Epilepsy is a common and diverse set of chronic neurological disorders
characterized by seizures. It is a paroxysmal behavioral spell generally
caused by an excessive disorderly discharge of cortical nerve cells of
the brain. Epilepsy is marked by the term "epileptic seizures".
Epileptic seizures result from abnormal, excessive or hyper-synchronous
neuronal activity in the brain. About 50 million people worldwide have
epilepsy, and nearly 80% of epilepsy occurs in developing countries. The
most common way to interfere with epilepsy is to analyse the EEG
(electroencephalogram) signal which is a non-invasive, multi channel
recording of the brain's electrical activity. It is also essential to
classify the risk levels of epilepsy so that the diagnosis can be made
easier. This study investigates the possibility of Extreme Learning
Machine (ELM) and Continuous GA as a post classifier for detecting and
classifying epilepsy of various risk levels from the EEG signals.
Singular Value Decomposition (SVD), Principal Component Analysis (PCA)
and Independent Component Analysis (ICA) are used for dimensionality
reduction.
