Epilepsy is one of the most common cerebral diseases, the development of which can be divided into four states: interictal state, preictal state, ictal state and postictal state. Hunting for critical states is of great significance to predict seizures. This study seeks to establish a general-purpose method for epileptic seizure prediction by constructing individual-specific correlation networks between multi-channel EEG signals. In this paper, we present the mobile network information gain (M-NIG) method by transforming floating time series datasets into stable network information gain, which reduces the impact of data noise, thereby improving the robustness and effectiveness of the algorithm. The method not only efficiently predicts seizures but also detects their DNB channels. The proposed method attains an average of 97.40% accuracy, 94.32% sensitivity, 97.48% specificity, and FPR = 0.024/h on 22 patients from the public CHB-MIT scalp EEG database, which outperforms most state-of-the-art articles. Additionally, it achieves an average of 95.70% accuracy, 100.00% sensitivity, 95.56% specificity, and FPR = 0.044/h on a dataset collected at Taian Maternity and Child Health Hospital, which outperforms most state-of-the-art articles in terms of sensitivity, accuracy, and FPR. Our experiments show that the parameters of sliding window and the number of nearest neighbor of k-nearest neighbor (KNN) are important factors affecting prediction performance.
癫痫是最常见的脑部疾病之一,其发展可分为四个阶段:发作间期、发作前期、发作期和发作后期。寻找关键阶段对于预测癫痫发作具有重要意义。本研究旨在通过构建多通道脑电图(EEG)信号之间的个体特异性相关网络,建立一种通用的癫痫发作预测方法。在本文中,我们提出了移动网络信息增益(M-NIG)方法,即将浮动时间序列数据集转换为稳定的网络信息增益,从而减少数据噪声的影响,进而提高算法的鲁棒性和有效性。该方法不仅能有效地预测癫痫发作,还能检测出其可疑负性偏态(DNB)通道。所提出的方法在公开的CHB-MIT头皮EEG数据库中的22名患者上,平均准确率达到97.40%,灵敏度为94.32%,特异性为97.48%,误报率(FPR)为0.024/小时,优于大多数最先进的文章。此外,在泰安市妇幼保健院收集的数据集上,该方法平均准确率为95.70%,灵敏度为100.00%,特异性为95.56%,FPR为0.044/小时,在灵敏度、准确率和FPR方面优于大多数最先进的文章。我们的实验表明,滑动窗口参数和k近邻(KNN)的最近邻数量是影响预测性能的重要因素。
