Reservoir optimization in recurrent neural networks using properties of Kronecker product
Martin Hasler, Ali Ajdari Rad, Mahdi Jalili
Recurrent neural networks based on reservoir computing are increasingly being used in many applications. Optimization of the topological structure of the reservoir and the internal connection weights for a given task is one of the most important problems i ...
2010A new extended matrix logarithm formulation for the simulation of viscoelastic fluids by spectral elements
Michel Deville, Nicolas Fietier, Azadeh Jafari
This study presents a new algorithm developed in order to remove instabilities observed in the simulation of unsteady viscoelastic fluid flows in the framework of the spectral element method. In this study, we consider a particular model of the finite exte ...
2010Universal Bounds And Semiclassical Estimates For Eigenvalues Of Abstract Schrodinger Operators
We prove trace inequalities for a self-adjoint operator on an abstract Hilbert space, which extend those known previously for Laplacians and Schrodinger operators, freeing them from restrictive assumptions on the nature of the spectrum and allowing operato ...
2010On the influence of gravel bed dynamics on velocity power spectra
A series of flume experiments were conducted to study the effect of bed form dynamics on the flow over a gravel bed comprising a wide distribution of grain sizes. Instantaneous high-frequency streamwise flow velocities were sampled using an acoustic Dopple ...
2010A general framework for homotopic descent and codescent
In this paper we elaborate a general homotopy-theoretic framework in which to study problems of descent and completion and of their duals, codescent and cocompletion. Our approach to homotopic (co)descent and to derived (co)completion can be viewed as $\in ...
2010Spectral Methods
Spectral methods, particularly in their multidomain version, have become firmly established as a mainstream tool for scientific and engineering computation. While retaining the tight integration between the theoretical and practical aspects of spectral met ...
Springer2007Power Spectra of Multipath Faded Pulse Trains
We address the problem of modeling received pulse trains in a multipath fading channel and of computing their exact spectrum. We propose a model based on point processes. Such model is very general, simple and tractable and it allows to account for various ...
2005Generalized Biorthogonal Daubechies Wavelets
Michaël Unser, Thierry Blu, Cédric René Jean Vonesch
We propose a generalization of the Cohen-Daubechies-Feauveau (CDF) and 9⁄7 biorthogonal wavelet families. This is done within the framework of non-stationary multiresolution analysis, which involves a sequence of embedded approximation spaces generated by ...
SPIE2005Linear stability analysis of time-dependent algorithms with spectral element methods for the simulation of viscoelastic flows
Michel Deville, Nicolas Fietier
In order to better understand the sources of numerical instabilities occurring in the simulation of time-dependent flows of viscoelastic fluids at high Weissenberg numbers, we have used various types of linear stability analyses. In complement to the limit ...
2003Continuous bounded cohomology of locally compact groups
The purpose of this monograph is (a) to lay the foundations for a conceptual approach to bounded cohomology; (b) to harvest the resulting applications in rigidity theory. Of central importance is the new interplay between measure theory, amenability, Banac ...
