The method is based on the inspection of the behavior of discrepan-cies of a multi-penalty regularization with a component-wise penalization forsmall and large values of regularization parameters. We provide the justifica-tion of the proposed method under a certain condition on sampling operators.The effectiveness of the method is demonstrated in the example with syntheticdata and in the reconstruction of gene regulatory networks. In the latter ex-ample, the obtained results provide a clear evidence of the competitiveness ofthe proposed method.}, year = {2017}, journal = {Recent Applications of Harmonic Analysis to Function Spaces, Differential Equations, and Data Science}, volume = {2}, edition = {Novel Methods in Harmonic Analysis,}, pages = {889-916}, publisher = {Springer International Publishing}, url = {http://www.springer.com/de/book/9783319555553}, editor = {Isaac Pesenson}, }
