Euclidean distance geometry and the orthogonal beltway problem
Dan Edidin, Arun Suresh
The orthogonal beltway problem is the problem of recovering the -orbit of a -function supported at a finite number of points in $\r^n$ from its auto-correlation…

A transversality theorem for semi-algebraic sets with application to signal recovery from the second moment and cryo-EM
Tamir Bendory, Nadav Dym, Dan Edidin +1
Semi-algebraic priors are ubiquitous in signal processing and machine learning. Prevalent examples include a) linear models where the signal lies in a low-dimensional subspace; b)…

Phase retrieval with semi-algebraic and ReLU neural network priors
Tamir Bendory, Nadav Dym, Dan Edidin +1
The key ingredient to retrieving a signal from its Fourier magnitudes, namely, to solve the phase retrieval problem, is an effective prior on the sought signal. In this paper, we s…
