摘要:

在本文中,我们提出了一个深度学习框架TSCeption,用于从脑电图(EEG)中检测情绪。TSCeption由时间和空间卷积层组成,它们同时在时域和信道域中学习判别表示。时间学习器由多尺度1D卷积核组成,其长度与EEG信号的采样率相关,其学习多个时间和频率表示。空间学习者利用额叶区域情绪反应的不对称性来学习来自大脑左右半球的辨别性表征。在我们的研究中,一个系统被设计来研究沉浸式虚拟现实(VR)环境中的情绪唤醒。使用该系统从18名健康受试者收集EEG数据,以评估所提出的深度学习网络对低和高情绪唤醒状态分类的性能。该方法与SVM,EEGNet和LSTM进行了比较。TSception的分类准确率达到86.03%,显著优于现有方法(p<0.05)。代码可在https://github.com/deepBrains/TSception上获得

英文摘要:

In this paper, we propose a deep learning framework, TSception, for emotion detection from electroencephalogram (EEG). TSception consists of temporal and spatial convolutional layers, which learn discriminative representations in the time and channel domains simultaneously. The temporal learner consists of multi-scale 1D convolutional kernels whose lengths are related to the sampling rate of the EEG signal, which learns multiple temporal and frequency representations. The spatial learner takes advantage of the asymmetry property of emotion responses at the frontal brain area to learn the discriminative representations from the left and right hemispheres of the brain. In our study, a system is designed to study the emotional arousal in an immersive virtual reality (VR) environment. EEG data were collected from 18 healthy subjects using this system to evaluate the performance of the proposed deep learning network for the classification of low and high emotional arousal states. The proposed method is compared with SVM, EEGNet, and LSTM. TSception achieves a high classification accuracy of 86.03%, which outperforms the prior methods significantly (p<0.05). The code is available at https://github.com/deepBrains/TSception
