In this paper, we are concerned with regularized regression problems where the prior regularizer is a proper lower semicontinuous and convex function which is also partly smooth relative to a Riemannian submanifold. This encompasses as special cases several known penalties such as the Lasso (`-norm), the group Lasso (`−`-norm), the `∞-norm, and the nuclear norm. This also includes so-called ana...

In this work, we propose a novel approach for the semi-supervised node classification. Precisely, we propose a method which takes labels in the local neighborhood of different locality levels into consideration. Most previous approaches that tackle the problem of node classification consider nodes to be similar, if they have shared neighbors or are close to each other in the graph. Recent metho...

Semi-leptonic and radiative semi-inclusive decays of heavy mesons are currently under intense investigation. Non perturbative physics seems to be more manageable in such decays, and there is hope for a reduction of theoretical assumptions and a more stringent comparison with experimental data. Several effective approaches to such decays are available. Most commonly, in order to calculate the de...
