Orbit recovery under the rigid motions group
Amnon Balanov, Tamir Bendory, Dan Edidin
We study the orbit recovery problem under the rigid-motion group SE(n), where the objective is to reconstruct an unknown signal from multiple noisy observations subjected to unknow…

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)…
