On the value of the max-norm of the orthogonal projector onto splines with multiple knots
The supremum over all knot sequences of the max-norm of the orthogonal spline projector is studied with respect to the order k of the splines and their smoothness. It is first bou...

Improved Algorithms for Polynomial-Time Decay and Time-Decay with Additive Error
Abstract. We consider the problem of maintaining polynomial and exponential decay aggregates of a data stream, where the weight of values seen from the stream diminishes as time el...

Exploring Large Feature Spaces with Hierarchical Multiple Kernel Learning
For supervised and unsupervised learning, positive definite kernels allow to use large and potentially infinite dimensional feature spaces with a computational cost that only depe...

Performance of Space-Code-Division Multiple-Access Systems Using Reduced-Rank Detection
Abstract—In this contribution the performance of multipleinput multiple-output space-division, code-division multipleaccess (MIMO SCDMA) is investigated, when the low-complexity ...

Steering in Scale Space to Optimally Detect Image Structures
Detecting low-level image features such as edges and ridges with spatial filters is improved if the scale of the features are known a priori. Scale-space representations and wavele...
