摘要:

我们提出了一个卷积神经网络(CNN)辅助因子图的神经网络估计的癫痫发作检测的互信息功能的帮助。具体来说,我们使用神经互信息估计来评估不同的脑电图(EEG)通道之间的相关性作为特征。然后,我们使用1D-CNN从EEG信号中提取额外的特征,并使用这两个特征来估计癫痫发作事件的概率。最后,学习因子图被用来捕捉信号中的时间相关性。来自神经相互估计和1D-CNN的两组特征都用于学习因子节点。我们表明,所提出的方法实现了最先进的性能,使用6倍留四病人交叉验证。

英文摘要:

We propose a convolutional neural network (CNN) aided factor graphs assisted by mutual information features estimated by a neural network for seizure detection. Specifically, we use neural mutual information estimation to evaluate the correlation between different electroencephalogram (EEG) channels as features. We then use a 1D-CNN to extract extra features from the EEG signals and use both features to estimate the probability of a seizure event.~Finally, learned factor graphs are employed to capture the temporal correlation in the signal. Both sets of features from the neural mutual estimation and the 1D-CNN are used to learn the factor nodes. We show that the proposed method achieves state-of-the-art performance using 6-fold leave-four-patients-out cross-validation.
