abstract = "Recently, a map from time series to networks has been proposed [7,
8], allowing the use of network statistics to characterize time
series. In this approach, time series quantiles are naturally
mapped into nodes of a graph. Networks generated by this method,
called Quantile Graphs (QGs), are able to capture and quantify
features such as long-range correlations or randomness present in
the underlying dynamics of the original signal. Here we apply the
QG method to the problem of detecting the differences between
electroencephalographic time series (EEG) of healthy and unhealthy
subjects. Our main goal is to illustrate how the differences in
dynamics are reflected in the topology of the corresponding QGs.
Results show that the QG method cannot only differentiate
epileptic from normal data, but also distinguish the different
abnormal stages/patterns of a seizure, such as pre-ictal (EEG
changes preceding a seizure) and ictal (EEG changes during a
seizure).",
