In this paper, we propose LGG, a neurologically inspired graph neural
network, to learn local-global-graph representations from
Electroencephalography (EEG) for a Brain-Computer Interface (BCI). A temporal
convolutional layer with multi-scale 1D convolutional kernels and kernel-level
attention fusion is proposed to learn the temporal dynamics of EEG. Inspired by
neurological knowledge of cognitive processes in the brain, we propose local
and global graph-filtering layers to learn the brain activities within and
between different functional areas of the brain to model the complex relations
among them during the cognitive processes. Under the robust nested
cross-validation settings, the proposed method is evaluated on the publicly
available dataset DEAP, and the classification performance is compared with
state-of-the-art methods, such as FBFgMDM, FBTSC, Unsupervised learning,
DeepConvNet, ShallowConvNet, EEGNet, and TSception. The results show that the
proposed method outperforms all these state-of-the-art methods, and the
improvements are statistically significant (p<0.05) in most cases. The source

LGGNet:从局部全局图形表示中学习脑机接口
在本文中,我们提出了LGG,这是一种受神经学启发的图神经网络,用于从脑电图(EEG)中学习脑-计算机接口(BCI)的局部全局图表示。提出了一种具有多尺度一维卷积核和核级注意融合的时间卷积层,以学习脑电的时间动态。受大脑中认知过程的神经学知识的启发,我们提出了局部和全局图形过滤层,以学习大脑不同功能区域之内和之间的大脑活动,从而在认知过程中对它们之间的复杂关系进行建模。在鲁棒的嵌套交叉验证设置下,对公开数据集DEAP评估提出的方法,并将分类性能与最先进的方法(如FBFgMDM,FBTSC,无监督学习,DeepConvNet,ShallowConvNet,EEGNet和TSception。结果表明,所提出的方法优于所有这些最新方法,并且在大多数情况下,改进具有统计学意义(p <0.05)。可以在以下位置找到源代码:https://github.com/yi-ding-cs/LGG
