Binary classification of spoken words with passive phononic metamaterials
Tena Dubček, Daniel Moreno-Garcia, Thomas Haag +11
Mitigating the energy requirements of artificial intelligence requires novel physical substrates for computation. Phononic metamaterials have a vanishingly low power dissipation an…
Removing numerical dispersion from linear evolution equations
Jens Wittsten, Erik F. M. Koene, Fredrik Andersson +1
We describe a method for removing the numerical errors in the modeling of linear evolution equations that are caused by approximating the time derivative by a finite difference ope…
Four-dimensional tomographic reconstruction by time domain decomposition
Viktor V. Nikitin, Marcus Carlsson, Fredrik Andersson +1
Since the beginnings of tomography, the requirement that the sample does not change during the acquisition of one tomographic rotation is unchanged. We derived and successfully imp…
Perfect partial reconstructions for multiple simultaneous sources
Jens Wittsten, Fredrik Andersson, Johan Robertsson +1
A major focus of research in the seismic industry of the past two decades has been the acquisition and subsequent separation of seismic data using multiple sources fired simultaneo…
ESPRIT for multidimensional general grids
Fredrik Andersson, Marcus Carlsson
We present a new method for complex frequency estimation in several variables, extending the classical (1d) ESPRIT-algorithm. We also consider how to work with data sampled on non-…
Non-Convex Rank/Sparsity Regularization and Local Minima
Carl Olsson, Marcus Carlsson, Fredrik Andersson +1
This paper considers the problem of recovering either a low rank matrix or a sparse vector from observations of linear combinations of the vector or matrix elements. Recent methods…
