Wavelet compression, data fitting and approximation based on adaptive composition of Lorentz-type thresholding and Besov-type non-threshold shrinkage

In this study we initiate the investigation of a new advanced technique, proposed in Section 6 of [3], for generating adaptive Besov-Lorentz composite wavelet shrinkage strategies. We discuss some advantages of the Besov-Lorentz approach compared to firm thresholding.Validerad; 2010; 20100129 (grip
