The Regularized Functional Matching Pursuit
Volker Michel · Applied and numerical harmonic analysis · 2012
The choice of the centers of the “hat functions” is not flexible enough. In the case of the wavelet method, a quadrature grid is needed. In the case of splines, the grid of centers is immediately connected to the grid of data, and we cannot use a sparser grid of centers due to the algorithm. These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
