Inverse Multislice Ptychography by Layer-wise Optimisation and Sparse Matrix Decomposition
Arya Bangun, Oleh Melnyk, Benjamin März +5
We propose algorithms based on an optimisation method for inverse multislice ptychography in, e.g. electron microscopy. The multislice method is widely used to model the interactio…
How many Fourier coefficients are needed?
Benedikt Diederichs, Mihail N. Kolountzakis, Effie Papageorgiou
We are looking at families of functions or measures on the torus which are specified by a finite number of parameters . The task, for a given family, is to look at a small numbe…
The spectral properties of Vandermonde matrices with clustered nodes
Dmitry Batenkov, Benedikt Diederichs, Gil Goldman +1
We study rectangular Vandermonde matrices with rows and irregularly spaced nodes on the unit circle, in cases where some of the nodes are "clustered" togethe…
Well-Posedness of Sparse Frequency Estimation
Benedikt Diederichs
The problem of estimating the frequencies of an exponential sum has been studied extensively over the last years. It can be understood as a sparse estimation problem, as it strives…
