  • Serrà Julià, Joan; Serra, Xavier; Andrzejak, Ralph Gregor (Institute of Physics (IOP), 2009)
    There is growing evidence that nonlinear time series analysis techniques can be used to successfully characterize, classify, or process signals derived from realworld dynamics even though these are not necessarily deterministic ...
  • Serrà Julià, Joan; Kantz, Holger; Serra, Xavier; Andrzejak, Ralph Gregor (Institute of Electrical and Electronics Engineers (IEEE), 2011)
    Intuitively, music has both predictable and unpredictable components. In this work we assess this qualitative statement in a quantitative way using common time series models fitted to state-of-the-art music descriptors. ...
  • Chicharro Raventós, Daniel; Andrzejak, Ralph Gregor (American Physical Society, 2009)
    To detect directional couplings from time series various measures based on distances in reconstructed state spaces were introduced. These measures can, however, be biased by asymmetries in the dynamics' structure, noise ...
  • Chicharro Raventós, Daniel; Kreuz, Thomas; Andrzejak, Ralph Gregor (Elsevier, 2011)
    Time scale parametric spike train distances like the Victor and the van Rossum distances are often applied to study the neural code based on neural stimuli discrimination. Different neural coding hypotheses, such as rate ...
