Significant progress has been witnessed in within-subject seizure detection from electroencephalography (EEG) signals. Consequently, more and more works have been shifted from within-subject seizure detection to cross-subject scenarios. However, the progress is hindered by inter-patient variations caused by gender, seizure type, etc.To tackle this problem, we propose a multi-view cross-object seizure detection model with information bottleneck attribution (IBA).Feature representations specific to seizures are learned from raw EEG data by adversarial deep learning. Combined with the manually designed discriminative features, the model can detect seizures across different subjects. In addition, we introduce IBA to provide insights into the decision-making of the adversarial learning process, thus enhancing the interpretability of the model.Extensive experiments are conducted on two benchmark datasets. The experimental results verify the efficacy of the model.
在从脑电图 (EEG) 信号中进行个体内癫痫发作检测方面取得了重大进展。因此,越来越多的工作从个体内癫痫发作检测转移到了跨个体场景。然而,由于性别、癫痫发作类型等因素引起的患者间差异,这一进展受到了阻碍。为了解决这个问题,我们提出了一种具有信息瓶颈归因 (IBA) 的多视图跨对象癫痫发作检测模型。通过对抗性深度学习,从原始 EEG 数据中学习到特定于癫痫发作的特征表示。结合人工设计的判别特征,该模型可以在不同个体之间检测癫痫发作。此外,我们引入了 IBA 来深入了解对抗性学习过程的决策过程,从而提高了模型的可解释性。在两个基准数据集上进行了广泛的实验。实验结果验证了该模型的有效性。
