嗜睡/困倦(Drowsiness)是道路交通事故的主要原因之一,因为它会对驾驶员安全驾驶汽车的能力产生负面影响。EEG(Electroencephalograph,EEG)电极记录的神经活动是一个广泛应用的与驾驶员睡意相关的生理特征信号。本文提出了一种利用EEG信号评估驾驶员瞬时水平睡意的动态建模方法,其中眼睑闭合度(PERcentage of eyelid CLOSure,PERC...
在DEAP和SEED上,对不同的特征提取、特征选择、特征平滑和模式分类方法进行了系统的比较和定性评价。 采用一种 discriminative Graph regularized Extreme Learning Machine (GELM) 去确定稳定模式和用交叉会话计划评估情感识别模型的稳定性。 结果表明,三种情绪的神经信号确实存在,关键频段和大脑区域的脑电图模式在会话内...
We utilised the signal values from each EEG channel at each time point as features for individual nodes. The construction methods of the adjacency matrix, which captures brain connectivity, are elaborated in Sections 3.4 Graph preliminary, 3.5 EEG Graph Lottery Ticket (EEG_GLT). The training data...

EEG features values classificationHello. I have an exercise in which 4 features from EEG are extracted(delta, theta ,alpha, beta). I was asked to visualize the features values belonging to each class, seizure on non seizure. And after that to compute the mean and the standard deviation of ...
大量的研究已经表明,精神分裂症(schizophrenia, SZ)的临床和认知症状最好用不同脑区之间的连接异常而不是某个特定脑区的异常来解释。EEG/MEG的γ频段振荡活动似乎在涉及高级认知功能的局部和大规模神经元同步化中起着关键作用,而很多高级认知功能在SZ患者身上往往表现出
