Searching for gravitational waves from compact binary coalescence (CBC) is performed by matched filtering the observed strain data gravitational-wave observatories against a discrete set of waveform templates designed to accurately approximate expected signal, and are chosen efficiently cover target search region. The computational cost scales with both number required parameter space in-band d...

Abstract The main purpose of this work is to provide an efficient scheme for constructing kernel-based reduced interpolation models. In the existing literature such problems are mainly addressed via well-established knot insertion or removal schemes. Such iterative strategies usually quite demanding from a computational point view and our goal study implementation data approaches, namely basis ...

Abstract We propose and analyze new numerical methods to evaluate fractional norms apply powers of elliptic operators. By means a reduced basis method, we project small dimensional subspace where explicit diagonalization via the eigensystem is feasible. The method relies on several independent evaluations $$({{\,\mathrm{I}\,}}-t_i^2\Delta )^{-1}f$$ <mml:math xmlns:mml="http://www.w3.org/1998/Ma...
