Abstract

The theory of complex networks has been successful in the attempt to provide information and a suitably representation of the relation between elements of distinct nature in different contexts. Recently, means of transforming time series in graphs have been attracting attention of researchers aiming to characterize physical process, specially, the biological or physiological ones, by means of its classical measures (degree, mean path length, cluster coefficient, etc). In this context, this master degree thesis aims to study a methodology for converting time series into complex networks for pattern recognition of EEG signals collected into the framework of brain-computer interface systems.
