Motivated by the challenge of seamless cross-dataset transfer in EEG signal processing, this article presents an exploratory study on the use of Joint Embedding Predictive Architectures (JEPAs). In recent years, self-supervised learning has emerged as a promising approach for transfer learning in various domains. However, its application to EEG signals remains largely unexplored. In this article, we introduce Signal-JEPA for representing EEG recordings which includes a novel domain-specific spatial block masking strategy and three novel architectures for downstream classification. The study is conducted on a 54~subjects dataset and the downstream performance of the models is evaluated on three different BCI paradigms: motor imagery, ERP and SSVEP. Our study provides preliminary evidence for the potential of JEPAs in EEG signal encoding. Notably, our results highlight the importance of spatial filtering for accurate downstream classification and reveal an influence of the length of the pre-training examples but not of the mask size on the downstream performance.

通过研究使用联合嵌入预测架构 (JEPAs) 在脑电信号处理中实现无缝跨数据集迁移的挑战，本文提供了一项探索性研究。我们在一个包含54个受试者的数据集上进行了研究，并通过三个不同的脑-机接口范式 (运动想象、ERP和SSVEP) 评估了模型的下游性能。研究结果初步证明了JEPAs在脑电信号编码中的潜力，并强调了空间滤波在精确下游分类中的重要性，同时揭示了预训练示例长度对下游性能的影响但掩蔽大小不影响。
