摘要

摘要:针对医疗诊断中癫痫脑电信号分类准确率低、分类类别少的问题，依据粒子群算法和支持向量机理论，提出了一种基于粒子群算法优化支持向量机参数的信号分类检测技术。首先利用小波分析对脑电信号进行5层分解与重构，然后提取含有癫痫特征频率的3、4、5层重构信号的波动系数和近似熵等特征，计算不同状态不同尺度的脑电信号能量，根据不同状态不同尺度的能量分布，调整特征向量的系数。最后使用粒子群算法优化的支持向量机对脑电信号进行分类。实验结果表明，本文提出的方法可以正确识别健康、癫痫发作间期、癫痫发作期3种类型脑电信号，最终的识别率可以达到99.83%。

Abstract

Abstract:Aiming at the problem of low accuracy and classification of epileptic EEG in medical diagnosis

a signal classification and detection technique based on particle swarm optimization (PSO) was proposed to optimize the support vector machine (SVM) based on the theory of particle swarm optimization and support vector machine (SVM).Firstly

the EEG signals were decomposed and reconstructed by wavelet analysis.Secondly

the coefficients of fluctuation and approximate entropy of the reconstructed signals containing the functional parameters of epilepsy were extracted. Finally

The support vector machine (SVM) optimized by particle swarm optimization (PSO) is used to classify the EEG signals. The experimental results show that the this method can correctly identify three types of EEG signals in healthy

interictal epilepsy and epileptic seizures

the final recognition rate can reach 99.83%.
