Transfer learning is one of the popular methods to solve the problem of insufficient data in subject-specific electroencephalogram (EEG) recognition tasks. However, most existing approaches ignore the difference between subjects and transfer the same feature representations from source domain to different target domains, resulting in poor transfer performance. To address this issue, we propose a novel subject-specific EEG recognition method named deep multiview module adaption transfer (DMV-MAT) network. First, we design a universal deep multiview (DMV) network to generate different types of discriminative features from multiple perspectives, which improves the generalization performance by extensive feature sets. Second, module adaption transfer (MAT) is designed to evaluate each module by the feature distributions of source and target samples, which can generate an optimal weight sharing strategy for each target subject and promote the model to learn domain-invariant and domain-specific features simultaneously. We conduct extensive experiments in two EEG recognition tasks, i.e., motor imagery (MI) and seizure prediction, on four datasets. Experimental results demonstrate that the proposed method achieves promising performance compared with the state-of-the-art methods, indicating a feasible solution for subject-specific EEG recognition tasks.

迁移学习是解决特定主题脑电图(EEG)识别任务中数据不足问题的常用方法之一。然而,大多数现有方法忽略了不同主体之间的差异,将相同的特征表示从源域转移到不同的目标域,导致迁移性能较差。为了解决这个问题,我们提出了一种新颖的特定主题EEG识别方法,称为深度多视图模块自适应迁移(DMV-MAT)网络。首先,我们设计了一个通用的深度多视图(DMV)网络,从多个角度生成不同类型的判别特征,通过广泛的特征集提高泛化性能。其次,模块自适应迁移(MAT)旨在通过源样本和目标样本的特征分布来评估每个模块,这可以为每个目标主体生成最优的权重共享策略,并促进模型同时学习域不变和域特定特征。我们在四个数据集上的两个EEG识别任务,即运动想象(MI)和癫痫预测中进行了广泛的实验。实验结果表明,与现有方法相比,该方法取得了良好的性能,为特定主题EEG识别任务提供了一种可行的解决方案。实现代码可在https://github.com/YangLibuaa/DMV-MAT获取。
