Asynchronously Trained Distributed Topographic Maps
Abbas Siddiqui, Dionysios Georgiadis
Topographic feature maps are low dimensional representations of data, that preserve spatial dependencies. Current methods of training such maps (e.g. self organizing maps - SOM, ge…
Global Collaboration through Local Interaction in Competitive Learning
Abbas Siddiqui, Dionysios Georgiadis
Feature maps, that preserve the global topology of arbitrary datasets, can be formed by self-organizing competing agents. So far, it has been presumed that global interaction of ag…
Pattern phase diagram of spiking neurons on spatial networks
Dionysios Georgiadis, Didier Sornette
We study an abstracted model of neuronal activity via numerical simulation, and report spatiotemporal pattern formation and critical like dynamics. A population of pulse coupled, d…
Using nonlinear stochastic and deterministic (chaotic tools) to test the EMH of two Electricity Markets the case of Italy and Greece
George P Papaioannou, Christos Dikaiakos, Anargyros Dramountanis +2
Utilization of non-linear tools to characterize the state of development of the electricity markets in Italy and Greece. This is equivalent to testing the Efficient Market Hypothes…
