Seizures: Classification

Seizures: Classification

Epilepsy is primarily characterized by unpredictable seizures, either provoked by an identifiable factor, such as injury or illness, or unprovoked, occurring spontaneously without apparent cause.
Seizures are typically classified into two main categories: focal and generalized seizures.
Focal Seizures
Focal seizures originate from specific regions of the brain. These seizures are further sub-classified into two types:

Background:

Automatic diagnosis of epilepsy using Electroencephalogram (EEG) signals is a critical research area.
Existing methods face challenges in accurately distinguishing epileptic seizures from non-seizure states.

Purpose of the Study:

To propose a novel automatic epilepsy detection method.
To enhance the accuracy and reliability of epilepsy diagnosis through signal processing and machine learning.

Main Methods:

EEG signals were transformed into a complex network using a proposed multi-weight transition network algorithm.
Network characteristics, including degree and local entropy, were extracted as features.
Support Vector Machines (SVM) were employed for classifying epileptic and non-epileptic signals.

Main Results:

The proposed multi-weight transition network algorithm demonstrated high classification accuracy across seven experimental cases.
Feature extraction based on network statistical characteristics proved effective for epilepsy detection.

Conclusions:

The developed method offers a promising approach for accurate automatic epilepsy diagnosis.
The multi-weight transition network provides a robust framework for analyzing EEG signals in epilepsy detection.
