Recovery Guarantees for Distributed-OMP
Chen Amiraz, Robert Krauthgamer, Boaz Nadler
We study distributed schemes for high-dimensional sparse linear regression, based on orthogonal matching pursuit (OMP). Such schemes are particularly suited for settings where a ce…

Distributed Sparse Normal Means Estimation with Sublinear Communication
Chen Amiraz, Robert Krauthgamer, Boaz Nadler
We consider the problem of sparse normal means estimation in a distributed setting with communication constraints. We assume there are machines, each holding -dimensional ob…
