Among the many families of nonperiodic tilings known so far, SCD tilings are still a bit mysterious. Here, we determine the diffraction spectra of point sets derived from SCD tilings and show that they have no absolutely continuous part, that they have a uniformly discrete pure point part on the axis Re3, and that they are otherwise supported on a set of concentric cylinder surfaces around this...

In many larger organizations like internationally operating companies, owners of analytical information systems must frequently cope with change. An important part of this problem is the restructuring of attributes serving as classification categories, so-called dimensions. This pattern language concerns itself with different ways of preparing for and dealing with changes in the real world and ...

Large-scale `1-regularized loss minimization problems arise in high-dimensional applications such as compressed sensing and high-dimensional supervised learning, including classification and regression problems. High-performance algorithms and implementations are critical to efficiently solving these problems. Building upon previous work on coordinate descent algorithms for `1-regularized probl...
