Near-optimal bounds for signal recovery from blind phaseless periodic short-time Fourier transform
Tamir Bendory, Chi-yu Cheng, Dan Edidin
We study the problem of recovering a signal from samples of its phaseless periodic short-time Fourier transform (STFT): the magnitude of the Fourier transform of…
Sparse multi-reference alignment: sample complexity and computational hardness
Tamir Bendory, Oscar Mickelin, Amit Singer
Motivated by the problem of determining the atomic structure of macromolecules using single-particle cryo-electron microscopy (cryo-EM), we study the sample and computational compl…
Dihedral multi-reference alignment
Tamir Bendory, Dan Edidin, William Leeb +1
We study the dihedral multi-reference alignment problem of estimating the orbit of a signal from multiple noisy observations of the signal, acted on by random elements of the dihed…
Signal recovery from a few linear measurements of its high-order spectra
Tamir Bendory, Dan Edidin, Shay Kreymer
The -th order spectrum is a polynomial of degree in the entries of a signal , which is invariant under circular shifts of the signal. For , this p…
