Online and Stable Learning of Analysis Operators
Michael Sandbichler, Karin Schnass
In this paper four iterative algorithms for learning analysis operators are presented. They are built upon the same optimisation principle underlying both Analysis K-SVD and Analys…

Convergence radius and sample complexity of ITKM algorithms for dictionary learning
Karin Schnass
In this work we show that iterative thresholding and K-means (ITKM) algorithms can recover a generating dictionary with K atoms from noisy sparse signals up to an error $\tilde…
