Online training of Echo State Networks to predict chaotic dynamical systems
Astero Provata, Markos Syroukis, Johanne Hizanidis
Echo State Networks (ESNs) are fundamentally important from the conceptual perspective of AI, because they provide simple and tractable frameworks for understanding temporal inform…
Multistable Synaptic Plasticity induces Memory Effects and Cohabitation of Chimera and Bump States in Leaky Integrate-and-Fire Networks
Astero Provata, Yannis Almirantis, Wentian Li
Chimera states and bump states are collective synchronization phenomena observed independently (at different parameter regions) in networks of coupled nonlinear oscillators. And wh…
From Turing patterns to chimera states in the 2D Brusselator model
Astero Provata
The Brusselator has been used as a prototype model for autocatalytic reactions, and in particular for the Belouzov- Zhabotinsky reaction. When coupled at the diffusive limit, the B…
Chimera states formed via a two-level synchronization mechanism
Astero Provata
Chimera states, which consist of coexisting synchronous and asynchronous domains in networks of coupled oscillators, are in the focus of attention for over a decade. Although chime…
Constructive approach to limiting periodic orbits with exponential and power law dynamics
Astero Provata
In dynamical systems limit cycles arise as a result of a Hopf bifurcation, after a control parameter has crossed its critical value. In this study we present a constructive method…
Chimera states in population dynamics: networks with fragmented and hierarchical connectivities
Johanne Hizanidis, Evangelia Panagakou, Iryna Omelchenko +3
We study numerically the development of chimera states in networks of nonlocally coupled oscillators whose limit cycles emerge from a Hopf bifurcation. This dynamical system is ins…
