Seizure is a common neurological disorder that usually manifests itself in recurring seizure, and these seizures can have a serious impact on a person's life and health. Therefore, early detection and diagnosis of seizure is crucial. In order to improve the efficiency of early detection and diagnosis of seizure, this paper proposes a new seizure detection method, which is based on discrete wavelet transform (DWT) and multi-channel long- and short-term memory-like spiking neural P (LSTM-SNP) model. First, the signal is decomposed into 5 levels by using DWT transform to obtain the features of the components at different frequencies, and a series of time-frequency features in wavelet coefficients are extracted. Then, these different features are used to train a multi-channel LSTM-SNP model and perform seizure detection. The proposed method achieves a high seizure detection accuracy on the CHB-MIT dataset: 98.25% accuracy, 98.22% specificity and 97.59% sensitivity. This indicates that the proposed epilepsy detection method can show competitive detection performance.
癫痫是一种常见的神经系统疾病,通常表现为反复发作的癫痫发作,这些癫痫发作会对人的生活和健康产生严重影响。因此,早期发现和诊断癫痫至关重要。为了提高癫痫早期检测和诊断的效率,本文提出了一种新的癫痫检测方法,该方法基于离散小波变换(DWT)和多通道长短期记忆类似尖峰神经元 P(LSTM-SNP)模型。首先,使用 DWT 变换将信号分解为 5 个级别,以获得不同频率分量的特征,并提取小波系数中的一系列时频特征。然后,使用这些不同的特征来训练多通道 LSTM-SNP 模型并进行癫痫发作检测。在 CHB-MIT 数据集上,所提出的方法实现了高的癫痫检测精度:98.25%的准确率、98.22%的特异性和 97.59%的灵敏度。这表明所提出的癫痫检测方法可以表现出有竞争力的检测性能。
