Spectrum Estimation through Kirchhoff Random Forests
Simon Barthelmé, Fabienne Castell, Alexandre Gaudillière +3
Given a non-oriented edge-weighted graph, we show how to make some estimation of the associated Laplacian eigenvalues through Monte Carlo evaluation of spectral quantities computed…
Estimating a graph's spectrum via random Kirchhoff forests
Simon Barthelmé, Fabienne Castell, Alexandre Gaudillière +3
Exact eigendecomposition of large matrices is very expensive, and it is practically impossible to compute exact eigenvalues. Instead, one may set a more modest goal of approaching…
Approximate and exact solutions of intertwining equations through random spanning forests
Luca Avena, Fabienne Castell, Alexandre Gaudillière +1
For different reversible Markov kernels on finite state spaces, we look for families of probability measures for which the time evolution almost remains in their convex hull. Motiv…
Multifractal analysis based on p-exponents and lacunarity exponents
Patrice Abry, Stéphane Jaffard, Roberto Leonarduzzi +2
Many examples of signals and images cannot be modeled by locally bounded functions, so that the standard multifractal analysis, based on the Hölder exponent, is not feasible. We pr…
