Optimization methods for frame conditioning and application to graph Laplacian scaling
Radu Balan, Mathew Begué, Chae Clark +1
A frame is scalable if each of its vectors can be rescaled in such a way that the resulting set becomes a Parseval frame. In this paper, we consider four different optimization pro…

Frames and Phaseless Reconstruction
Radu Balan
Frame design for phaseless reconstruction is now part of the broader problem of nonlinear reconstruction and is an emerging topic in harmonic analysis. The problem of phaseless rec…
