This survey paper reviews deep learning techniques designed to improve the generalization of electroencephalogram (EEG) decoding across different subjects. It addresses the challenge of high inter-subject variability, which creates a domain shift between training and testing data. The paper categorizes existing methods into families such as feature alignment, adversarial learning, feature disentanglement, and contrastive learning, while also discussing theoretical limitations and the potential of EEG foundation models.
