Nonnegative Matrix Factorization with Transform Learning
Dylan Fagot, Cédric Févotte, Herwig Wendt
Traditional NMF-based signal decomposition relies on the factorization of spectral data, which is typically computed by means of short-time frequency transform. In this paper we pr…
Scaling in Internet Traffic: a 14 year and 3 day longitudinal study, with multiscale analyses and random projections
Romain Fontugne, Patrice Abry, Kensuke Fukuda +4
In the mid-90's, it was shown that the statistics of aggregated time series from Internet traffic departed from those of traditional short range dependent models, and were instead…
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…
