Abstract:
This paper addresses the prediction of epileptic
seizures from the online analysis of EEG data. This problem is
of paramount importance for the realization ofmonitoring/control
units to be implanted on drug-resistant epileptic patients. The proposed
solution relies in a novel way on autoregressive modeling of
theEEGtime series and combines a least-squares parameter estimator
for EEG feature extraction along with a support vector machine
(SVM) for binary classification between preictal/ictal and interictal
states. This choice is characterized by low computational requirements
compatible with a real-time implementation of the overall
system.Moreover, experimental results on the Freiburg dataset exhibited
correct prediction of all seizures (100% sensitivity) and,
due to a novel regularization of the SVM classifier based on the
Kalman filter, also a low false alarm rate.
