matlab投射转相除代码使用来自DEAP数据集的EEG进行人类情感分析 根据以下内容处理DEAP数据集 PSD(功率谱密度)和2)DWT(离散小波变换)功能。 根据Arousal和Valence(高/低)对EEG等级进行分类 在此处找到DEAP数据集:(您需要通过向授权人员发送邮件来下载以寻求许可) 可以使用matlab文件处理来自EEG的数据。 (适用于matlab版本的EEG数据集)将matlab文件直接保存在DEAP数据集文件夹中,数据位于该文件夹中。 运行process.m以获取功率谱密度文本文件 生成的每个testFile包含4个特征-alpha,beta,delta和theta波功率谱密度比(通过总psd归一化),分别表示价,唤醒和组合(价+声)的输出。 1->低,2->高 您可以在此处阅读有关脑电波的信息(概述): 您可以在此处查看唤醒和价态及其含义的图表: 使用psd功能和KNN / SVM可能不会获得很好的准确性,因为它们主要只是人类头脑存在的一种度量。 DWT分析可帮助我们获得基于频率的psd之外的基于时间的功能。 运行dwt_feature_extraction
