From subexponential distributions to black swan dominance
Alexei Vazquez
The shape of empirical distributions with heavy tails is a recurrent matter of debate. There are claims of a power laws and the associated scale invariance. There are plenty of cha…
Impact of interactions on human dynamics
J. G. Oliveira, A. Vazquez
Queueing theory has been recently proposed as a framework to model the heavy tailed statistics of human activity patterns. The main predictions are the existence of a power-law dis…
Impact of memory on human dynamics
Alexei Vazquez
Our experience of web access slowing down is a consequence of the aggregated web access pattern of web users. This is just one example among several human oriented services which a…
Modeling bursts and heavy tails in human dynamics
A. Vazquez, J. Gama Oliveira, Z. Dezso +3
Current models of human dynamics, used from risk assessment to communications, assume that human actions are randomly distributed in time and thus well approximated by Poisson proc…
Exact results for the Barabasi model of human dynamics
Alexei Vazquez
Human activity patterns display a bursty dynamics, with interevent times following a heavy tailed distribution. This behavior has been recently shown to be rooted in the fact that…
