Primal dual pursuit: a homotopy based algorithm for the Dantzig selector
(Georgia Institute of Technology, 2008-07-10)
Consider the following system model y = Ax + e, where x is n-dimensional sparse signal, y is the measurement vector in a much lower dimension m, A is the measurement matrix and e is the error in our measurements. The ...
Dynamic compressive sensing: sparse recovery algorithms for streaming signals and video
(Georgia Institute of Technology, 2013-07-01)
This thesis presents compressive sensing algorithms that utilize system dynamics in the sparse signal recovery process. These dynamics may arise due to a time-varying signal, streaming measurements, or an adaptive signal ...
