Abstract

The Spatio-temporal feature fusion epilepsy recognition model achieved 95.18% accuracy on single-validation tests from the CHB-MIT dataset.

A novel model eliminates the need for extensive data preprocessing and feature extraction in detecting epileptic seizures from EEG signals.
The model uses a multi-channel framework and incorporates a dual attention mechanism to improve accuracy.
On the Bonn University dataset, the model attained 77.65% accuracy in single-validation tests.
In 10-fold cross-validation tests, accuracy rates were 92.42% for CHB-MIT and 67.24% for Bonn University.
Current deep learning approaches, including CNNs and LSTMs, face limitations that this new model aims to address.

In the field of clinical neurology, automated detection of epileptic seizures based on electroencephalogram () signals has the potential to significantly accelerate the diagnosis of epilepsy. This rapid and accurate diagnosis enables doctors to provide timely and effective treatment for patients, significantly reducing the frequency of future epileptic seizures and the risk of related complications, which is crucial for safeguarding patients' long-term health and quality of life. Presently, deep learning techniques, particularly Convolutional Neural Networks (CNNs) and Long Short-Term Memory networks (LSTMs), have demonstrated remarkable accuracy improvements across various domains. Consequently, researchers have utilized these methodologies in studies focused on recognizing epileptic signals through EEG analysis. However, current models based on CNN and LSTM still heavily rely on data preprocessing and feature extraction steps. Additionally, CNNs exhibit limitations in perceiving global dependencies, while LSTMs encounter challenges such as gradient vanishing in long sequences. This paper introduced an innovative EEG recognition model, that is the Spatio-temporal feature fusion epilepsy EEG recognition model with dual attention mechanism (). STFFDA is comprised of a multi-channel framework that directly interprets epileptic states from raw EEG signals, thereby eliminating the need for extensive data preprocessing and feature extraction. Notably, our method demonstrates impressive accuracy results, achieving 95.18% and 77.65% on single-validation tests conducted on the datasets of CHB-MIT and Bonn University, respectively. Additionally, in the 10-fold cross-validation tests, their accuracy rates were 92.42% and 67.24%, respectively. In summary, it is demonstrated that the seizure detection method STFFD based on EEG signals has significant potential in accelerating diagnosis and improving patient prognosis, especially since it can achieve high accuracy rates without extensive data preprocessing or feature extraction.
