
Blind Modulo Analog-to-Digital Conversion
Amir Weiss, Everest Huang, Or Ordentlich +1
In a growing number of applications, there is a need to digitize signals whose spectral characteristics are challenging for traditional Analog-to-Digital Converters (ADCs). Example…
On Compressed Sensing of Binary Signals for the Unsourced Random Access Channel
Elad Romanov, Or Ordentlich
Motivated by applications in unsourced random access, this paper develops a novel scheme for the problem of compressed sensing of binary signals. In this problem, the goal is to de…
Critical Slowing Down Near Topological Transitions in Rate-Distortion Problems
Shlomi Agmon, Etam Benger, Or Ordentlich +1
In rate-distortion (RD) problems one seeks reduced representations of a source that meet a target distortion constraint. Such optimal representations undergo topological transition…
Constructing Multiclass Classifiers using Binary Classifiers Under Log-Loss
Assaf Ben-Yishai, Or Ordentlich
The construction of multiclass classifiers from binary elements is studied in this paper, and performance is quantified by the regret, defined with respect to the Bayes optimal log…
