abstract = "The advances in the development of Brain-Computer
Interfaces(BCI) have been increasing in recent years,
mostly because the level of convergence from
multi-disciplinary techniques has evolved. The
electroencephalography(EEG), a brain recording method
studied in this thesis, allows the construction of
BCIs, however the signals are rather complex to
process, which requires methodologies that efficiently
extract patterns from them. This thesis explores two
directions: first, a system is proposed for the
epilepsy seizures recognition using a combination of
signal processing methods for an efficient feature
extraction; second,it explores the usage of a
meta-heuristic algorithm, namely Genetic Programming
(GP), as an alternative in the design of BCIs.
Nonetheless,there is currently open-issues in GP that
this thesis also explores: is there a more efficient
search methodology in the exploration by GP?; what is a
proper representation depending on the studied
problem?; which are the most adequate search
operators?. For the first topic, a thoroughly study is
presented by introducing a memetic GP applied to
regression problems. Then, it is extended by adapting
it to classification problems. The results are
positive; GP is greatly benefited from the combination
of a general and a Local Search (LS) methodology. The
last two topics are studied simultaneously in the
development of a recognition system for mental states
using EEG. A GP version (+FEGP) is proposed that
evolves feature extraction models by using specialized
search operators,individuals representation and fitness
function. The results show that the combination of
these reaches a state-of-the-art accuracy for the
particular task of mental states recognition.",
