The automatic detection of epilepsy is essentially the classification of EEG signals of seizures and nonseizures, and its purpose is to distinguish the different characteristics of seizure brain electrical signals and normal brain electrical signals. In order to improve the effect of automatic detection, this study proposes a new classification method based on unsupervised multiview clustering results. In addition, considering the high-dimensional characteristics of the original data samples, a deep convolutional neural network (DCNN) is introduced to extract the sample features to obtain deep features. The deep feature reduces the sample dimension and increases the sample separability. The main steps of our proposed novel EEG detection method contain the following three steps: first, a multiview FCM clustering algorithm is introduced, and the training samples are used to train the center and weight of each view. Then, the class center and weight of each view obtained by training are used to calculate the view-weighted membership value of the new prediction sample. Finally, the classification label of the new prediction sample is obtained. Experimental results show that the proposed method can effectively detect seizures.
癫痫的自动检测本质上是对癫痫和非癫痫的 EEG 信号进行分类,其目的是区分癫痫脑电信号和正常脑电信号的不同特征。为了提高自动检测的效果,本研究提出了一种新的基于无监督多视图聚类结果的分类方法。此外,考虑到原始数据样本的高维特征,引入了深度卷积神经网络(DCNN)来提取样本特征,以获得深度特征。深度特征降低了样本维度,增加了样本可分离性。我们提出的新型 EEG 检测方法的主要步骤包含以下三个步骤:首先,引入多视图 FCM 聚类算法,并使用训练样本训练每个视图的中心和权重。然后,使用训练得到的各视图的类中心和权重来计算新预测样本的视图加权隶属度。最后,获得新预测样本的分类标签。实验结果表明,所提出的方法可以有效地检测癫痫发作。
