Transfer Dynamics and Spectral Cascades in Graph-Coupled Kuramoto Networks

Marcin Kowalczyk, Pietro Liò, Zbigniew R. Struzik

This work introduces a spectral transfer formalism for nonlinear synchronisation dynamics to resolve how internal dynamical activity redistributes across network scales, moving bey…

Towards a Universal Measure of Complexity

Jarosław Klamut, Ryszard Kutner, Zbigniew R. Struzik

Recently it has been argued that entropy can be a direct measure of complexity, where the smaller value of entropy indicates lower system complexity, while its larger value indicat…

The new face of multifractality: Multi-branchedness and the phase transitions in time series of mean inter-event times

Jarosław Klamut, Ryszard Kutner, Tomasz Gubiec +1

Empirical time series of inter-event or waiting times are investigated using a modified Multifractal Detrended Fluctuation Analysis operating on fluctuations of mean detrended dyna…

Adaptive Decision Making via Entropy Minimization

Armen E. Allahverdyan, Aram Galstyan, Ali E. Abbas +1

An agent choosing between various actions tends to take the one with the lowest cost. But this choice is arguably too rigid (not adaptive) to be useful in complex situations, e.g.,…

Feature Learning from Incomplete EEG with Denoising Autoencoder

Junhua Li, Zbigniew Struzik, Liqing Zhang +1

An alternative pathway for the human brain to communicate with the outside world is by means of a brain computer interface (BCI). A BCI can decode electroencephalogram (EEG) signal…

Visualization of short-term heart period variability with network tools as a method for quantifying autonomic drive

Danuta Makowiec, Beata Graff, Agnieszka Kaczkowska +6

Signals from heart transplant recipients can be considered to be a natural source of information for a better understanding of the impact of the autonomic nervous system on the com…
