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:

Area of Science:

Neurology
Artificial Intelligence
Biomedical Engineering

Background:

Electroencephalogram (EEG) signal analysis is crucial for epilepsy detection.
Overfitting is a challenge in deep learning models due to limited EEG data.

Purpose of the Study:

To address overfitting in deep learning models for epilepsy detection.
To improve the accuracy and robustness of epilepsy detection using EEG signals.

Main Methods:

Utilized Adversarial and Mixup Data Augmentation (AMDA) to increase training samples.
Developed a one-dimensional convolutional neural network and gated recurrent unit (AM-1D CNN-GRU) model with an attention mechanism.

Main Results:

Epilepsy detection performance significantly improved with augmented data.
Achieved accuracy, sensitivity, and AUC of 96.06%, 95.48%, and 0.9637, respectively.
All performance indicators increased by over 6.2% compared to non-augmented data.

Conclusions:

The proposed AMDA and AM-1D CNN-GRU model enhances epilepsy detection accuracy and robustness.
The findings provide a valuable reference for the clinical application of automated epilepsy detection systems.
