摘要:

癫痫是一种常见的神经系统疾病。及时预测癫痫发作并进行干预治疗可以显著减少患者的意外伤害,保护患者的生命与健康。本文提出了一种神经形态脉冲卷积Transformer,命名为Spiking Conformer,用于从头皮长期脑电图(EEG)记录中检测和预测癫痫发作片段。我们报告了Spiking Conformer模型在波士顿儿童医院-麻省理工学院(CHB-MIT)EEG数据集上的评估结果。通过利用基于脉冲的加法运算,与非脉冲模型相比,Spiking Conformer显著降低了分类计算成本。此外,我们引入了一个近似脉冲神经元层,在不牺牲准确率的情况下,将脉冲触发的神经元更新进一步减少了近38%。以原始EEG数据作为输入,所提出的Spiking Conformer在癫痫发作检测任务中实现了94.9%的平均敏感度和99.3%的特异度,在癫痫发作预测任务中实现了96.8%和89.5%的对应指标,并且与非脉冲等效模型相比,所需的运算次数减少了10倍以上。

英文摘要:

Epilepsy is a common disease of the nervous system. Timely prediction of seizures and intervention treatment can significantly reduce the accidental injury of patients and protect the life and health of patients. This paper presents a neuromorphic Spiking Convolutional Transformer, named Spiking Conformer, to detect and predict epileptic seizure segments from scalped long-term electroencephalogram (EEG) recordings. We report evaluation results from the Spiking Conformer model using the Boston Children's Hospital-MIT (CHB-MIT) EEG dataset. By leveraging spike-based addition operations, the Spiking Conformer significantly reduces the classification computational cost compared to the non-spiking model. Additionally, we introduce an approximate spiking neuron layer to further reduce spike-triggered neuron updates by nearly 38% without sacrificing accuracy. Using raw EEG data as input, the proposed Spiking Conformer achieved an average sensitivity rate of 94.9% and a specificity rate of 99.3% for the seizure detection task, and 96.8%, 89.5% for the seizure prediction task, and needs >10x fewer operations compared to the non-spiking equivalent model.
