In this paper, an algorithm based on the linear Support Vector Machine (SVM) tool was proposed to classify intracranial electroencephalography (iEEG) signals as ictal or interictal to perform human seizure prediction, efficiently. Various univariate linear measures were extracted, and the developed classifier performed adequately well with numerous performance metrics, especially the dataset was suffering from a significant imbalanced class, with the majority of samples representing non-seizure events. The proposed tool was indeed able to forecast accurately such rare events, seizures, from a large set of EEG dataset. In fact, our model can predict some seizures with up to 0.4 probability and about 30-40 minutes in advance. The proposed work employed intracranial EEG recordings of 6 patients in the Freiburg EEG database, totalling trained and tested on 34 seizures of 140-hour-long. It exhibits a sensitivity of 78% and specificity of 100% employing a 2-second-long window with 10-fold cross-validation.
在本文中,提出了一种基于线性支持向量机(SVM)工具的算法,用于将颅内脑电图(iEEG)信号分类为发作期或发作间期,以有效地进行人类癫痫发作预测。提取了各种单变量线性测量指标,所开发的分类器在众多性能指标方面表现良好,特别是该数据集存在严重的类别不平衡问题,大多数样本代表非癫痫发作事件。所提出的工具确实能够从大量脑电图数据集中准确预测此类罕见事件——癫痫发作。事实上,我们的模型能够以高达0.4的概率提前约30 - 40分钟预测一些癫痫发作。所提出的工作采用了弗莱堡脑电图数据库中6名患者的颅内脑电图记录,总共对时长140小时的34次癫痫发作进行了训练和测试。在使用2秒长窗口和10折交叉验证的情况下,其灵敏度为78%,特异性为100%。
